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

• Has FREEZE FRAME DATA been recorded?

Yes

Go to the next step.

No

Record the FREEZE FRAME DATA on the repair order, then go to the next step.

2

• Verify related Service Bulletins and/or on-line repair information availability.

• Is any related repair information available?

Yes

Perform repair or diagnosis according to the available repair information.

• If the vehicle is not repaired, go to the next step.

No

Go to the next step.

3

• 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.

No

Go to the next step.

4

• 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.

No

Go to the next step.

5

• Inspect TP sensor No.2.

  (See THROTTLE POSITION (TP) SENSOR INSPECTION [LF].)

• Is there any malfunction?

Yes

Replace the throttle body, then go to Step 8.

(See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [LF].)

No

Go to the next step.

6

• 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.

No

Go to the next step.

7

• 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.

No

Repair or replace the wiring harness for a possible an open circuit, then go to the next step.

8

• 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].)

No

Go to the next step.

9

• Perform the “AFTER REPAIR PROCEDURE”.

  (See AFTER REPAIR PROCEDURE [LF].)

• Are any DTCs present?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [LF].)

No

DTC troubleshooting completed.
