SYMPTOM
P0129-BAROMETRIC PRESSURE OUT-OF-RANGE

WHEN MONITORED
With the ignition key on. Engine speed at less than 250 RPM.

SET CONDITION
The PCM senses the voltage from the MAP sensor to be greater than 4.9 volts (2.4 volts for Turbo) or below 2.28 volts (1.2 volts for Turbo) for 400 milliseconds. Two Trip Fault.

POSSIBLE CAUSES
- IAC signal circuit low
- IAC signal circuit high
- Intermittent condition
- (K7) 5 volt supply circuit shorted to voltage
- (K7) 5 volt supply circuit shorted to ground
- MAP sensor internal open
- (K7) 5 volt supply circuit open
- (K1) MAP signal circuit open
- (K1) MAP signal circuit shorted to ground
- PCM (K7) 5 volt supply circuit
- PCM (K1) MAP signal
