P0286

DTC P0286, sometimes indicated as P028600 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 cylinder 9 injector circuit high.

This code is set when the PCM detects that the injector for cylinder 9 is firing too much.
There are several potential causes for this code, including a faulty injector, a leak in the fuel system, or a problem with the wiring or connector to the injector.
If the code is P0286, it is recommended that you start by checking the injector for proper operation. If the injector is good, then you'll need to start checking the rest of the fuel system for leaks.
