Originally posted by ethan: ...it read off code 171, as usual, but this time it was accompanied by code 133, which relates to an o2 sensor. i was told where the MAF sensor was and that's how i came to mess with it, but i have virtually no under-hood experience and i don't know where either of the o2 sensors are located. is it possible i could have damaged one while working with the air hose? ...
0133 is also related to MAF for the I4 Zetec 2.0
Per TSB, Electrical: �· Shorted/open wiring �· PCM Induction System: �· MAF sensor (On 4-cylinder engines, if P0133 is present, this could be caused by a MAF issue - on 6- and 8-cylinder engines, this could only be a MAF issue if P0133 and P0153 are both present) �· Inlet air leaks (unmetered air) Fuel Concerns: �· Poor fuel quality Base Engine: �· Exhaust leaks (upstream or near HO2S) HO2S Concerns: �· Contaminated HO2S sensor (contamination from the use of silicone-based cleaners and sealants, leaded fuel, excessive oil consumption, etc.) �· Deteriorating HO2S sensor
