Had my oil changed at a place and they told me my check engine light my come on after doing so. He told me how to reset it however I can not remember how he said to do it.Anyone know about this??
Wrong the check engine light is in no way related to the oil change. It is an indicator for all your modules in the car. Now if your trying to get the light off so you can smog or something, as long as the problem will not make the light come right back on, disconnect your pos batt cable for 30 sec BIG WARNING, if you have an aftermarket alarm it will reset and be active, all your memory settings in your radio,seat, climate control, transmission and adaptive memory, softwear file updates may and can be lost and set to default. Find out what the fault code is and fix the problem Good Luck
I have done several oil changes on Chrysler LHS models and never had a check engine lamp come on after it was done or fortold of a check engine light may come on. Oil changes do not cause check engine lights to come on. This person who did this oil change may have broken something or disconnected something possably. How else would this person know it may come on? Sounds a little fishy to me. I would talk to this persons manager about this if I were you. GOOD LUCK
Total BS, the CEL function is to warn operators of malfunctions detected by any of the cars onboard diagnostic systems, powertrain, body, transaxle, etc. Many faults may illuminate the light, if serious enough it will flash at you, indicating a serious problem which may be unsafe for youor damaging to the vehicle. If the CEL light is , or has illuminated there will be a diagnostic code stored in the PCM, or TCM, etc. This will indicate the area or circuit which has been involved in a failure event. Some failures take more than one event to set a hard code, but the problem will still be stored as an indicator for up to 55 start cycles.
