My Aeroforce gauge was incorrectly reporting a P0121 (throttle body code) so I was chasing that for a little while until I finally got HP Tuners and figured out that the code was actually P012C, which applies to the sensor in the snout. I did a log with key on/engine off and the sensor is reading 0 psi/0 volts. I'm guessing it should match the lid MAP and be close to atmosphere (14.7psi)? Sounds like I need to start tracing wires if so, FML. Anyone else ever had this code?
