DTC P1589 [MZR-CD (RF Turbo)]

id0102f1118000

DTC P1589

Intake shutter valve control range/performance

DETECTION CONDITION

•  The PCM compares the actual intake shutter valve with the target intake shutter valve when the engine is running. If the difference is more than 4.2 ° and less than – 4.2 °, the PCM determines that there is a intake shutter valve control circuit range/performance problem.

Diagnostic support note

•  The MIL illuminates if the PCM detects the above malfunction condition in the first drive cycle.

•  FREEZE FRAME DATA is available.

•  DTCs are stored in the PCM memory.

POSSIBLE CAUSE

•  Intake shutter valve malfunction

•  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 FREEZE FRAME DATA on repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Check for 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.
2		No	Go to the next step.
3	INSPECT FOR OTHER DTCS • Have other DTCs been stored?	Yes	Perform the diagnostic procedure for the applicable DTCs. (See DTC TABLE [MZR-CD (RF Turbo)].)
3	INSPECT FOR OTHER DTCS • Have other DTCs been stored?	No	Go to the next step.
4	INSPECT INTAKE SHUTTER VALVE • Inspect the intake shutter valve. (See INTAKE SHUTTER VALVE INSPECTION [MZR-CD (RF Turbo)].) • Is there any malfunction?	Yes	Replace the intake shutter valve, then go to the next step. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING OF P1589 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. • Turn the engine switch off. • Start the engine and let it idle. • Is the same DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [MZR-CD (RF Turbo)].)
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [MZR-CD (RF Turbo)])
6		No	Troubleshooting completed.
