|Since this solenoid only controls oil to the exhaust cam phaser why would the crank
sensor variation re-learn procedure need to be done if it is replaced? Nothing with the
cam to crank timing is effected by replacing that control solenoid.
|After I have changed the exhaust cam actuator solenoid,how do I do a relearn?
|You need a scan tool that has that capability of doing the
relearn. You can go to the dealer and pay 1/2 labor to
have them do it for you.
|Hello to all,
Ok i have a 2002 Chevy Trailblazer, first go to your local auto store and have them do
a free diagnostic. I use AutoZone. Once it comes up P0014..then you just saved over
$100+. Now call a major Chevy dealer and buy the cam actuator for about $100.00.
Make sure you do not by a refurbished,or a used one. It is about 6 inches long w/ holes
in the groves,that part goes in the motor and a solid end 1" with a connector on
the end that is visible.(silver) It is located by the power steering pump. Then have your
trusted mechanic do the job..it totals about $150.00+ for everything ,if you have the
dealer do it,its about $700.00. When you replace this, I recommend a tune-up, plugs
and oil change at the same time, and to replace the camshaft positioning sensor(its
above the cam actuator) it costs about $30 at an auto store.......Then once the auto
shop replaces this they will rest the cars computer...then take a long drive on the
highway 25min there and 25min back ...
Then park the car let it completely cool down . Then start the car up and let it run on
idle for about 5-10min with everything on....then take a ride to the auto store i use Auto
Zone. To have another diagnostics check, even if the light Isn't on, This way you know
everything is working properly and its free...This i would not recommended doing your
self..even if you have basic mechanical skills ,this small part controls just about
everything....I hope this helps , good luck....-JB
|I am a heavy engine mechanic at a GM Dealership. The CASE relearn procedure is
NOT NOT necessary when the camshaft actuator solenoid is replaced.
A CASE relearn is ONLY required when the crank sensor has been replaced. Dont
waste your money unless you have replaced your crank (CKP) sensor.
|Replace the CPAS yourself. It's simple. Remove the serpentine belt, remove the three
bolts holding the power steering res and move it out of the way, unbolt the unit and
I can do it in about 20 minutes...
|Even after replacing actuator the p0014 still pops back up after a few miles. No change
in engine performance.
|With an actual actuator replacement, you may need to do a crank variance relearn. Or
you have another problem, like a worn timing chain.
|If the cam actuator goes bad will it make the engine sound like its knocking? There are
three screens on it and one of mine in the middle was clogged up with junk and a little
bit of metal shavings.
|No, it will not cause an engine noise. The metal in the
screen is caused by a worn out engine bearing, and the
metal just happens to be caught in that screen.
