DTC P0222 [L8, LF, L3]

id0102a1806000

DTC P0222 | TP sensor No.2 circuit low input
--- | ---
DETECTION CONDITION | • If PCM detects TP sensor No.2 voltage is to be below 0.2 V after the ignition switch to the ON position, the PCM determines that TP circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA is available. • Are any DTCs is stored in the PCM memory.
POSSIBLE CAUSE | • TP sensor No.2 malfunction • Connector or terminal malfunction • Open circuit in wiring harness between throttle body terminal B and PCM terminal 2AO • Short to ground in wiring harness between throttle body terminal B and PCM terminal 2AO • Open circuit in wiring harness between throttle body terminal C and PCM terminal 2AL • Short to ground in wiring harness between throttle body terminal C and PCM terminal 2AL • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY FREEZE FRAME DATA AND DIAGNOSTIC MONITORING TEST RESULTS HAS BEEN RECORDED • Has FREEZE FRAME DATA been recorded? | Yes | Go to the next step.
No | Record the FREEZE FRAME on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR 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 CONNECTOR FOR POOR CONNECTION • Turn the ignition switch off. • Disconnect the throttle body 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 8.
No | Go to the next step.
4 | INSPECT TP SENSOR NO.2 CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the following circuits: - Throttle body terminal B (wiring harness-side) and body ground - Throttle body terminal C (wiring harness-side) and body ground • Is there continuity? | Yes | Repair or replace the wiring harness for a possible short to ground, then go to Step 8.
No | Go to the next step.
5 | INSPECT TP SENSOR NO.2 • Inspect TP sensor No.2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [L8, LF, L3].) • Is there any malfunction? | Yes | Replace the throttle body, then go to Step 8. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].)
No | Go to the next step.
6 | 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 8.
No | Go to the next step.
7 | INSPECT TP SENSOR NO.2 CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between the following terminals: - Throttle body terminal B (wiring harness-side) and PCM terminal 2AO (wiring harness-side) - Throttle body terminal C (wiring harness-side) and PCM terminal 2AL (wiring harness-side) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness for a possible an open circuit, then go to the next step.
8 | VERIFY TROUBLESHOOTING OF DTC P0222 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 same DTC present? | Yes | Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L3].)
No | Go to the next step.
9 | VERIFY AFTER REPAIR PROCEDURE • Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [L8, LF, L3].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L3].)
No | DTC troubleshooting completed.
