Hello members,

A couple weeks ago I noticed a sudden drop in my gas mileage. I was about to check the e-brake when I got the above code, P0105.

I ran ODB-II real-time tests and here are those results:

TID: $0a CID:$11
TID: $22 CID:$11
TID: $04 CID:$11 (this one is new)
(Pretty sure some of that isn't needed)

I have replaced all O2 sensors except the one closest to the passenger firewall, which requires a special tool - I guess - cuz I can't get to it - for now.

My question: Should I start by replacing the MAS? Any other considerations?

Thank you members.
Chris

 

The code indicates a bad MAP sensor or a bad wire between the sensor and the ECM. See the attached info. I would first check the wires but most likely the sensor is bad.
