SYMPTOM
P0122 - THROTTLE POSITION SENSOR VOLTAGE LOW
WHEN MONITORED
With the ignition ON and battery voltage above 10.4 volts.
SET CONDITION
Throttle Position Sensor voltage at the PCM is 0.1 volt for 1.3 seconds.
POSSIBLE CAUSES
- TPS voltage change not smooth
- TPS 5 volt supply circuit open
- TPS connectors/harness intermittent problem (D)
- TPS harness/connectors intermittent problem (C)
- TPS harness/connectors observable problem
- TPS signal circuit shorted to ground
- TPS signal circuit shorted to sensor ground circuit
- Throttle position sensor (voltage > 1.0 volt with throttle closed)
- Transmission control module
- Powertrain Control Module
