So I was working on my friends 01 and the check engine light came on! All I did was pull her stereo out and put it back in... its an after market sony unit. Any possible ideas? I pulled on the stereo harness to get some room but nothing else? Need a response asap!

It's an OBDII car. It's an incredibly complex piece of machinery.

Obviously throwing a CEL isn't something that should normally happen when you change out the radio, so this isn't a common solution. We're not going to be able to diagnose this over the internet. Go to Autozone and have them pull the code and go from there.

It's a dumb question, but are you sure it's the Check-engine light and not the maintenance required light?

yea a scan tool works wonders!!

actually you can diagnose it here. there is a diagnostic port you can take a paper clip and put it in plug 4 and 9 i believe and turn the key on and your CEL will blink. follow the blinks and match the numbers to the code. try that

Good news! She drove the car to school this morning and it shut off!

that sounds like a problem with a air sensor or something, if it's going on and off

You running an aftermarket intake? Bc I just posted a thread about that and Ik that the aem one pulls on the wires going to the IAT sensor which thanks to homeless I was able to fix it. But first go get the codes.
