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 0.2 volt for 0.7 seconds.

POSSIBLE CAUSES
- TPS voltage change not smooth
- TPS connectors/harness intermittent defect (D)
- TPS harness/connectors intermittent defect (C)
- TPS harness/connectors observable defect (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 defective (voltage > 1.0 volt)
- Powertrain control module defective
