CODE question P2A00

markgutZ

Was just driving at the highway.. and im out of nowhere cel pops up.

The code was p2a00.

Im not sure if do i have to replce some of the sensors, or check for leaks..

My car is stock. But the previous owner put a hole on the mid pipes to make the sound louder.. would that be it?

I just need an advice on what should i do or what should i replace..
Thank you so much!

That's more than likely the problem - plug the hole(s) and see what happens. You could have a bad O2 sensor, especially if you have a lot of miles on the car, but the hole needs to be plugged for proper operation.

Monitoring the O2 sensors with an OBD/CAN tool will help you troubleshoot. The FSM (link in my sig) is a valuable (and free) resource for all DIYers.

Put a hole in the mid pipe. Please shoot me.
