P0085 Fault Code

P0085 OBD-II Trouble Code Short Description

Exhaust Valve Control Solenoid Circuit Low (Bank 2)

What does trouble code P0085 mean?

The P0085 fault code indicates an issue with the Exhaust Valve Control Solenoid Circuit Low on Bank 2 of the vehicle's engine. This means that there is a problem with the electrical circuit that controls the exhaust valve solenoid on the specified bank.

The exhaust valve control solenoid is responsible for regulating the flow of exhaust gases, which is crucial for the proper functioning of the engine and emission control system. When the circuit is detected to be operating at a lower voltage than expected, it triggers the P0085 fault code.

The potential causes of this issue could include a faulty exhaust valve control solenoid, damaged wiring or connectors, or a problem with the engine control module. To resolve this problem, it is recommended to start by inspecting the wiring and connectors for any signs of damage or corrosion. If no issues are found, the next steps may involve testing the solenoid and the engine control module for proper functionality. If any components are found to be faulty, they should be repaired or replaced to clear the fault code.

Ignoring or neglecting this issue could result in reduced engine performance, increased emissions, and potential damage to other engine components over time. It is important to address the P0085 fault code promptly to ensure the continued proper operation of the vehicle.


What are the symptoms of the P0085 code?

  • Poor engine performance
  • Rough idling
  • Decreased fuel efficiency
  • Engine misfires
  • Illumination of the Check Engine Light


What causes the P0085 code?
