Anyone know how to test a MAS mass flow air sensor ?
I replaced my MASS last month - 1) it has not adjusted the computer after 3 weeks or. 2) Has not cured my problem because it is defective.3) its not my problem.
I keep getting codes suggesting the MAS. There is an Ebay seller that says he is a Mercedes Tech and sells used ones that are tested and referbished. I asked him if referbished means "cleaned". He wrote he has a process where he brings them back to specifications. I asked him again, " So you clean them ? " He did not reply to my 2nd question. I may have wasted some more money ordering a tested used one..should be here this week. I have analog and digital electric test meters. Anyone know what to check on a MAS ? Last week I checked my ignition wires on one bank but still do not know what specification they should be . if anyone knows that would help me rule out the wires. Replaced plugs two times in 10,000 miles and new cats. Not hitting on 6 in Michigan. steve
