DETECTION CONDITION

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

POSSIBLE CAUSE

•  Connector or terminal malfunction

•  Open circuit wiring harness between throttle body terminal C and PCM terminal 2AL

•  TP sensor No.2 malfunction

•  TP sensor signal circuits are shorted each other

DTC P0223:00	TP sensor No.2 circuit high input
DETECTION CONDITION	• The TP sensor No.2 circuit was flagged as a concern by the PCM indicating a high voltage.
POSSIBLE CAUSE	• Connector or terminal malfunction • Open circuit wiring harness between throttle body terminal C and PCM terminal 2AL • TP sensor No.2 malfunction • TP sensor signal circuits are shorted each other

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 8.
3		No	Go to the next step.
4	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 8.
4		No	Go to the next step.
5	INSPECT TP SIGNAL CIRCUIT FOR OPEN CIRCUIT • Throttle body and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between the following terminals: ― Throttle body terminal C (wiring harness-side) and PCM terminal 2AL (wiring harness-side) ― Throttle body terminal D (wiring harness-side) and PCM terminal 2AP (wiring harness-side) • Are there continuity?	Yes	Go to the next step.
5		No	Repair or replace suspected part, then go to Step 8.
6	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 Step 8.
6		No	Go to the next step.
7	INSPECT TP SENSOR SIGNAL CIRCUITS FOR SHORT EACH OTHER • Throttle body and PCM connectors are disconnected. • Measure resistance between throttle body connector terminal D and C. • Is the resistance more than 10 kilohms?	Yes	Go to the next step.
7		No	Repair or replace suspected part, then go to Step 8.
8	VERIFY TROUBLESHOOTING OF DTC P0223:00 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 or KOER self-test. (See KOEO/KOER SELF TEST [MZI-3.7].) • 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.
8		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].)
9		No	Troubleshooting completed.
