DTC P0092 [MZR-CD (RF Turbo)]

BME010200001W08

DTC P0092 | Suction control valve circuit high input
--- | ---
DETECTION CONDITION | • PCM monitors input voltage from suction control valve while engine is running. If input voltage from suction control valve does not change from on to off, PCM determines suction control valve circuit high input.
POSSIBLE CAUSE | • Suction control valve malfunction • Connector or terminal malfunction • Short to power circuit in wiring between suction control valve terminal A and PCM terminal 93 • Short to power circuit in wiring between suction control valve terminal B and PCM terminal 94
• 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 SUCTION CONTROL VALVE 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 6.
No | Go to next step.
3 | INSPECT SUCTION CONTROL VALVE CIRCUIT FOR SHORT TO POWER • Turn engine switch to ON (Engine OFF). • Inspected voltage between following harnesses:

  - Suction control valve terminal A and body GND.
  - Suction control valve terminal B and body GND.

• Is voltage below 1.0 V?
Yes
Go to next step.
No | Repair or replace harness for short to power, go to Step 6.
4 | INSPECT SUCTION CONTROL VALVE • Inspect suction control valve. (See SUCTION CONTROL VALVE INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction? | Yes | Repair supply pump, go to Step 6. (See SUPPLY PUMP INSPECTION [MZR-CD (RF Turbo)].)
No | Go to next step.
5 | 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 Step 6.
No | Go to next step.
6 | VERIFY TROUBLESHOOTING OF DTC P0092 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.
7 | 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.
