id0102d2707800

DTC P2107:00 | Throttle actuator control module processor
--- | ---
DETECTION CONDITION | • The throttle actuator control area of the PCM failed the self-test.
POSSIBLE CAUSE | • Throttle body connector or terminal malfunction • PCM connector or terminal malfunction • 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 • Short to ground between throttle actuator terminal A and PCM terminal 2BO • Short to ground between throttle actuator terminal B and PCM terminal 2BR • Short to TP sensor power supply between throttle actuator terminal A and PCM terminal 2BO • Short to TP sensor power supply between throttle actuator terminal B and PCM terminal 2BR • Throttle actuator control circuits are shorted each other • Throttle body malfunction • 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.
No | Record 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.
No | Go to the next step.
3 | INSPECT THROTTLE BODY AND PCM CONNECTORS FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the throttle body and PCM connectors. • 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.
No | Go to the next step.
4 | INSPECT THROTTLE ACTUATOR CONTROL CIRCUIT FOR SHORT TO POWER SUPPLY • Throttle body and PCM connectors are disconnected. • 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.
No | Go to the next step.
5 | INSPECT THROTTLE ACTUATOR CONTROL CIRCUIT FOR SHORT TO GROUND OR ETCREF/ETCRTN CIRCUIT • Throttle body and PCM connectors are disconnected. • Turn the ignition switch off. • Measure resistance between the following circuits: ― Throttle actuator terminal A (wiring harness-side) and body ground ― Throttle actuator terminal A and D (wiring harness-side) ― Throttle actuator terminal A and E (wiring harness-side) ― Throttle actuator terminal B (wiring harness-side) and body ground ― Throttle actuator terminal B and D (wiring harness-side) ― Throttle actuator terminal B and E (wiring harness-side) • Is the resistance greater than 10 kilohms? | Yes | Go to the next step.
No | Repair for a short circuit, then go to Step 8.
6 | INSPECT THROTTLE ACTUATOR CONTROL CIRCUITS FOR SHORT EACH OTHER • Throttle body and PCM connectors are disconnected. • Turn the ignition switch off. • Measure resistance between throttle actuator terminal A and B. • Is the resistance more than 10 kilohms? | Yes | Go to the next step.
No | Repair or replace suspected part, then go to Step 8.
7 | 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].)
No | Go to the next step. (The system is operating normally at this time. The concern may have been caused by a loose or corroded connector.)
8 | VERIFY TROUBLESHOOTING OF DTC P2107:00 HAS BEEN COMPLETED • Verify that all disconnected connectors reconnected. • Start the engine. • Clear DTC from PCM memory using M-MDS. • Start the engine and run it at idle. • Retrieve the DTC using the M-MDS. • Is same DTC present? | Yes | Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [MZI-3.7].) Go to the next step.
No | Go to the next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZI-3.7].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZI-3.7].)
No | Troubleshooting completed.
