Fault code information
1 trip MIL
3 drive cycle recovery
Readiness group – None
Freeze frame type – Fuel
Description of component(s)
Effect on the system
* Registration of crankshaft speed
* Registration of crankshaft position
* Synchronization during starting (together with camshaft signal)
* Diagnostic checks on cylinder misfire and cylinder contribution
* Monitoring correct alignment between the crankshaft and the camshaft
* Back up for camshaft signal (F558)
Location of component(s)
Diagnostic condition
This diagnostic runs during starting.
Set condition of fault code
The PCI ECU (D420) detects that the crankshaft sensor (F552) signal does not correspond to the camshaft sensor (F558) signal (engine position) after some engine revolutions.
Reset condition of fault code
This DTC changes to inactive when the fault is no longer detected.

Technical data
Component and wiring checks, crankshaft sensor (F552)
Component check, crankshaft sensor (F552)
Preparation
* Key off the ignition
* Disconnect connector F552
* Measure on component connector F552
Possible causes
* Air gap too large between the camshaft sensor (F558) and the pulse wheel
* Air gap too large between the crankshaft sensor (F552) and the flywheel
* Faulty or soiled camshaft sensor (F558) and/or crankshaft sensor (F552)
* Damaged flywheel and/or pulse wheel
* Incorrect timing gear setting (applicable after a repair)
Additional information
* Camshaft sensor is used as backup to start the engine.
* Engine torque is reduced.
