P0086

DTC P0086, sometimes indicated as P008600 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing exhaust valve control solenoid circuit high (bank 2).

The exhaust valve control solenoid valve is responsible for controlling the exhaust valve on bank 2. If this valve malfunctions, it can cause the engine to misfire and the Check Engine Light to come on.
There are several possible causes of this code, including a faulty exhaust valve control solenoid valve, a bad wiring connection, or a problem with the ECM.
The best way to diagnose the problem is to check the exhaust valve control solenoid valve for resistance and then check the wiring for damage. If the problem is with the ECM, you will need to replace the ECM.
