P2099-DOWNSTREAM FUEL TRIM SYSTEM 2 RICH
For a complete wiring diagramRefer to Section 8W.

P2100-ELECTRONIC THROTTLE CONTROL MOTOR CIRCUIT
For a complete wiring diagramRefer to Section 8W.

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.
Is the DTC active at this time?

No>>
Refer to the INTERMITTENT CONDITION Diagnostic Procedure.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
2.THROTTLE PLATE INSPECTION
Turn the ignition off.
Remove the Air Cleaner Assembly from the Throttle Body.
Check for any signs of a foreign material (ice or dirt) on the Throttle Plateor in the bore causing the Throttle Plate
to stick.
Manually open and close the throttle plate using your hands.
Does the Throttle Plate move?
Ye s>>
Go To 3
No>>
Remove the debris if possible or replace the Throttle Body Assembly. Disconnect the Battery when
replacing the Throttle Body Assembly. After installation is complete, use a scan tool and select the ETC
RELEARN function.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

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?
Ye s>>
Replace and reprogram the Powertrain Control Module per Service Information.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No>>

P2108-ELECTRONIC THROTTLE CONTROL MODULE PERFORMANCE
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on.
Set Condition:
Internal PCM failure. Customer may experience an extended cranking condition with limited driving and a
rough idle. One trip fault and the code will set within 5 seconds. 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: 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>>
Replace and reprogram the Powertrain Control Module per Service Information.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)

P2115-ACCELERATOR PEDAL POSITION SENSOR 1 MINIMUM STOP
PERFORMANCE
For a complete wiring diagramRefer to Section 8W.
When Monitored:
Ignition on. During in plant mode the APP Sensors need to be checked to make sure that idle and full pedal
travel can be reached on both sensors. The test for P2115 is only enabled once test for P2166 has passed.
Set Condition:
APPS No.1 has failed to achieve the required minimum value during In Plant testing. One trip fault and the
code will set within 5 seconds. Engine will only idle.
Possible Causes
IN PLANT TEST FAILURE
