DETECTION CONDITION | • PCM monitors input voltage from accelerator position sensor No.1 and accelerator position sensor No.2 while engine is running. If voltage difference exceeds 0.9 V, PCM determines accelerator position sensor No.2 circuit performance problem.
POSSIBLE CAUSE | • Accelerator position sensor malfunction • Connector or terminal malfunction • Accelerator position sensor misadjustment • PCM malfunction

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Check for related Service Information availability. • Is any related repair information available? | Yes | Perform repair or diagnosis according to available Service Information. • If vehicle is not repaired, go to next step.
No | Go to next step.
2 | INSPECT POOR CONNECTION OF ACCELERATOR POSITION SENSOR CONNECTOR • Turn engine switch to OFF. • Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace suspected terminal, go to Step 5.
No | Go to next step.
3 | INSPECT ACCELERATOR POSITION SENSOR • Turn engine switch to OFF. • Inspect accelerator position sensor. (See ACCELERATOR POSITION SENSOR INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Adjust or replace accelerator position sensor, go to Step 5. (See ACCELERATOR POSITION SENSOR ADJUSTMENT [MZR-CD (RF Turbo)].) (See ACCELERATOR PEDAL COMPONENT DISASSEMBLY/ASSEMBLY [MZR-CD (RF Turbo)].)
No | Go to next step.
4 | INSPECT POOR CONNECTION OF PCM CONNECTOR • Turn engine switch to OFF. • Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). • Is there any malfunction? | Yes | Repair or replace suspected terminal, go to next step.
No | Go to next step.
5 | VERIFY TROUBLESHOOTING OF DTC P0221 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear DTC from PCM memory using WDS or equivalent. • Start engine. • Is same DTC present? | Yes | Replace PCM, go to next step. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
No | Go to next step.
6 | VERIFY AFTER REPAIR PROCEDURE • Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Is there any DTC present? | Yes | Go to applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)].)
No | Troubleshooting completed.
