P0122

Tests 1 - 2:

Tests 3 - 7:

Tests 8 - 13:

SYMPTOM
P0122 - THROTTLE POSITION SENSOR VOLTAGE TOO 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
- TRANS control module
- TPS voltage change not smooth
- TPS connectors/harness intermittent (D)
- TPS harness/connectors intermittent (C)
- TPS harness/connectors observable (E)
- TPS 5 volt supply circuit open
- TPS 5 volt supply circuit shorted to ground
- TPS signal circuit shorted to ground
- TPS signal circuit shorted to sensor ground circuit
- Throttle position sensor (voltage > 1.0 volt)
- Powertrain control module
