Cylinder 5 Deactivation/Intake Valve Control Circuit/Open

DTC P3433, sometimes indicated as P343300 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 5 deactivation/intake valve control circuit/open.

The code means that the PCM has detected an open circuit in the intake valve control circuit for cylinder 5. This could be caused by a number of things, including a faulty valve, wiring issue, or PCM problem.
The first step is to check the wiring and connectors for any signs of damage or corrosion. If everything looks okay, then the next step is to test the valve itself. If the valve is found to be faulty, then it will need to be replaced. If the PCM is found to be at fault, then it will need to be replaced or repaired.
