Replaced CPAS and changed oil...now I have a p0014 code and p0340. Could I just have bad luck and need to replace the camshaft sensor now too?

More than likely the wiring was broke when replacing the cpas. Has happened before. Its just too much of a coincidence that the sensor itself would fail at the same time.

Had them rechecked at a different advance auto...I have a few codes... I have 0014, 0014 again but this one said pending, and 1 that read 0340. Pending just means it's not cleared out of the system yet right?

Also just found out I have no cruise control. Not that I use it very often anyway, but still.

I have heard of aftermarket CPAS sensors being bad right out of the box but double check the wiring. I
would recommend AC Delco. As for "pending" that term is given to previously set codes.
Criuse control could be any number of things as there is so much redundancy in that
system. Could be as simple as a brake light switch acting up.

GM disables the cruise control if something vital to the operation of the vehicle goes wrong. It's basically to get ma and pa's attention so they take it into the shop. Soviet style tactics if you ask me.

Died this morning on startup...2nd try started right up. Leaving work now and can't get the truck to start. Cranks...then dies immediately...check gauges light was on this morning.

Never seem to catch a break.

Well neither the CPAS or the camshaft sensor are required to start the engine. Try to unplug it and see if it runs. Or...something else is wrong.

I did buy an aftermarket part...maybe i'll go out today and pick up an AC delco one to see if that helps.

It starts, but just dies immediately...I had a similar experience a while ago where it would turn on then immediately die (Low oil pressure according to the DIC)...but nothing like that was displayed on the DIC this time.

Possibly the Crankshaft sensor or VATS is possibly screwing up.

Crankshaft sensor is on the drivers side of the engine?
I just went out and bought a new CPAS from the dealer. I'll replace that sometime tomorrow if I get time.

The truck not started couldn't have happened at a worse time. I'm having issues with my wifes jeep stalling, work has been hectic, and i'm dog watching my sisters two dogs, etc. etc.

I probably would worry about it. I think you would have a bunch of other codes to go along if the crank sensor was bad. But here is the location in case your interested.

thanks for the diagram.. I'll start putting in the dealer cpas and I'll buy a new camshaft sensor too. Just need to wait for my wife to get home from work so she can drop me off at the parking where my truck is sitting.

then if I still have issues I'll try the crankshaft sensor.. Looks fun to try and get to.:no:

If you do replace the crankshaft sensor then you will need to have a CASE relearn done from a shop that can. I think dealers charge $80 for it? Could be wrong. It wont keep it from running if you don't get the CASE relearn done right away but eventually it needs to be done.

I would check the wiring around that area and reseat it first.

problem solved. It was a faulty(my fault for buying non oem)cpas. Replaced it with the dealer one this morning. Started right up. Would a bad cpas give off a code for the bad camshaft sensor? I'm going to run to advance auto later today to get the codes read again. They are probably sick of seeing me by now.

Ok...so I drove it all day with no issues. Ran out to Lowe's with my wife...now it's saying oil pressure low and the engine dies. Oil pressure switch was changed about 2 months ago.

Can a bad camshaft sensor cause stalling?

Not that I am aware of. I removed mine more than a couple times and it never stalled. But many things can cause stalling. For instance:

1. Damaged ignition system components including ignition switch
2. Bad fuel pump relay or wiring
3. Bad alternator
4. Bad gas
5. Torque converter locking up

A P0340 indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

I'm getting low on gas now...it's not like I just filled up a couple days ago. Been using the same gas since the 13th. The other parts alt.,ignition switch fuel pump are all still original 110K miles 9 years old. I'll try the cps since it's the easiest and cheapest. If I can at least get it home today i'll be happy...maybe I can take a side trip to advance auto and get them to check my alternator.

update time. Put in a new camshaft sensor. started right up. Just drove it home. No sputtering....no stalling. I noticed the old sensor was damaged. I could easily pull the computer chip out of the sensor. I must have bumped it while working on the truck and it cracked it open...i'll take pictures of it later today. I have to go back to work now. Took me all of 15 minutes to change too.

Anyone know if you replace the camshaft sensor or crankshaft sensor you have to do relearn? I seen someone posted camshaft you have to but unsure if you need to for crankshaft. Also its okay to change out and drive to shop to have them do the relearn? Thanks in advanced

You do need a case relearn with the crankshaft sensor, not with a camshaft sensor.

^^^ Agreed^^^ and you can drive to get the case relearn done with no problems.

Stick with Ac Delco parts... after all, if you buy them through Amazon or eBay, you end up paying at the most a few dollars more than what your local aftermarket auto parts store sells the part for...peace of mind that the part will work is priceless... :smile:

What's it to you that I'm updating my own threads? A lot of people never end up updating their own threads, leaving people to wonder what happened...

This one, specifically wasn't your thread. The culture here is like many forums: unless there's significantly new information to add to a thread, necroposting (as it's called) is mildly discouraged. But if you're reading the forum through Tapatalk (I don't know if you are or not), people's profiles don't automatically show up as senior members or even staff. Larry here (djthumper) is a friend and long time enthusiast and we made him a mod on the sister site I co-own, offroadtb.com. Just to lay down some background. Carry on. :yes:
