Check Engine Light After Oil Change Got an oil change today with 5W 30 at the local Jiffy lube and a new intake air filter (not the main filter on the engine the one against firewall). Suddenly like 1 km away, the check engine light came on. Won't turn off. I reset the oil sensor according to owners manual
2009 Chevrolet Equinox P0171 While trying to correct these problems, the service traction system light came on. We scanned the computer and also got code P2534.
Tammy said: I have an 07 Chevy equinox ... sometimes when I cranking up the temperature gauge is already on half way mark and then it settled on hot. Other times when I crank it, it's on cool so when it settled it's on normal (halfway) and so on. It just depends on where the hand is when I first crank it as to where it is going to settle. Could this be the temperature sensor?
Mechboy said: Reply @Tammy, It could be the coolant temperature sensor on the engine, or even the gauge in the dash itself. Maybe the needle is sticking. You would need to either have a scanner on the truck to look at the coolant temp sensor reading and compare it to what the gauge says. If the scanner says the sensor reads 70 degrees, but the needle is at half way, then the gauge is sticking.
