Make sure you got a bad sensor before you replace dont be a part changer,you got to verified if it really cam or connection/wire problem.

Are you saying you have installed a new sensor three times?
Are you buying "counterfeit" sensors?
Looks like a lot of people have similar problems. I googled your problem here is a group that probably has a fix. One said he got sensor from dealer, no more problems! I'd get a genuine Mopar one from a lightly used car in the DIY salvage yards.

WHAT CAN I DO TO REPAIR THIS CODE PO344 REPLACED CAM SENSOR DID NOT HELP CAN YOU PLESES HELP ME


Well code 344 means the signal coming from cam sensor 1 is failing at times. If you have replaced the sensor, it could be the cam, or the wiring.
You may need the actual factory troubleshooting chart for the code to find the problem.

2005 dodge caravan p1684 & p0344


Code 1684 means the computer has lost power since the last check, usually from disconnecting the battery.
Code 344 means the cam sensor on bank one is not always sending a signal to the computer. It could be a wiring problem or something with the actual camshaft.

code p0017 refers to crank/ cam oosition sensor bank 1 sensor B -correlation ===causes --wiring--CKP sensor--CMP sensor--mechanical fault.
It also refers to control modules, cooling fan--no signal===causes -- wiring--ECM.
If it has a timing chain then the the advice that it will not be the chain is good. So I suggest checking out the cam/ crank sensors and wiring

2006 Ford F-250 6.0 Engine just shuts down at an idel or going down the road. it has a bad glow plug and shows a code for it . I just replaced the cam posithion sensor. Does the engine keep shuttting


I have had the same problem with my Ford mustang the only thing is that it only shuts down in high idle, after the engine temperature warms up there is no shut down. It could have something to do with the transmission or the temperature sensor the best thing to do is get a full diagnostic and not do it your self.

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

2003 300M-car stops while travelling-getting a #344 trouble code- what may the problem be?


this is a CAM position sensor fault. More specifically it is an Intermittent cam shaft position sensor code. The likely cause of this is that you will just need to replace the sensor, typically they run from $40-$80 USD and can take up to about an hour to change out. they are located on the front of the motor on the top of the cylinder head. Also they do not require any kind of special tool to change out.

2006 pontiac gxp , check engine light is on codes po431, 430 cam sensor circuit, runs fine clear codes and returns in 2 days !


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.

Idle goes back and forth 700 to 1800 rpm about avery 10 seconds with the a/c on, 700 to 1500 with a/c off. codes show cam positining sensor bank 1 bad, coolant cirtuit high side bad, and back 2 running too...


yep, nothing wrong witht the ac, might need a charge, thats whats causing the high side sensor to go off, as far as the surging you might take off the oxygen sensor and clean it and replace, that usually helps, if not it needs a new one, the oxygen sensor controls the fuel mixture, and crankshaft sensors are kinda cheap so replacing that wont hurt... good luck!

Service engine light


From the GM Factory service Manual:
P0341 - Camshaft Position (CMP) Sensor Performance
The other thing about this code, is that it can be caused by a faulty ignition module, or the cam sensor magnet on the timing chain gear, behind the engine front cover that the sensor mounts to. These possibilities would
require a bit more involved diagnosis than just replacing the sensor related
to the code.
I have done a tech. bulletin search for this code, and come up with nothing.

Again, need to get harness checked, and if wiring OK, further diagnosis of
the ignition system.
