Does any one know how to check the output from an oxygen sensor?
Before heading for the dealer, I wanted to check if either sensor was
bad. A replacement sensor is about $125.00 each, internet price. Too
pricey to just replace doing the trial and error method. Its a 99 Passat
20 valve turbo 4 cyl. The check engine light code came up "manufacture
air fuel metering control" It has been running fine till 2 days ago.
It stalled braking for a stop light twice. Any help would be
appreciated.
Thanks, Jerry
