i have a h22 EG and my o2 sensor code threw. So i went and bought a new one and rset the ECU. Well i was driving the next day and it tripped again. So i figured it must be a bad sensor. So i exchaged the sensor for another one and the same thing happened. How many sensors do i have. I thought only one. What could be causing this???

 

eg only has 1. what code is it specifically?

 

it is code 1... so for a H22 that is the oxygen sensor

 

maybe the O2 is throwing a code for the actual condition. Maybe your car is running rich or has a partially blow head gasket. Its hard to tell

 

the head gasket was replaced when i got the swap done 3 months ago
