I have a 2004 Chevy Cavalier LS sport. Recently the check engine light turned on. The code indicated a problem with the fuel pump. The fuel pump was changed since then. However, now when I go to back up the trac off, ABS, service light, and check engine light will turn on. any suggestions?

SOURCE: service engine light and abs senor light will not turn off

Some times the wheel speed sensor will go out on either side. This will make the A.B.S. light come on. But I dont see why the service engine light would come on. I would segest changing all wheel speed sensors and take it for a drive. The A.B.S. light should go out. If the service engine light dose not go out your local auto parts stors can run a diagnostics test to tell you what the light is on for.

Please contact me if your problem presists.

Thanks, Charlie

no you need to take it and have the codes pulled on it, the abs system will disable the traction control system.Without knowing what the codes are for the abs system it would not be possible to say what the problem is.

SOURCE: cooling fan not turning on engine light and trac

Have the alternator checked.

SOURCE: ABS,TRAC OFFand SERVICE come on when starting out

check the abs sensors and connections of the sensors also that the sensor connection is attached to the clip[part of the circuit if wiring and connections are good then have car scanned most auto stores such as auto zone / advanced auto do this service for free check ur local area the trouble code will pinpoint ur problem so ur can repair ur car

SOURCE: how do I turn off

Service light can be turned if with an OBII scanner (Autozone or any good parts store can reset service light for FREE) The ABS & trace control lights are in because you have a wheel sensor(s) that are bad - replace bad sensor and then a certified shop or dealer has to reset ABS light (EXPENSIVE TOOL)
