Need cam sensor information. service engine light is on.

as to the traction/stability trac check hub and abs sensors [wires and connection ] these systems are not tied into the cam sensor but ---look for wire chaffing in the harness by the cam sensor the harness may have the wiring from both systems in harness

Hi Tjbutina1, Im AL the owner of Big As Auto Repair.

The code P0016 is a crank and cam misalignment code.

Depending on the engine you have can mean different things, so please when you need help the more information you give us will help us help you.

If you have a 1.8 or 2.0 or 2.4 Liter Engine there is a Chrysler Service Bulletin for reprogramming the engine controller among other things that need to be done for this code. It will need to be done at a Chrysler Dealership. TSB: 18-018-07

If you have a 2.7 or 3.5 Engine. You'll need to check the Cam and Crank Sensor Tone Wheels for being loose or cake with debris. You'll also need to check the wiring from the cam and crank sensor to the engine controller for any kind of damage and you'll need to check the timing to make sure it has note jumped a tooth causing it to be at of alignment. Hope this helps and please visit my auto-repair-website here: http://www.bigasautorepair.com/

That one is old enough that you should be able to disconnect the battery for a couple of minutes to reset the computer. I would not be surprised if the light came back on shortly after doing this. The cam sensors rarely fail. It is more likely that the magnetic "cam button" has fallen off the camshaft pulley. The button is what the cam sensor is looking for. If the button is missing than the cam sensor has nothing to read and the check engine light comes on. To check and see if the cam button is missing you can pull the cam sensor. Use a mirror to look through the hole. Rotate the crankshaft by hand with the key off for two complete revolutions. You should see the cam button move through the opening at some point. Good luck!

replace crank senser, first, always replace together, also chk some time double cam motores have to cam sensers.

if its throwing a code for cam sensor but new sensor does not fix it given the fact of recently replacing the timing chain id say it sounds like the timing was not set correctly which is causing the cam sensor to receive abnormal readings throwing the check engine light on. pull cover and check timing mark placement against specifications

Congratulations! You have discovered that clearing codes without diagnosing and repairing the problem that caused the code only results in a repeat repair! You now know more than half of the "mechanics" out there.

OK, on a more serious note: First we have to get the codes straight or get the car straight...I'm pretty sure it is the code that is not correct....Code P0431 and/or P0430 are not valid codes for a 2006 Pontiac Gran Prix GXP. Those are evaporative emissions system codes that do not apply to your car. However, since you mentioned "cam sensor circuit", I will assume at this point that you meant to say P0341 and P0340....BIG DIFFERENCE!

The next problem is that although they are very similar, the troubleshooting charts are different depending on whether your GXP is equipped with a 3.8L engine or a 5.7L engine. If you want help with a problem like this it is REALLY IMPORTANT that we know what we are working on. Otherwise, you may get some VERY GOOD information that does not apply to your vehicle and the "expert" will probably be thought of as "incompetent" for giving you bogus advise. Then comes the bad ratings, and no testimonials, etc. and it wasn't the expert's fault he didn't have the correct information to work with!
It's just not FAIR!!!

ANYWAY.......

For either engine, Diagnostic Trouble Code (DTC) P0341 is not necessarily a "Circuit" problem. Although it may be) This code is usually caused by mechanical failures - See the list below.

CONDITIONS FOR SETTING THE CODE
1. The PCM detects the following every 2 engine revolutions:
. A. 36 medium resolution engine speed signals
. B. 6 low resolution engine speed signals
. C. More than 1 cam sensor signal (herein lies the problem - there should be only one)
2. The conditions in item #1 above are met for at least 4 consecutive seconds.

When the conditions above are met, the PCM sets a "Pending" code for the current drive cycle. On the second consecutive drive cycle that that the same conditions occur, the PCM will store a memory code and turn the Service Engine Soon or Check Engine light on. This explains why it takes a couple days for the light to come back on...It takes a minimum of 2 drive cycles to turn the light on. If it fails on this drive cycle, and not the next, the counter starts over. It could conceivably take weeks or even months for the thing to fail two times in a row if it is an intermittent problem.

If it is failing on a regular basis, the conditions (or causing symptoms) can be verified by using a lab scope and tracing the cam sensor signal and the medium or low resolution engine speed signal. Just count the pulses - if there is more than one cam sensor pulse for every 6 low resolution pulses or 36 medium resolution pulses, the problem has been verified. Now, to find the actual CAUSE so we can fix it.

The most common cause of this is miss-routed or bad ignition (spark plug) cables that are "spiking" the cam sensor circuit.

This code can also be caused by:
Camshaft reluctor ring damage
The cam sensor coming into contact with the reluctor ring
foreign material passing between the reluctor ring and the cam sensor.
Wear or damage to the timing chain, timing chan sprockets, or timing chain tensioner
Excessive camshaft end play

Now DTC P0340 is really the opposite problem.
If your car is setting both of these codes at the same time, you have a really erratic cam sensor signal that should be VERY easy to verify with a scope.

DTC P0340 sets under the same conditions except instead of having more than 1 cam sensor pulse, there are NONE.

This code is usually caused by the cam sensor itself, however it can also be caused by the circuits to the cam sensor. The integrity of the circuits should be verified before replacing te cam sensor for this code.

If your check engine light is blinking, you can take your car to Autozone, Advanced Auto or other parts house and ask them to get the engine codes. This ios a FREE service. It sounds like your camshaft positioning sensor, Cam Positioning sensor is bad. This is how comuterized systems tell where the cam and crackshaft are to set the timing. It sounds like you have timing issues.

replace it before you end up spending more than you want to $$$$,regee

Check you Mas Air Flow sensor or MAP sensor.
