DTC P0222 [MZR-CD (RF Turbo)]

BME010200102267

DTC P0222 | Accelerator pedal position (APP) sensor No.2 circuit low input
--- | ---
DETECTION CONDITION | • The PCM monitors the input signal from accelerator pedal position sensor No.2. If the voltage from accelerator pedal position sensor No.2 is less than 0.3 V, the PCM determines that there is a malfunction in the accelerator pedal position sensor No.2 circuit. Diagnostic support note
• 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 | • APP sensor No.2 malfunction • Connector or terminal malfunction • Open circuit in wiring harness between APP sensor terminal A and PCM terminal 90 • Short to GND in wiring harness between APP sensor terminal A and PCM terminal 90 • Open circuit in wiring harness between APP sensor terminal C and PCM terminal 88
• Short to GND in wiring harness between APP sensor terminal C and PCM terminal 88
• 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.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related service 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 | VERIFY CURRENT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? • Connect the WDS or equivalent to the DLC-2. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Go to the next step.
No | Intermittent concern exists. Perform the "INTERMITTENT CONCERN TROUBLESHOOTING". (See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD (RF Turbo)].)
4 | INSPECT APP SENSOR CONNECTOR FOR POOR CONNECTION • Turn the engine switch off. • Disconnect the APP sensor 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 9.
No | Go to the next step.
5 | INSPECT APP SENSOR NO.2 CIRCUIT FOR SHORT TO GND • Turn the engine switch off. • Inspect for continuity between the following terminals and body GND:

  - APP sensor terminal A (wiring harness-side) and body GND
  - APP sensor terminal C (wiring harness-side) and body GND

• Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to GND, then go to Step 9.
No | Go to the next step.
6 | INSPECT APP SENSOR NO.2 • Inspect the APP sensor No.2. (See ACCELERATOR PEDAL POSITION (APP) SENSOR INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Replace the APP sensor, then go to Step 9.
No | Go to the next step.
7 | INSPECT PCM CONNECTOR FOR POOR CONNECTION • Turn the engine 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 9.
No | Go to the next step.
8 | INSPECT APP SENSOR NO.2 CIRCUIT FOR OPEN CIRCUIT • Turn the engine switch off. • Inspect for continuity between the following terminals:

  - APP sensor terminal A (wiring harness-side) and PCM terminal 90 (wiring harness-side)
  - APP sensor terminal C (wiring harness-side) and PCM terminal 88 (wiring harness-side)

• Is there continuity?
Yes
Go to the next step.
No | Repair or replace the wiring harness for a possible open circuit, then go to the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0222 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the WDS or equivalent. • Start the engine. • Is the same DTC present? | Yes | Replace the PCM, then go to the next step.
No | Go to the next step.
10 | VERIFY AFTER REPAIR PROCEDURE • Perform the Repair Verification Drive Mode. (See OBD DRIVE MODE [MZR-CD (RF Turbo)].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | DTC troubleshooting completed.
