I have a check engine light code p2238 replaced A/F sensor bank 1 with oem part cleared the code started the engine, light goes off but comes back on after a few minutes. How do you trouble shoot or what else should look for. Also replaced EFI and A/F relays. No other codes come up.

Thanks was thinking ECM can't see anything wrong with wiring.

I wouldn't worry about it.
Sometimes the car has a malfunction with the wiring system, I have the check engine light on but it's because the 02 sensor needs to be replaced, I checked it, it doesn't need to, after a while the check engine light turned off
How many miles?
