DTC P0222

TP sensor No.2 circuit low input

DETECTION CONDITION

•  The TP sensor No.2 circuit was flagged as a concern by the PCM indicating a low voltage or open circuit.

POSSIBLE CAUSE

•  TP sensor No.2 malfunction

•  Connector or terminal malfunction

•  Open circuit between throttle body terminal C and PCM terminal 2AD

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 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 TP SENSOR 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). • Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 9.
3		No	Go to the next step.
4	INSPECT TP SENSOR CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch to the ON position (Engine off). • Inspect for continuity between the following circuits: ― TP sensor terminal D (wiring harness-side) and body ground ― TP sensor terminal C (wiring harness-side) and body ground • Are there continuity?	Yes	Repair or replace suspected part, then go to Step 9.
4		No	Go to the next step.
5	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). • Are there any malfunction?	Yes	Repair or replace suspected part, then go to Step 9.
5		No	Go to the next step.
6	INSPECT TP SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between throttle body connector terminal C (wiring harness-side) and PCM terminal 2AD (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
6		No	Repair or replace suspected part, then go to Step 9.
7	INSPECT TP GROUND CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Verify the continuity between TP sensor terminal E and body ground. • Is the continuity?	Yes	Go to the next step.
7		No	Repair or replace suspected part, then go to Step 9.
8	INSPECT TP SENSOR NO.2 • Inspect the TP sensor No.2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [MZI-3.7].) • Is there any malfunction?	Yes	Replace the throttle body, then go to the next step.
8		No	Go to the next step.
9	VERIFY TROUBLESHOOTING OF DTC P0222 HAS BEEN COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • 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].)
9		No	Go to the next step.
10	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. (SeeDTC TABLE [MZI-3.7 (PCM CONNECTOR (2 TYPES))].)
10		No	Troubleshooting completed.
