For engines built prior to the following breakpoints: Block Machining debris breakpoint is August 20th for all engines built in Springhill Tn. (Plant code T)
Head Casting sand breakpoint is September 2nd for all Ecotec Plants. ADD APPROXIMATLEY 2 WEEKS FOR VEHICLE MANUFACTURING

This PI was superseded to add the breakpoint for debris, keywords and to define the debris found on the Repair Order. The BLOCK machining chips breakpoint is for engines built in Springhill before August 20th 2009 and the HEAD casting sand breakpoint is for all Ecotecs regardless of build location built before Sept. 2nd 2009. Please discard PIP4469E.

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

In rare instances a technician may comment that they find DTC's for cam phaser operation and/or have noticed a hesitation/stumble (typically on a PDI or with very low mileage). They may have followed eSI diagnostics and the dtc/condition has returned. They may have replaced the ECM with no change and/or they may find one or more of the dtc's listed below.

P0011-Intake Camshaft Position (CMP) System Performance

P0014-Exhaust Camshaft Position (CMP) System Performance

P0016-Crankshaft Position - Intake Camshaft Position Not Plausible

P0017-Crankshaft Position - Exhaust Camshaft Position Not Plausible
Recommendation/Instructions:

Note: Please document on the repair order the type of debris found (i.e. sand or aluminum). When debris is found change the oil and filter before returning to service, in some instances it may be necessary to change the oil and filter multiple times. The filter can be inspected afterwards to ensure no additional debris is present.

Engineering has determined that casting sand and or non-ferrous (aluminum) machining debris in the camshaft phasers/solenoid valves can cause a hesitation/stumble and or these dtc's to set intermittently. This concern typically will occur very early in the vehicle's life or at PDI. When the technician has followed the eSI diagnostic chart for these codes they may be led to ECM replacement; however additional diagnostics should be made before replacement of any parts. When the inspection of the CMP solenoids/actuators and wiring confirms correct electrical operation, check for debris. The recommendations listed below should help.

The technician should inspect each CMP solenoid valve and cam phaser actuator for debris. If debris is found on the solenoid valve screens inspect for torn screens then clean or replace as necessary.

When debris is found on the solenoid valve screens, thoroughly inspect the cam phaser actuators for debris and clean/replace as necessary. If the dtc continues to reset after thorough inspection and cleaning of the cam phaser actuators, replace the affected camshaft actuator(s) depending upon the dtc(s) that set.

Note: When debris is found change the oil and filter before returning to service, in some instances it may be necessary to change the oil/filter multiple times. The filter can be inspected afterwards to ensure no additional debris is present.

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.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
