DTC P0223 [L8, LF]

id0102b1806100

DTC P0223

TP sensor No.2 circuit high input

DETECTION CONDITION

•  If the PCM detects the TP sensor No.2 voltage is to be above 4.9 V after the ignition switch to the ON position, 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.

•  PENDING CODE is available if the PCM detects the above malfunction condition.

•  FREEZE FRAME DATA (Mode 2/Mode 12) 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 2AP

•  TP sensor No.2 malfunction

•  PCM malfunction

DTC P0223	TP sensor No.2 circuit high input
DETECTION CONDITION	• If the PCM detects the TP sensor No.2 voltage is to be above 4.9 V after the ignition switch to the ON position, 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. • PENDING CODE is available if the PCM detects the above malfunction condition. • FREEZE FRAME DATA (Mode 2/Mode 12) 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 2AP • TP sensor No.2 malfunction • PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 12) HAS BEEN RECORDED • Has the FREEZE FRAME DATA (Mode 12) been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 12) 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 AND TERMINALS • Turn the ignition switch off. • Disconnect the throttle body connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector or terminals, then go to Step 9.
3		No	Go to the next step.
4	INSPECT PCM CONNECTOR AND TERMINALS • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the connector 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 • PCM connector is disconnected. • Disconnect the throttle body connector. • Turn the ignition switch to the ON position (engine off). • Measure the voltage between throttle body terminal D (wiring harness-side) and body ground. • 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	VERIFY TP SENSOR NO.2 POWER SUPPLY AND SIGNAL CIRCUIT FOR SHORT TO EACH OTHER • Throttle body and PCM connectors are disconnected. • Turn the ignition switch off. • Inspect for continuity between throttle body terminals E and D (wiring harness-side). • Is there continuity?	Yes	Repair or replace the suspected wiring harness, then go to Step 9.
6		No	Go to the next step.
7	INSPECT TP SENSOR NO.2 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 2AP terminals (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 the throttle body connector. • Inspect the TP sensor No.2. (See THROTTLE POSITION (TP) SENSOR INSPECTION [L8, LF]) • Is there any malfunction?	Yes	Replace the throttle body, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF].)
8		No	Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Turn the ignition switch to the ON position (engine off). • Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [L8, LF].) • Start the engine and warm it up completely. • Perform the KOEO/KOER self test. (See KOEO/KOER SELF TEST [L8, LF].) • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [L8, LF].)
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [L8, LF].) • Are any DTCs present?	Yes	Go to the applicable DTC troubleshooting. (See DTC TABLE [L8, LF].)
10		No	DTC troubleshooting completed.
