Your Chrysler, Dodge, Jeep or Ram vehicle has an intricate computer system to monitor numerous systems on your vehicle and ensure everything is working correctly. When there are problems with one or more systems, the check engine light on the dashboard will light up.
If your check engine light is on or comes on intermittently, you need to have your vehicle inspected at your nearest authorized Chrysler vehicle service center. The computer in your vehicle saves different error codes the service technician can recover to determine what is wrong.
These codes vary, from one make and model to the next, and there are different retrieval processes based on the model year. Attempting to recover the codes on your own could result in further damage to the systems on your vehicle, as well as the onboard computer system. As such, it is a good idea to have the error codes recovered by a factory-trained Chrysler service technician.
What Systems Are Inspected When the Check Engine Light Is On?
The first thing your Chrysler service technician will do is retrieve the error codes from the onboard computer. Once the codes have been retrieved, he or she will use these to diagnose what systems need to be inspected.
For instance, one common problem is the emission system. This system helps to prevent the release of harmful gases into the air and reduces the amount of pollution created by your vehicle. The emission system on your vehicle consists of several different sensors and subsystems, including:
- Oxygen Sensor – The oxygen sensor records the amount of air being mixed with fuel as it enters the engine. When it malfunctions, it can cause several problems, from stalling to a loss of power.
- Ignition System – If there is a problem with this system, it can increase the amount of harmful gases being created by the engine. Your spark plugs, engine timing, or distributor cap may need to be serviced.
- Fuel Sensor/Meter – This sensor monitors and regulates the amount of fuel being released into the engine.
- Air Injection System – This system draws air into the vehicle and works simultaneously with the fuel sensor/meter and oxygen sensor.
- Vacuum System – If there are leaks in the vacuum system, they can cause problems with other sensors and systems on the vehicle.
- Exhaust System – This system consists of the exhaust pipes and catalytic converter. It keeps your car running quieter, as well as removes pollution and many of the harmful gases created while the engine is running.
In our example, if the error code indicates a problem with the emission system, then each of the above may need to be inspected to determine what needs to be fixed.
TIP: If you notice dark-colored smoke coming from the tailpipe, this is a good indication that something is wrong with the engine and/or emission system.
