Engine Performance problem
2005 Mazda MPV 6 cyl Two Wheel Drive 92,000 miles
I'm getting p0134 (O2 sensor CKT No activity Bank 1 sensor 1) and P0154 (O2 sensor CKT No activity Bank 2 sensor 1). I've replaced the Upstream O2 sensor and I'm still getting the same 2 codes. Before I replace the Downstream sensor I want to make sure if I'm headed in the right direction
have the same problem?
