Free Code Retrieval Process
Our Free Check Engine Light Code Retrieval Service provides you with quick and accurate answers from a Professional Automotive Technician. Think it might be a loose gas cap? We can simply verify that for you and reset the light. There are times when other codes are pulled indicating other problems. In this situation with information retrieved from your car’s computer, we can offer suggestions on what to do next. You might want to tackle it yourself or have one of our trained ASE Certified Technicians perform the repairs for you.
Complete Engine Performance Diagnostics
There are times when pulling a simple code will not be enough. Our technicians will have to dig deeper using the latest in manufacturer level diagnostic information and tools. Depending on the complexity of the diagnosis, it could take as long as 2 to 3 hours to complete. Need help? Call or Request an appointment today.
Want To Know More?
The Check Engine Light (which is actually the Malfunction Indicator Lamp or MIL) alerts you when an emissions-related problem occurs with the engine control system or emission controls on your vehicle. Depending on the nature of the problem, the Check Engine Light may come on and remain on continuously or flash. Some intermittent problems will make the Check Engine Light come on only while the fault is occurring (such as engine misfire). The Check Engine Light usually remains on once a fault has been detected, and will remain on to remind you that a problem has occurred that needs to be investigated.
When the Check Engine Light comes on, a diagnostic trouble code (DTC) is recorded in the powertrain control module (PCM) memory that corresponds to the fault. Some problems can generate more than one trouble code, and some vehicles may have multiple problems that set multiple trouble codes.
So Many Possibilities
The reasons for a check engine light activation range from something as simple as a loose gas cap to something as serious as a faulty catalytic convertor. Below is a list of a few of the possible problems that could cause your Check Engine Light to activate.
- Loose gas cap
- Problem with the MAF sensor or circuit
- System running too lean or too rich
- Cylinder misfire
- Knock sensor circuit malfunction
- Insufficient EGR (Exhaust Gas Recirculation) flow
- Catalyst system efficiency below threshold
- Faulty oxygen sensor
These are just a few of the hundreds of causes and symptoms that would result in an engaged check engine light.
