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.
Diagnostic Test
1.DETERMINING IF RELATED ENGINE TPS DTCS ARE PRESENT
With the scan tool, check Engine DTCs, including pending DTCs and one trip failures.
Are there any Engine TPS DTCs present?
Ye s>>
Refer to the Driveability category and perform the appropriate diagnostic procedure.
Perform 42RLE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21 - TRANSMISSION/
TRANSAXLE/AUTOMATIC - 42RLE - STANDARD PROCEDURE)

2.CHECK IF THE DTC IS CURRENT
With the scan tool, record the DTC EVENT DATA to help identify the conditionsinwhichtheDTCwasset.
With the scan tool, erase Transmission DTCs.
NOTE: To erase EVENT DATA information, a BATTERY DISCONNECT must be performed. Performing a BAT-
TERY DISCONNECT will reset all learned Transmission values to controllerdefaults which may lead to
erratic shift schedules.
Drive the vehicle and try to duplicate the conditions in which the DTC was reported by the DTC EVENT DATA.
With the scan tool, read Transmission DTCs.
Does this DTC reset?
Ye s>>
Using the schematics as a guide, check the Powertrain Control Module (PCM)terminals for corrosion,
damage, or terminal push out. Pay particular attention to all power and ground circuits. Check for Ser-
vice Information Tune-ups or Service Bulletins for any possible causes that may apply. If no problems
are found, replace the PCM per the Service Information. With the scan tool,perform QUICK LEARN.
