TEST ACTION APPLICABILITY
3 With the DRBIIIt, record the EATX EVENT DATA to help identify the conditions in
which the DTC was set.
With the DRBIIIt, erase Transmission DTCs.
NOTE: To erase EATX EVENT DATAinformation, a BATTERY DISCONNECT
must be performed. Performing a BATTERY DISCONNECT will reset all
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 EATX EVENT DATA.
With the DRBIIIt, read Transmission DTCs.
Did the DTC P0122 THROTTLE POSITION SENSOR LOW, reset?
All
Yes → Go To 4
No → Go To 5
4 NOTE: Due to the integration of the Powertrain and Transmission Control
Modules, bus communication between the modules is internal.
Using the schematics as a guide, inspect the wiring and connectors. Repair as
necessary. Pay particular attention to all power and ground circuits.
If there are no possible causes remaining, view repair.

Replace the Powertrain Control Module per the Service Informa-
tion. WITH THE DRBIIIt PERFORM QUICK LEARN.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -

5 The conditions necessary to set this DTC are not present at this time.
Using the schematics as a guide, inspect the wiring and connectors specific to this
circuit.
Wiggle the wires while checking for shorted and open circuits.
Pay particular attention to the TPS signal and sensor ground circuits.
With the DRBIIIt, check the EATX EVENT DATA to help identify the conditions in
which the DTC was set.
Were there any problems found?
All
Yes → Repair as necessary.
Perform 41TE (NGC) TRANSMISSION VERIFICATION TEST -
