P0085

2017-10-10

Description:

  • The fault code P0085 indicates a low voltage condition in the exhaust valve control solenoid circuit for bank 2. It suggests a problem with the solenoid or its associated wiring, resulting in inadequate control of the exhaust valves.

Possible Symptoms:

  • Illumination of the Malfunction Indicator Lamp (MIL) or Check Engine Light (CEL)

  • Decreased engine performance or power

  • Rough idling or stalling

  • Poor fuel efficiency

  • Possible misfires or hesitation during acceleration

Possible Causes:

  • Faulty or malfunctioning exhaust valve control solenoid

  • Wiring or connector issues in the solenoid circuit

  • Open circuit or excessive resistance in the solenoid circuit

  • Potential ECM (Engine Control Module) failure

Related Parts:

  • Exhaust Valve: The exhaust gases after combustion are sent out of the engine through the exhaust valve. Problems lead to harmful emissions out of limit

Possible Solutions:

  • Inspect the exhaust valve control solenoid and its wiring for any visible damage or loose connections

  • Verify the voltage and continuity in the solenoid circuit using a multimeter

  • Check the solenoid and its connector for signs of corrosion or moisture

  • Replace the exhaust valve control solenoid if it is determined to be faulty

  • If necessary, diagnose the ECM for potential malfunctions and replace if needed
