2007 Saturn Ion Q&A
2007 Saturn Ion Question: Why would both of my check engine lights be on?
Both of my check engine lights come on and sends the car into reduced power mode. The code comes back with a bad throttle body. They have replaced my gas peddle four times and replaced the wiring harness and it's still doing it. They can't figure out the problem and I'm really getting sick of taking it in and paying more money for it not to be fixed. I have had it in the shop more times than I can count. - j1975
It means your car has the obd2 trouble code, you need check out the code first. - chinasinoy
