DTC
P0336 (Tooth Number Error) Refer to DTC P0336: Crankshaft Posit ion (CKP) Sensor Performance. P0336
MONITOR STRATEGY DESCRIPTION
Tooth Number Error:
The number of teeth per crankshaft revolution is monitored by the crankshaft signal acquisition. The algorithm may tolerate a number of missing/additional teeth per revolution without loosing synchronization, depending on the used target wheel and on configuration data. A flag indicates wrong tooth number during the most recent crankshaft revolution.
If a tooth was missing or added during one revolution, then all variables based on teeth counting will be produced with an error. This concerns for example spark advance, segment time, misfire segments, camshaft position, etc. The purpose of the function is to provide information when the crankshaft signal is inaccurate, in order to take the necessary actions.
MALFUNCTION CRITERIA AND THRESHOLD VALUE(S)
Number of teeth differs by more than 2.

DTC
P0337 Refer to DTC P0337: Crankshaft Position (CKP) Sensor Malfunction. P0337
MONITOR STRATEGY DESCRIPTION
The purpose of the function is to detect a failure if synchronization on crankshaft signal cannot be achieved.
One of the available camshaft signals is selected for crankshaft synchronization by setting one flag in the engine position control function. The signal edge counter of that camshaft is observed while the crankshaft is not synchronized. If the count reaches a calibrated number, and the system is still not synchronized with the crankshaft signal, then crankshaft sensor plausibility error is set without further debouncing. If valid crankshaft teeth have already been detected, the symptom will be "implausible signal", otherwise it will be "missing signal".
