P0122-TPS/APP CIRCUIT LOW
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
Due to the integration of the Powertrain and Transmission Control Modulesthe New Generation Control Module III
will be referred to as the Powertrain Control Module (PCM). The 3–wire TPS (4.7L V-8 Engine) provides the PCM
with an input signal voltage that represents the throttle blade position of the throttle body. The Throttle Position
Sensor (TPS) is connected to the throttle blade shaft. As the position of the throttle blade changes, the output volt-
age of the TPS changes.
The PCM supplies approximately 5.0 volts to the TPS. The TPS output voltage(input signal to the PCM) represents
the throttle blade position. The PCM receives an input signal voltage fromthe TPS. This will vary in an approximate
range from 0.26 volts at minimum throttle opening (idle), to 4.49 volts at maximum opening (wide open throttle).
The Accelerator Pedal Position Sensor (APPS) is currently used only with the 5.7L V-8 engine. The APPS is a linear
potentiometer. It provides the PCM with a voltage signal proportional to the angle, or position of the accelerator
pedal. The APPS signal along with inputs from other sensors is used by the PCM to calculate the throttle plate
position.
A mechanical cable is used between the accelerator pedal and the APPS assembly. Although a cable is used
between the accelerator pedal and the APPS assembly, a mechanical cable isnot used between the accelerator
pedal and the throttle body. The throttle plate position is electronically controlled by the PCM.
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

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Diagnostic Test
1.CHECK IF RELATED ENGINE TPS/APPS DTC’S ARE PRESENT
With the scan tool, check Engine DTC’s.
Are there any Engine TPS/APPS DTCs present?
Ye s>>
Refer to the Driveability Category and perform the appropriate Symptom.
No>>

2.CHECK TO SEE IF 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 DTC EVENT DATA information, a BATTERY DISCONNECT must be performed. Performing a
BATTERY DISCONNECT may reset learned Transmission values to controller defaults 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.
