Hi all,
After doing an ecu check and now seeing this fault code P0108: MAP/Barometric Pressure Sensor Too High. Not sure what is sensor too high. Normal error is either related to voltage or circuit high input. The problem still exists despite the replacement of the MAP and MAF sensors. Now, I'm unsure of what to do. Need help

p/s: current barometric reading is 99kpa
Thanks

 

As you already replaced the MAF with a known good one, the most likely cause for this code to be set is an open barometric pressure sensor circuit. This could be anything from connector damage on pin 2 of the MAF connector, broken or damaged wiring between it and the ECU, or damage to ECU pin 85 (Evo 8) or pin 51 (Evo 9).

 

Hello,
I really appreciate your information. I will inspect the MAF and ECU wiring and pins. Will test the voltage continuity, and report back my findings.
Many thanks
