P0123-TPS/APP CIRCUIT HIGH
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 as the Powertrain Control Module (PCM). The 4.7L V-8 Throttle Positioning Sensor (TPS) provides
the PCM with an input signal voltage that represents the throttle blade position of the throttle body. The TPS is
connected to the throttle blade shaft. As the position of the throttle blade changes, the output voltage of the TPS
changes.
The 5.7L V-8 Accelerator Pedal Position Sensor (APPS) is a linear potentiometer that 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 which is electronically controlled.
When Monitored:
Continuously with the ignition on and engine running.
Set Condition:
This DTC will set if the monitored TPS voltage rises above 4.94 volts for theperiod of 0.48 seconds.
Possible Causes
RELATED ENGINE TPS/APPS DTC’S PRESENT

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 21 - TRANSMIS-
SION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Diagnostic Test
1.DETERMINING IF RELATED ENGINE TPS/APPS DTCS ARE PRESENT
With the scan tool, check Engine DTCs, this includes all one trip failures.
Are there any Engine TPS/APPS DTCs present?

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 DTC EVENT DATA information, a BATTERY DISCONNECT must be performed. Performing a
BATTERY DISCONNECT may reset all learned Transmission values to controller defaults that could lead to
an inconsistent shift schedule.
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.

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. If no problems
are found, replace the PCM per the Service Information. With the scan tool,perform QUICK LEARN.
Perform 45RFE/545RFE TRANSMISSION VERIFICATION TEST - VER 1. (Refer to 21- TRANSMIS-

This DTC will set if the monitored TPS throttle angle between the angles of 6° and 120° and the degree
change is greater than 5° within a period of less than 7.0 msec.

With the scan tool, erase Transmission DTCs.
NOTE: To erase EVENT DATA information, a BATTERY DISCONNECT must be performed. Performing a BAT-
TERY DISCONNECT may reset all learned transmission values to controller default. This may lead to erratic
shift schedules.

DODGE RAM SRT-10 2006 Service Repair Manual When Monitored:
With the engine running and the PCM has closed the Transmission Control Relay.
Set Condition:
If the battery voltage of the Transmission Output circuit(s) to the PCM is less than 10.0

When Monitored:
With the engine running and the PCM has closed the Transmission Control Relay.
Set Condition:
If the battery voltage of the Transmission Output circuit(s) to the PCM is less than 10.0 volts for the period of
15 seconds. Note: P0562 generally indicates a gradually falling battery voltage or a resistive connection(s) to
the PCM. The DTC will also set if the battery voltage sensed at the PCM is lessthan 6.5-volts for 200ms or
where the Transmission Output circuits are less than 7.2-volts for 200ms.
Possible Causes
RELATED CHARGING SYSTEM DTC’S
(Z904, Z908, Z977) GROUND CIRCUITS OPEN OR HIGH RESISTANCE
(T16) TIPM OUTPUT CIRCUIT OPEN OR HIGH RESISTANCE
TOTALLY INTEGRATED POWER MODULE (TIPM)
POWERTRAIN CONTROL MODULE
Always perform the 45RFE/545RFE Pre-Diagnostic Troubleshooting Procedure before proceeding. (Refer to
21 - TRANSMISSION/TRANSAXLE/AUTOMATIC - 45RFE/545RFE - STANDARD PROCEDURE)
Theory of Operation
Friction element distress could result from an insufficient supply voltage to properly control the solenoids. To prevent
this possibility, the battery voltage is monitored and the system is placed in logical limp-in if the battery voltage
drops below the limit.
Diagnostic Test
