Diagnostic Aids
WARNING: This page is about a different variant/trim than selected.
- A steady or intermittent high resistance of 15 Ω or greater on the ignition voltage circuit will cause the MAF sensor signal to be increased by as much as 60 g/s.
- Depending on the current ambient temperature, and the vehicle operating conditions, a MAF sensor signal circuit that is shorted to the IAT signal circuit will cause the MAF sensor signal to be skewed or erratic. Additionally it may cause a rapid fluctuation in the IAT Sensor parameter.
- Use a solution of dish soap and water in a spray bottle to pinpoint any suspected air leaks in the induction system. This includes vacuum lines, positive crankcase ventilation system, intake manifold, throttle body, charge air cooler assembly.
