P0122-TPS/APP CIRCUIT LOW
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
This DTC will set if the monitored TPS voltage drops below .078 volts for theperiod of 0.48 seconds.
Possible Causes
RELATED TPS ENGINE DTCS PRESENT
POWERTRAIN CONTROL MODULE
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)
Theory of Operation
The powertrain controller receives the throttle position signal from theThrottle Position Sensor (TPS). The controller
provides the TPS with a 5 volt pull up and a sensor ground. The signal is checked for being out of range as well
as for intermittent operation (excessive signal changes). The engine controller transmits the throttle value onto the
Bus. Most engine controllers will calculate the throttle value if the throttle signal is lost. If an error is detected by the
transmission controller and the throttle value is available on the Bus, the Bus value will be used, normal operation
will continue, and a TPS code will be set. If an error is detected and the throttle value is not available on the Bus,
normal operation will be discontinued, a TPS DTC will be set, and the MIL will be turned on after 5 minutes of
calculated operation.
