DTC P0222 [L8, LF]


DTC P0222	TP sensor No.2 circuit low input
DETECTION CONDITION	• If PCM detects TP sensor No.2 voltage is to be below 0.1 V after the ignition switch to the ON position, the PCM determines that 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 is available. • The DTC is stored in the PCM memory.
POSSIBLE CAUSE	• TP sensor No.2 malfunction • Connector or terminal malfunction • Open circuit in wiring harness between throttle body terminal E and PCM terminal 2AO • Short to ground in wiring harness between throttle body terminal E and PCM terminal 2AO • Open circuit in wiring harness between throttle body terminal D and PCM terminal 2AL • Short to ground in wiring harness between throttle body terminal D and PCM terminal 2AL • PCM malfunction


STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Have FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the 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 THROTTLE BODY 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). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
3		No	Go to the next step.
4	INSPECT TP SENSOR NO.2 CIRCUIT FOR SHORT TO GROUND • Turn the ignition switch off. • Inspect for continuity between the following circuits: - Throttle body terminal D (wiring harness-side) and body ground - Throttle body terminal E (wiring harness-side) and body ground • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to ground, 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].) • Is there any malfunction?	Yes	Replace the throttle body, then go to Step 8. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L8, LF].)
5		No	Go to the next step.
6	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). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 8.
6		No	Go to the next step.
7	INSPECT TP SENSOR NO.2 CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch off. • Inspect for continuity between the following terminals: - Throttle body terminal E (wiring harness-side) and PCM terminal 2AO (wiring harness-side) - Throttle body terminal D (wiring harness-side) and PCM terminal 2AL (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 P0222 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].)
8		No	Go to the next step.
9	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 inspection. (See DTC TABLE [L8, LF].)
9		No	DTC troubleshooting completed.
