P3425
Cylinder 4 Deactivation/Intake Valve Control Circuit/Open
DTC P3425, sometimes indicated as P342500 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 4 deactivation/intake valve control circuit/open.
The code P3425 is set when the PCM detects a problem with the cylinder 4 deactivation or intake valve control circuit. This could be caused by a number of things, such as a wiring issue, a bad sensor, or a problem with the valve itself.
If you have this code, the first thing you should do is check the wiring and connectors for any signs of damage or corrosion. If everything looks okay, then you should check the sensors and valves for any signs of damage or malfunction. If there is a problem with the valve, then it will need to be replaced.
