DTC P0335:38 [MZ-CD 1.6]

id0102g8353800

DTC P0335:38

Crankshaft position (CKP) sensor circuit signal frequency incorrect
DETECTION CONDITION
•  The PCM monitors the CKP sensor signal. If the PCM detects that the number of teeth per one cycle is deficient or excessive, without losing the synchronism between the number of teeth that the PCM calculates and number of teeth actually detected, the PCM determines that the CKP sensor circuit signal frequency is incorrect.
POSSIBLE CAUSE
•  CKP sensor pulse wheel malfunction
•  CKP sensor malfunction
•  PCM malfunction
