P033FCrankshaft/Camshaft Loss Of Synchronization
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- To know which stroke each cylinder is in, the engine module matches the crank angle with the camshaft phase. P033F means this synchronisation is lost while running or cannot be established. It is documented by code only at Ford (2020–2023): P033F, as an alternative to Ford's older own code, stands for a disturbed crank signal without crank/cam synchronisation, and then misfire detection is also impossible. Ford's 2012 description shows the reaction: on a crank sensor fault the module cuts fuel and spark and resynchronises – one revolution to find the gap, one more to confirm cylinder 1 via the camshaft sensor. FCA evaluates the same function in its own cam/crank synchronisation monitor under other codes. Besides the sensors, a jumped timing chain or belt can be behind it.
- What you may notice
- Jerking, brief loss of power
- Engine stalls, hard starting
- Misfire detection inactive
- Check engine light on
- Likely causes
- LikelyNoisy or disturbed crankshaft signal (sensor, air gap, interference)
- PossibleDisturbed camshaft signal
- PossibleTiming chain or belt jumped or heavily stretched
- PossibleWiring or connector
- RareTone wheel damaged or loose
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
