I have a 2008 chevy equinox and i really love it, but i cannot get to the engine light problem. I already had it tune up changing all wires and spark plugs, two sensor and a the coil. i keep up with the maintanance of the vehicle. the problem im having is that when we use the remote started, the engine light come on. can you help me and give me some kind of solution, please
Have the computer scanned. Most auto parts stores will do it for free. Post the trouble codes here and we can help further. My first guess is an oxygen sensor fault. The computer runs a test on them when started cold and at idle. But that's just a guess. The trouble codes will tell the tale. HTH. -Jim
anytime you have a sensor replaced on your car the battery should be disconnected that way the code that has been sent to the ECM is removed out of the memory, and when it has been repaired the check engine light shouldn't come back on for that particular sensor. keep in mind that you should get a specific O2 sensor code bank 1 downstream or upstream sensor and the same for bank 2 most newer vehicles have 4 O2 sensors on them if they have dual exhaust

dont forget to unhook your battery so it resets computer after u change egr valve it worked for me you tube also is a huge help with hands on repairs
