DTC P0223:00 [MZR 2.0 DISI]

id0102f5702900

DTC P0223:00

TP sensor No.2 circuit high input

DETECTION CONDITION

•  If the PCM detects that the TP sensor No.2 voltage is above 4.85 V after the ignition is switched to ON, the PCM determines that the TP sensor No.2 circuit has a malfunction.

Diagnostic support note

•  This is a continuous monitor (CCM).

•  The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA (Mode 2)/Snapshot data is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  Throttle body connector or terminals malfunction

•  PCM connector or terminals malfunction

•  Short to power supply in wiring harness between throttle body terminal D and PCM terminal 2AL

•  TP sensor No.2 power supply circuit and signal circuit are shorted to each other

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

•  TP sensor No.2 malfunction

•  PCM malfunction

DTC P0223:00	TP sensor No.2 circuit high input
DETECTION CONDITION	• If the PCM detects that the TP sensor No.2 voltage is above 4.85 V after the ignition is switched to ON, the PCM determines that the TP sensor No.2 circuit has a malfunction. Diagnostic support note • This is a continuous monitor (CCM). • The MIL illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA (Mode 2)/Snapshot data is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• Throttle body connector or terminals malfunction • PCM connector or terminals malfunction • Short to power supply in wiring harness between throttle body terminal D and PCM terminal 2AL • TP sensor No.2 power supply circuit and signal circuit are shorted to each other • Open circuit in wiring harness between throttle body terminal C and PCM terminal 2AJ • TP sensor No.2 malfunction • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot 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 THROTTLE BODY CONNECTOR CONDITION • Switch the ignition to 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 connector and/or terminals, then go to Step 9.
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 9.
4		No	Go to the next step.
5	INSPECT TP SENSOR NO.2 SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Throttle body and PCM connectors are disconnected. • Switch the ignition to ON (engine off). • Measure the voltage at the throttle body terminal D (wiring harness-side). • Is there any voltage?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 9.
5		No	Go to the next step.
6	INSPECT TP SENSOR NO.2 POWER SUPPLY CIRCUIT AND SIGNAL CIRCUIT FOR SHORT TO EACH OTHER • Throttle body and PCM connectors are disconnected. • Switch the ignition to off. • Inspect for continuity between throttle body terminals E and D (wiring harness-side). • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to each other, then go to Step 9.
6		No	Go to the next step.
7	INSPECT TP SENSOR NO.2 GROUND CIRCUIT FOR OPEN CIRCUIT • Throttle body and PCM connectors are disconnected. • Inspect for continuity between throttle body terminal C (wiring harness-side) and PCM terminal 2AJ (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible open circuit, then go to Step 9.
8	INSPECT TP SENSOR NO.2 • Reconnect all disconnected connectors. • Inspect the TP sensor No.2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [MZR 2.0 DISI].) • Is there any malfunction?	Yes	Replace the TP sensor, then go to the next step. (See THROTTLE POSITION (TP) SENSOR REMOVAL/INSTALLATION [MZR 2.0 DISI].)
8		No	Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI].) • Start the engine and warm it up completely. • Perform the KOEO or KOER self test. (See KOEO/KOER SELF TEST [MZR 2.0 DISI].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR 2.0 DISI].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [MZR 2.0 DISI].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR 2.0 DISI].)
10		No	DTC troubleshooting completed.
