Hello, having some issues with the o2 sensor on my ep3. The downstream o2 on my car needed to be replaced since something in the road caught the wires and ripped them out of the connector while driving. The car had no CEL and passed emissions no problem before. The car does have a test pipe with 2 non-foulers which worked before. so i bought a new o2 sensor. I installed it and I am getting a p0138 (bank 1, sensor 2 o2 high voltage). I reset my ecu instead of using the scanner to clear. And so far the Check engine light has been off. I noticed that i see a pending p0138 though, but i have driven the car for a pretty long time and before i reset the ECU it came on maybe 10 miles after i cleared the codes. I have driver 50-60 miles after the reset. Highway, constant 40mph, traffic, idle.. It just scared me that its pending. Just curious if that means something that its only pending. Could not find the exact info im looking for.

 

I would check the wiring since it had been ripped before. Maybe an issue there...
