P3412

DTC P3412, sometimes indicated as P341200 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing cylinder 2 deactivation/intake valve control circuit high.

This code is set when the PCM detects a high voltage in the intake valve control circuit for cylinder 2. This could be caused by a short in the wiring or a bad valve. If the code is intermittent, it may be caused by a dirty or corroded connector.
If you have this code, first check the wiring and connectors for any shorts or corrosion. If everything looks good, then you may need to replace the valve.
