Ok here are the codes:
P0833
P0013 and P0014 were coming up twice so there you go.
The p0013 and p0014 are codes for the exhaust camshaft positiomn sensor.
Check the wires at the connectors. Pull on each wire at the connector and see if the insulation stretches. Copper wires can break and the insulation looks fine. And follow the wire to make sure theyre not rubbing and shorting out on something. I couldnt find a description of p0833. Did you get a description from the code reader? Gm released a bulletin for the p0014.
Here is the bulletin hope it helps.
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.
