DTC P2008 | APV motor control circuit/open
--- | ---
DETECTION CONDITION | • The PCM monitors the APV motor control current when the engine is running. If the control current is less than 0.1 A or more than 10 A, the PCM determines that there is an APV motor control open circuit. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. • PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE | • APV motor malfunction • Connector or terminal malfunction • Open circuit in wiring harness between APV motor terminal D and PCM terminal 3G • Short to power supply in wiring harness between APV motor terminal D and PCM terminal 3G • Short to GND in wiring harness between APV motor terminal D and PCM terminal 3G • Open circuit in wiring harness between APV motor terminal B and PCM terminal 3J • Short to power supply in wiring harness between APV motor terminal B and PCM terminal 3J • Short to GND in wiring harness between APV motor terminal B and PCM terminal 3J • 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 the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service repair information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
No | Go to the next step.
3 | INSPECT APV MOTOR CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the APV motor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 9.
No | Go to the next step.
4 | INSPECT APV MOTOR CIRCUIT FOR SHORT TO GND • Turn the ignition switch off. • Inspect for continuity between the following circuits: – APV motor terminal D (wiring harness-side) and body GND – APV motor terminal B (wiring harness-side) and body GND • Is there continuity? | Yes | Repair or replace the wiring harness for a possible short to GND, then go to Step 9.
No | Go to the next step.
5 | INSPECT APV MOTOR CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (Engine off). • Measure the voltage between the following circuits: – APV motor terminal D (wiring harness-side) and body GND – APV motor terminal B (wiring harness-side) and body GND • Is the voltage B+? | Yes | Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
No | Go to the next step.
6 | INSPECT APV MOTOR • Inspect the APV motor. (See AUXILIARY PORT VALVE (APV) MOTOR INSPECTION (13B-MSP (HIGH POWER)).) • Is there any malfunction? | Yes | Replace the APV motor, then go to Step 9. (See INTAKE MANIFOLD DISASSEMBLY/ASSEMBLY.)
No | Go to the next step.
7 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 9.
No | Go to the next step.
8 | INSPECT APV MOTOR CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between the following circuits: – APV motor terminal D (wiring harness-side) and PCM terminal 3G (wiring harness-side) – APV motor terminal B (wiring harness-side) and PCM terminal 3J (wiring harness-side) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P2008 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the PENDING CODE same as DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE.) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE.)
No | DTC troubleshooting completed.
