P2101-ELECTRONIC THROTTLE CONTROL MOTOR PERFORMANCE
For a complete wiring diagramRefer to Section 8W.
When Monitored:
With the vehicle running, ETC Motor not in Limp Home mode, and the TPS adaptation is complete.
Set Condition:
The PCM recognizes too large of an error between the actual position of the Throttle Plate and the Set Point
position. One trip fault and the code will set within 5 seconds. Three good trips to turn off the MIL ETC light is
flashing.
Possible Causes
THROTTLE BODY ASSEMBLY
LOW BATTERY VOLTAGE
PCM
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.ACTIVE DTC
NOTE: Before continuing visually inspect the throttle blade and bore for any obstructions. Icing of the throt-
tlebodymayhavecausedthiscodetoset.
NOTE: Low battery voltage can also cause excessive current draw, in very hot and very cold ambient tem-
perature. Make sure the battery can pass a Load test before continuing.
NOTE: Diagnose any 5-Volt Supply, Battery, and TP Sensor DTCs before continuing.
Ignition on, engine not running.
With a scan tool, read DTCs.

P2107-ELECTRONIC THROTTLE CONTROL MODULE PROCESSOR
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on.
Set Condition:
Internal PCM failure. Module will attempt to reset, so you will be able to hear the throttle relearning. If the
condition is continuous, the vehicle may not be driveable. One trip fault.ETC light is flashing.
Possible Causes
POWERTRAIN CONTROL MODULE NEEDS TO BE REPROGRAMMED
Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to 9 - ENGINE -
DIAGNOSIS AND TESTING).
Diagnostic Test
1.REPROGRAM THE POWERTRAIN CONTROL MODULE
Check for any related TSBs.
Verify the PCM is at the latest calibration (flash level).
NOTE: An intermittent loss of power to the PCM without performing an ETC Relearn procedure may cause
this DTC to set.
Flash the Powertrain Control Module per Service Information if any updates are available.
Start the engine.
Allow the engine to reach normal operating temperature.
Operate the accelerator pedal. (do not exceed 3500 rpm)
Test drive the vehicle for 10 miles on a flat road surface.
Does this DTC reset?

DIAGNOSIS AND TESTING).
Diagnostic Test
1.REPROGRAM THE POWERTRAIN CONTROL MODULE
Check for any related TSBs.
Verify the PCM is at the latest calibration (flash level).
NOTE: Inspect the Intake Manifold components for vacuum leaks, repair as necessary
NOTE: An intermittent loss of power to the PCM without performing an ETC Relearn procedure may cause
this DTC to set.
NOTE: Diagnose any other DTCs that may have set with the P2108.
Flash the Powertrain Control Module per Service Information if any updates are available.
Start the engine.
Allow the engine to reach normal operating temperature.
Operate the accelerator pedal. (do not exceed 3500 rpm)
Test drive the vehicle for 10 miles on a flat road surface.
Does this DTC reset by itself?
Ye s>>
