DTC P0222[MTX, LF ATX (FS5A-EL)]

id0102b4806000

DTC P0222

TP sensor No.2 circuit low input

DETECTION CONDITION

•  The PCM monitors the input voltage from TP sensor No.2 when the engine is running. If the input voltage is below 0.2 V, the PCM determines that the TP sensor No.2 circuit input voltage is low.

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 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 B and PCM terminal 2AO

•  Short to ground in wiring harness between throttle body terminal B and PCM terminal 2AO

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

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

•  PCM malfunction

DTC P0222	TP sensor No.2 circuit low input
DETECTION CONDITION	• The PCM monitors the input voltage from TP sensor No.2 when the engine is running. If the input voltage is below 0.2 V, the PCM determines that the TP sensor No.2 circuit input voltage is low. 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 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 B and PCM terminal 2AO • Short to ground in wiring harness between throttle body terminal B and PCM terminal 2AO • Open circuit in wiring harness between throttle body terminal C and PCM terminal 2AL • Short to ground in wiring harness between throttle body terminal C and PCM terminal 2AL • PCM malfunction

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 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 B and body ground ― Throttle body terminal C 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[LF, L3].) • Is there any malfunction?	Yes	Replace the throttle body, then go to Step 8. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION[LF, L3].)
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 B and PCM terminal 2AO ― Throttle body terminal C and PCM terminal 2AL • 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 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[LF, L3].)
8		No	Go to the next step.
9	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE[MTX, LF ATX (FS5A-EL)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[MTX, LF ATX (FS5A-EL)].)
9		No	DTC troubleshooting completed.
