For addressing the P0014 Code... Start here:
If your
CPAS (Camshaft Position Actuator Solenoid) shown in these Videos has Oil around and inside of the Electrical Connector… and/or if the Internal Screens are Clogged with Dirt and Sludge…
or are missing entirely... it will have to be replaced. In the first two Videos… MAC-T uses the incorrect name for the CPAS as being a
“VVT” ... but he is actually referring to the
CPAS. These Videos will instruct you in how to R&R the CPAS… and if necessary…. also replace the
CPS (Camshaft Position Solenoid) in the third Video if needed. Avoid using the Dorman CPAS and follow the recommendations other Members will mention for the only acceptable replacement part. Be sure to Clear the Codes after these repairs.

The PERFECT HOW-TO Thread available here on GMT Nation for
the easiest way to perform this job as well:
For the 4.2L Set-up:
For the 5.3L Set-up:
Please understand that with such a High Mileage SUV... If your Oil is particularly dirty or has had extended periods between Oil Changes... without performing an Engine Flush using A Cheap Oil Filter, (6) Quarts of Cheap Organic Motor Oil.. and (1) Quart of either Transmission Fluid or Engine Flush to run inside the engine for ONLY (5) Minutes at IDLE...without racing the engine or elevating the RPM... then the Clogged Screens inside of the New CPAS will likely re-occur. The Proper and Sensitive Functioning of the CPAS is absolutely dependent upon Clean, Proper Viscosity Motor Oil.... So after performing this task... Immediately Change the Oil to (7) Quarts of Mobil1 5W-30 (or 0W-30 in Very Cold Climes) and use a High Grade Oil Filter such as K&N or Mobil1 Brands...and note the Mileage so that you can Change Your Oil Every 3,000 Miles!
