Re: Error Code 34 help
I bought my car from the original owner with all receipts from day 1. This code was on about 6 of them. The maf was replaced twice and ecu was replaced once. I still had the code for a while. I checked all the wires continuity test from ecu to sensor and checked the burnoff relay. then i backprobed the maf to see the readings at idle and if they increased. I beleive it was around a half volt at idle and increased with throttle. Everything was good from my view so I priced a new sensor anyway but never replaced it since it is around 300. Now I havent had the code in a couple years.
I had read online somewhere that the manufactures of the maf sensor had the wrong blueprints and did not agree with the ecu. who knows how tru this is.
I would like to hear if anyone else has chased this code before?
