DTC P0223:00 [L8, LF, L5]

id010242702900

DTC P0223:00

TP sensor No.2 circuit high input

DETECTION CONDITION

•  If the PCM detects the TP sensor No.2 voltage is to be above 4.85 V after switch the ignition to ON, the PCM determines that the 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.

•  FREEZE FRAME DATA is available.

•  The DTC is stored in the PCM memory.

POSSIBLE CAUSE

•  TP sensor No.2 malfunction

•  Connector or terminal malfunction

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

•  Open circuit in wiring harness between throttle body terminal D and PCM terminal 2AP

•  PCM malfunction

DTC P0223:00	TP sensor No.2 circuit high input
DETECTION CONDITION	• If the PCM detects the TP sensor No.2 voltage is to be above 4.85 V after switch the ignition to ON, the PCM determines that the 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. • FREEZE FRAME DATA is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• TP sensor No.2 malfunction • Connector or terminal malfunction • Short to power supply in wiring harness between throttle body terminal C and PCM terminal 2AL • Open circuit in wiring harness between throttle body terminal D and PCM terminal 2AP • 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.
1		No	Record the FREEZE FRAME 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 POOR CONNECTION OF THROTTLE BODY CONNECTOR • 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 terminal and/or connector, then go to Step 8.
3		No	Go to the next step.
4	INSPECT TP SENSOR NO.2 SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Switch the ignition to ON (Engine off). • Measure the voltage between throttle body terminal C (wiring harness-side) and body ground. • Is the voltage B+?	Yes	Repair or replace the wiring harness for a possible short to power supply, then go to Step 8.
4		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, L5].) • Is there any malfunction?	Yes	Replace the throttle body, then go to Step 8. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L5].)
5		No	Go to the next step.
6	INSPECT POOR CONNECTION OF PCM CONNECTOR • Switch the ignition to 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 and/or connector, then go to Step 8.
6		No	Go to the next step.
7	INSPECT TP SENSOR NO.2 GROUND CIRCUIT FOR OPEN CIRCUIT • Switch the ignition to off. • Inspect for continuity between throttle body terminal D (wiring harness-side) and PCM terminal 2AP (wiring harness-side). • Is there continuity?	Yes	Go to the next step.
7		No	Repair or replace the wiring harness for a possible an open circuit, then go to the next step.
8	VERIFY TROUBLESHOOTING OF DTC P0223:00 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Start the engine. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF, L5].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF, L5].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [L8, LF, L5].)
9		No	DTC troubleshooting completed.
