SERVICE INFORMATION

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

CONDITION/CONCERN

A customer may comment that they have an SES with or without a drivability concern, or after performing an engine repair the technician finds the SES is on. Upon investigation a DTC p0017 may be set as current or as history.

RECOMMENDATION/INSTRUCTIONS

Due to the varied amount of concerns that can cause a p0017 code and number of PIs and TSBs for a DTC P0017, this document was created to cumulate all that information for those times when normal published diagnostics does not lead to a repair. Some of these include; the technician may have performed repairs for a secondary or non-related concern such as a cylinder head or front cover replacement and then has a DTC p0017, or still has a DTC P0017 after performing repairs according to published diagnostics. Remember, a DTC p0017 DTC sets when CMP sensor pulse is greater than 16.31 degrees out of sequence with the corresponding crank sensor pulse; as stated in service information.

NOTE: This document is not intended as a short cut to diagnostics listed in SI.

A P0017 code may set for any of the following reasons:

  1. The engine is timed incorrectly. See current version of TSB 06-06-01-017 (RPO's L52, LK5), See current version of 07-06-01-019 (RPO's LLR, LLV) See current version of 07-06-01-018 (RPO LL8) Use these documents to check timing. The technician should follow the procedures to set the engine to #1 TDC then place the straight edge on the cam flats and:
    1. 1.1. If one cam flat has excessive clearance as noted in the TSB that cam is one tooth off.
    2. 1.2. If both are cams flats have excessive clearance as noted in the TSB in the same direction the timing is off at the crank gear.
  2. The crank timing gear has a loose fit to the crank. See current version of PIP4581, The concern could be:
    1. 2.1. The crank key or keyway has excessive clearance
    2. 2.2. The crank bolt is loose.
  3. The Crank end play is excessive. See current version of PIP3694***
  4. The cam actuator solenoid is restricted or screens are missing. See current version of PIP3694
  5. The cam actuator is sticking. See current version of PIP4913
  6. Low oil pressure or oil contamination. See current version of PIP4913

    Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
