Check engine light service near me in Olathe KS

When it comes to your check engine light, our auto repair and service specialists at L&D Auto are well-versed in engine light codes and diagnostics, so if your engine light comes on, contact our center right away and rest assured that your vehicle will receive the best possible care at an affordable price

There are hundreds of codes that could cause your check engine light to come on. Even the most common reasons can have a plethora of causes.

Some of the most common check engine light codes are:

  • There is a problem with the mass air flow (MAF) sensor or circuit.
  • The system is running too lean: Oxygen sensor detected a lean condition (too much oxygen in the exhaust).
  • Oxygen sensor detected a rich condition in the system (or too high a fuel to oxygen ratio).
  • Cylinder misfire: A P0300 code indicates that your engine has a random or multiple misfire.
  • Knock sensor circuit malfunction: Your vehicle's computer constantly adjusts and resets the engine to prevent damaging pre-ignition detonation or knock.
  • Improper exhaust gas recirculation (EGR).
  • Catalytic converter flow system Below efficiency threshold

These are just a few examples of the hundreds of codes, causes and symptoms available. Each has a number of solutions.

What does the check engine light indicate?

Sensors in your engine monitor the operation of its various systems and communicate with a system known as On-Board Diagnostics II (OBD-II). Note that pre-1996 vehicles have an older version of the diagnostic system. When something is not working properly, the check engine light comes on to alert you.

A flashing or blinking check engine light indicates a more serious problem.

Check engine lights can vary from manufacturer to manufacturer. The light is orange, yellow or red and shows the outline of the car's engine, sometimes with the words "check engine."

There are two types of warnings:

  • Check engine light on: If the symbol comes on and stays on for an extended period of time, it could indicate a number of problems and should be taken to an auto repair shop soon.
  • Check engine light flashing or blinking: If the symbol is blinking or flashing, there is a more serious problem. L&D Auto recommends to stop the vehicle in a safe place, turn off the engine and have the vehicle towed to a repair shop for diagnosis.

What is the cause of the check engine light and what should you do?

Consider the following scenario: You are in the middle of a long trip when the check engine light on your dashboard begins to blink. This could be an indication of a major problem, requiring you to take immediate action.

You would have to go to the nearest auto repair shop to have the problem fixed. In some cases, you could fix the problem yourself if you knew the most common faults related to the ignition of the check engine light.

Technically, the check engine light is known as the malfunction indicator light. It is a signal from the car's engine computer system that something is wrong with the machinery.

Prior to 1996, car manufacturers had their own engine diagnostic systems, which were used primarily to ensure that the vehicle met Environmental Protection Agency (EPA) pollution control requirements.

Car models manufactured after 1996 must adhere to the OBD-II protocol, which requires all automakers to provide a universal interface to access standardized trouble codes generated by the car's diagnostic system.

The check engine light is usually amber, orange or yellow in color. A flashing check engine light indicates a serious problem, while a steady check engine light indicates a potential problem. These problems can range from minor, such as a faulty gas cap, to major, such as an engine misfire leading to a faulty catalytic converter.

The importance of the check engine light

The car's computer operates and monitors the engine, reporting any faults to the driver through the check engine light. It is an important system of the car. The various parts of the vehicle operate at high temperatures and, if faulty, can cause a fire.

In addition, this system allows the car owner to become aware of defective but less expensive parts of the car early enough for replacement, which prevents the car owner from having to pay for expensive parts that may be damaged due to the negligence of smaller, less expensive components.

Troubleshooting Check Engine Light Problems

The first step is to read the code provided by the computer system in the car. This is the data that your engine sensors have collected. It can be read using scanners or OBD II readers through an OBD port, which is usually located under the steering column.

There are three ways to read the code:

  • Pay a diagnostic fee and take the car to a mechanic. If you agree to have the necessary service performed at that shop, the fee is usually waived.
  • Take your vehicle to an auto parts store and the code will be read for free. The free engine light diagnostic is helpful because if the code is for something minor, you may be able to fix it yourself.
  • Buy an inexpensive scanner and read the code yourself. This is an especially good option if you have an older vehicle that occasionally shows a check engine light for minor problems. Scanners can be purchased for as little as $15, and some transmit the data wirelessly to your cell phone.

Common reasons for a check engine light

A check engine light can be caused by a variety of problems, some of which are more common than others. Consult your mechanic or consider purchasing an OBD-II code reader to correctly identify your problem.

  • Gas cap has come loose: tighten the gas cap. If it has come off, buy a new one.
  • The oxygen sensor is faulty: You will need to replace it, but first find out which one is faulty.
  • The spark plugs may be fouled or faulty: Replace the spark plugs.
  • Spark plug wires are a problem: Replace the spark plug wires if necessary.
  • Catalytic converter is broken: Inspect and possibly replace the device with a mechanic.
  • The mass air sensor is defective, and will need replacement.

How much does it cost to repair a car's check engine light problems?

Today's motorists are feeling the pinch as both new car prices and fuel costs rise, but there is some good news to report on the automotive affordability front. The average cost to repair a "check engine light" related problem is down 10% in the last year, and is 15% lower than in 2006. The national average cost to repair a car engine light is now $357, which includes parts ($216) and labor ($141).

That's according to the 2018 Vehicle Health Index of check engine-related problems conducted by auto repair website CarMD , which is based on an analysis of more than 7 million repairs performed last year. The full report is available here.

In addition, the study confirms what many experienced car owners already know: older vehicles suffer more expensive and serious engine overhaul problems than newer models. According to CarMD, a 2017 car or truck is more likely to have a loose or faulty gas cap, which is a free fix, while a 2007 model is more likely to have a bad ignition coil, which will cost an average of $368. (which includes installation of a new set of spark plugs).

When it comes on, the check engine warning light, denoted by an outline of a car's engine or by the words themselves, usually indicates a malfunction in the ignition, fuel injection or emission control system. A technician can quickly diagnose a problem by connecting a hand-held diagnostic device to the car's OBD II port (usually located under the dashboard) and reading the five-digit error code.

A faulty oxygen sensor (average repair cost: $238), ignition coil/plugs ($367), catalytic converter ($1,271), fuel tank cap ($26) and an EVAP purge control valve ($147 - helps prevent fuel vapors in the tank from escaping into the atmosphere) are the five most common problems identified in the 2018 Vehicle Health Index.

According to CarMD, those in the Northeast pay the most for overhaul engine repairs, averaging $367, while those in the South and West pay the least, with a (only nominally lower) price tag of $358.

What's the worst that can happen if your check engine light comes on? Here's what you'll have to spend on average to cover the cost of the ten most expensive fixes (including parts and labor), according to CarMD:

Engine replacement costs $7,050.

  • Replace the electronic power steering unit: $5201
  • Replace the transmission assembly/reprogram the electronic control module: $5130.
  • Replace the transmission and torque converter: $5051
  • Replace the audio and visual control unit $429
  • Replace the transmission and torque converter box: $4245
  • Replace the hybrid car battery and reprogram the electronic control module: $4149
  • Replace the compu-valve module: $4105
  • Replace the transmission assembly: $3905
  • Replacement of the hybrid car battery: $3,798

The resulting error code, on the other hand, could specify a relatively inexpensive fix, as CarMD's list of the ten cheapest engine check problems demonstrates:

  • Inspect and, if necessary, replace a loose fuel cap: $26
  • Replace the air conditioning compressor clutch relay: $38
  • Replace the electronic engine control fuse: $46
  • Confirm diagnostic trouble codes: $47.00
  • Repair an engine/body ground wire: $48
  • Clean the ground wire: $49
  • Replace the vacuum hose for the exhaust gas recirculation pulse sensor: $52.00
  • Inspect air filter and make sure air box is tightly closed: $53
  • Replace the fuse for the electronic throttle control system: $53
  • Replace the vacuum hose on the secondary air injection control solenoid valve: $55

Check engine light frequently asked questions

The powertrain control module (PCM) in your vehicle is the computer that monitors the normal operating range of the various components in your vehicle. It has electronic sensors throughout your car, so if something is wrong, the check engine light will alert you that there is a problem. You should then make an appointment with a professional mechanic to determine the exact cause of the alert. A loose gas cap, a problem with the mass air and oxygen sensors, and malfunctioning spark plugs and catalytic converter are common problems. Only after a complete computer diagnosis has been performed can you be sure what is happening.

Why is my check engine light on?

If you are driving, don't panic; instead, pull over. Sometimes it is safe to drive a short distance with the check engine light on, but if you don't know what is wrong with your vehicle, it is best to pull over. Once you have stopped safely, go through this checklist to see if there is anything serious. Once you've determined whether or not you need a tow, the next step is to schedule a car computer diagnostic to have your car inspected by a car care expert who will be able to diagnose the problem and provide service to fix it right away.

The experts at L&D Auto will use state-of-the-art diagnostic tools, perform road tests and dig deeper into your vehicle until we can ensure it's fixed and ready for the road.

What should I do if the check engine light comes on?

When the check engine light comes on, the symbol on your dash is typically a solid light that remains illuminated until the problem is resolved. Driving with the light on is not recommended, but a solid check engine symbol indicates that you are most likely OK if you schedule an appointment with a mechanic soon.

However, if the light is flashing, it usually indicates a serious problem with your engine. Pull over, turn off your car and call a tow truck if the check engine light is flashing. Before driving your car again, take it to the nearest VATire store and run an engine diagnostic to determine the source of the problem.

What is causing my check engine light to blink?

You will not need repairs every time the check engine light comes on. Sometimes all you need to do is tighten the gas cap and that's it. The check engine light, on the other hand, is usually an indication that there is a serious problem with your car that needs to be taken care of.

Whatever the problem is, taking your car to have it checked by a car care expert is the best way to fix any current problems with your car and avoid future damage. Trained mechanics can read your vehicle's computer and determine what repairs are needed, if any.

Will I need repairs if the check engine light comes on?

If automakers thought something wasn't important, they wouldn't have designed a special light for it. If your check engine light comes on, it indicates that something is wrong. If your check engine light has previously gone out on its own, it means that the component that was causing the alert has returned to its normal operating range and has stopped alerting your PCM. If this is a recurring problem on your vehicle, it could easily come back out and cause problems. When the check engine light illuminates, it's time to schedule a diagnostic run of the car's computer.

Is it okay if I ignore the check engine light?

you would never be able to tell any body work was needed! It is so nice to have found a place I can trust

I have had my car for 6 years and needed some minor body work. I also wanted a “detail” done to make my car feel new again. This was my first time working with this business.

The service was great and affordable. Jose was very nice and told me about the condition of my car and the possible repairs

I found L&D Auto Specialist using Google search and I was skeptical at first. I wasn't sure what to expect of this auto repair shop. I guess I didn't want to walk into an expensive auto shop. I needed transmission service and we all know it's not cheap. The service was great and affordable. Jose was very nice and told me about the condition of my car and the possible repairs that I will have to do soon...
