P1192

Test 1 - 3:

Test 4 - 5:

SYMPTOM
P1192-INLET AIR TEMP SENSOR VOLTAGE LOW

WHEN MONITORED
With the ignition on and battery voltage greater than 10.4 volts.

SET CONDITION
The Inlet Air Temperature (IAT) sensor circuit voltage at the PCM goes below 0.8 volt.

POSSIBLE CAUSES
- IAT sensor voltage below 1.0 volt
- IAT sensor internal failure
- (K21) IAT sensor signal circuit shorted to ground
- (K21) IAT sensor signal shorted to (K4) sensor ground circuit
- PCM
