Question about 2007 Chevrolet Equinox LS New Cars

1 Answer

What do P0016 and P0017 codes mean on a 2010 Equinox?

I have these codes coming up and the service dept couldn't tell me what they meant when I was there...I am taking it in in a few days but I seriously thought they could tell me what they meant. In the meantime I am sticking close to home and not going far.

P0016 is the crankshaft position (CKP) to intake camshaft position correlation; P0017 is the exhaust camshaft position correlation.

P0016 sets when 'The ECM detects 8 of the last 10 cam sensor pulses occur during the incorrect crankshaft position."
P0017 sets when 'The ECM detects 25 out of the last 35 cam revolutions occur with 2 cam sensor pulses outside the CKP window."

Basically, you're getting pulses when they shouldn't happen, from both cam sensors, or the CKP is generating incorrect window info. Since the CKP is the common element, it's probably the culprit.

The cam position sensors are at the back of the head, one on each side corner. The CKP is under the oil filter housing, above the starter. To replace the CKP, you're supposed to remove the intake manifold and starter.

SOURCE: Just bought a 04 Trailblazer

If you bought this at a car dealer, you should take it back for them to fix it (hope you at least got a 30 day warranty). If you bought it privately, it's your problem now.
The P0606 code is relayed to the PCM (Powertrain Control Module), that's the computer. The fault is saying there is an internal memory problem with it. This may or may not be causing all the other fault codes, but it should be the first one to be fixed.
The P0014 & P0016 are related to the camshaft actuator solenoid and crankshaft position sensor.
P0125 is for coolant temperature being too low, P0128 is for coolant temperature not rising fast enough at start up, these could be a bad thermostat.
P0172 is for a rich fuel mixture detected.

SOURCE: fuel pump?

I as well have a 2002 chev blazer 4x4 4.3L, and though I have not exerrienced your paticular problem, I have experienced Service Engine Light on, and generaly I have found it is one of your sensors.
You could have a bad sensor causing your rev problem. What I do is determine if the vehicle still runs as if the service engine light has not come on.
If it runs the same, in my experience it is not as crucial as if you have a performance issue, as you do with reving. If I was you I would try to get to your mech ASAP.
I am not aa mech but, I know our chev blazer very well, and how it should perform.
Hope this helps,

My 2003 Ford Escape is having problems starting - very intermittent - the engine will turn over, but not start when I turn the ignition. This happened initiallly about 6 months ago. I took it in for...

That is a false statement

You can put an Ampere Meter on it, when it is running

You can look at the motor running with an Oscilloscope

You can check Fuel Pressure & Fuel Volume

Your problem has nothing to do with cranking
Cranking is the starter turning over the motor

You have a no start condition, due to lack of fuel pressure

Now you see why I never recommend a dealer
Why would a professional tell you that stuff?

You have a complete fuel pump circuit with other items
that can be checked

You could install a new pump & hope that is the problem,
but if it took 6 months to come back I doubt it

Stiff clutch on 2002 elantra , clutch and transmission new , slave clinder pushes wrong way ,whats wrong ?

FYI, the slave cylinder is pushing correctly, the clutch is the 'PULL TYPE', not the 'PUSH' type.
Go to and register the vehicle by VIN #. You'll then have access to Shop Manuals, Wiring Diagrams, Illustrations, Service Bulletins, etc.

The clutch on the 2002 Elantra, as I mentioned, is the "Pull Type". Instead of 'Pushing' on the throw-out bearing, it "Pulls" on it. The pressure plate engages when the bearing is released (when it is 'pulled' back into the pressure plate 'fingers'

Was the new trans & clutch installed at an authorized Hyundai Service Department? If not, you might want to have them inspect the installation to determine what's wrong. If it WAS installed by a Hyundai Service Dept, take it back to them & tell them to FIX IT!

2002mazdatribute will not run when put in gear and dealership says nothing is wrong??????

Do you know in detail what the dealer actually did?

We get a hundred of these dealer's not caring about
the customer ,every day on this site alone

I won't ever recommend going to one.

That may offend some very good hard working
technicians,but the dealers seem to only be in the
game for the money.
The mechanics have no control over what the
service mgr want them to do

Do you have any check light on the dash?

That could be a bad Transmission Range Switch
if your veh has one.

It probably didn't act up when it was there & you
were one of the few they couldn't find anything else
to take you for,so they return your vehicle

I never go to a dealer after the warrantee runs out
Now you see why.

The check engine light comes on all the time now and the Audi service dept constantly tells me it could be a 1000 reason why it continues to come on and each time I take it to the service dept, it cost me...

There really are 1000 reasons the check engine light is coming on. If you keep resetting it and it comes back on, and it is not affecting the engines performance it is more than likely a faulty sensor. But thats just 1 of the many reasons. They want to keep you coming back so unless you tell them to fix it. They are going to be very vague. Get the obdII software and reader is the best thing I can tell you. Then you can read the code that is tripping the CEL. Hope it helps!
