Diagnostic Aids
A DTC P1335 can be the result of a defective reluctor wheel. Remove CKP sensor and check the reluctor wheel through sensor hole. Check reluctor wheel for porosity, nicks, dents, etc. and repair as necessary. An intermittent malfunction may be caused by a fault in CKP sensor electrical circuit. Check wiring harness and related components for an intermittent condition. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES - 1.8L VIBE article. Repair any electrical circuit faults found. Information included in freeze frame data can be useful in determining vehicle operating conditions when DTC first set.
