id0102e3811400

DTC P2107

Throttle actuator control module processor

DETECTION CONDITION

•  The throttle actuator control area of the PCM failed the self-test.

POSSIBLE CAUSE

•  MAF sensor connector or terminal malfunction

•  Throttle body malfunction

•  Throttle actuator control circuits are shorted each other

•  Short to power supply between throttle actuator terminal A and PCM terminal 2BO

•  Short to power supply between throttle actuator terminal B and PCM terminal 2BR

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT MAF SENSOR CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the MAF/IAT sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 8.
3		No	Go to the next step.
4	INSPECT THROTTLE ACTUATOR CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure voltage between the following circuits: ― Throttle actuator terminal A (wiring harness-side) and body ground. ― Throttle actuator terminal B (wiring harness-side) and body ground. • Are there voltage B+?	Yes	Repair or replace suspected part, then go to Step 8.
4		No	Go to the next step.
5	INSPECT THROTTLE ACTUATOR CONTROL CIRCUITS FOR SHORT EACH OTHER • Turn the ignition switch off. • Disconnect the throttle body and PCM connector. • Measure resistance between throttle actuator terminal A and B. • Is the resistance more than 10 kilohms?	Yes	Go to the next step.
5		No	Repair or replace suspected part, then go to Step 8.
6	INSPECT THROTTLE ACTUATOR • Inspect the throttle actuator. (See THROTTLE BODY INSPECTION [MZI-3.7].) • Is there any malfunction?	Yes	Replace the throttle body, then go to Step 8. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)
6		No	Go to the next step.
7	INSPECT FOR CORRECT PCM OPERATION • Disconnect all the PCM connectors. • Visually inspect for: ― Pushed out pins ― Corrosion • Connect all the PCM connectors and verify that they seat correctly. • Retrieve DTCs using the M-MDS. • Is the PENDING CODE for this DTC present?	Yes	Go to the next step.
7		No	The system is correctly. Go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P2107 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Start the engine. • Clear DTC from PCM memory using the M-MDS. • Perform the “KOEO/KOER Self-Test”. (See KOEO/KOER SELF TEST [MZI-3.7 (PCM CONNECTOR (2 TYPES))].) • Is same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZI-3.7].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7 (PCM CONNECTOR (2 TYPES))].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7 (PCM CONNECTOR (2 TYPES))].)
9		No	Troubleshooting completed.
