HI, I have a 2007 H3 and check engine light is on. I change the oxygen sensor and reset the light but after some time it jumps on again.
Do somebody know what could be happening?
What I can do to solve the problem?

 

i think theres more than one o2 sensor

 

This is the location to introduce yourself, not for tech questions. So, take a deep breath and come on back here and say Hi.

Your question about your itty bitty little problem has been moved to the H3 section.

Thanks and welcome to the forum.
