VCDS code P0341 (g40) very occasional crank no start issue caused by intermittent camshaft sensor fault ?

mark-nz1 · Jun 30, 2023

Hi guys,

I finally got around to scanning the car and working through the trouble codes. camshaft position sensor comes up, car runs fine but have an occasional crank no start. am I right in assuming the easiest option is just to replace the sensor? any idea on location on the 4.2l? also trying to verify part number is this correct ? 07L905163

also no idea about the intermittent system too rich at idle, any advise appreciated?

thanks !

So the “crank, no start” it most likely caused by:

And the camshaft position sensors:

Camshaft position sensor / rough idle

Hello Had a camshaft position sensor die on my 05 V8. Replaced it after 3 months I still have a rough idle and pending codes. Will this stop? Or should I expect the worst?

Immo is what's causing no start.
The cam sensor is an issue, but will only cause longer crank starts\harder starts.... not no starts.
You can see that is all the FF data, you're showing RPM values..... if the ECU can't see RPMs, then you'll have a no start as well (that is, if you aren't already blocked by immo)

www.clubtouareg.com

Thanks this is a different engine to mine. Mines the newer 4.2 fsi CGNA from a 2012. So the sensor location is different, I have the maintenance manual which just says to pull the air box out on the respective side but no other direction.

Thanks yeah it makes sense, I have ordered a replacement sensor anyway so il fumble around the engine when it arrives and swap it out see if it clears the code .

SaVAGeSoot · Jul 6, 2023

It's not going to clear the IMMO code, but it's your money and time, so go for it.

Yeah of course, Sure but it should prevent the implausible signal from the camshaft position sensor from recurring right ? Cheers

SaVAGeSoot · Jul 6, 2023

Not necessarily.

Intermittent

Have you logged the sensor's readings?
Have you verified connections\wiring?
How did you narrow it down to the sensor being bad? Especially when the code itself clearly says...

16725/P0341/000833 - Camshaft Position Sensor (G40): Implausible Signal

Possible Symptoms

Malfunction Indicator Light (MIL) active

Possible Causes

Wiring from/to Camshaft Position Sensor (G40) faulty
Camshaft Position Sensor (G40) faulty
Timing misaligned
Low level oil or low oil pressure

Looking at the snap shot that it logged when it last detected the code, the only obvious thing that looks out of place is the rpm at 1469 rpm while the engine is sitting at idle.

-Oil is fine
- timing i will figure out how to check ( but other than the occasional no start, there's no other signs of timing issue, misfires, noise, rattles, codes etc)
-could be dodgy wiring but figure if it was the fault frequency would be much higher. But I will check this.
-for 15 bucks I figure changing the part out and check the wiring while I'm in there is worth it.

Anything else I should look at ?

Thanks for your input

Interesting interpretation..... here's mine

Code says it's intermittent and not confirmed - read flaky
It's happened 21 times in the last week - seems sufficiently frequent to suspect a loose wire\connection, or at least warrant looking into that possibility
Idling at 1469 RPM - sure, it's a high idle... but what's your voltage with the car running? Oh that's right.... no where near 14.1-14.3v.... so you probably have an old, weak battery and a weak alternator on top of it..... could it be the ECU has jacked up idling RPM to recharge said battery and perhaps attempt to provide sufficient juice to the rest of the system?

Cool perfect I will check that out thanks

I didnt realise fault frequency was from the past week, I thought it was in the lifetime of the fault code So that's good to know makes sense about the wiring then as you mentioned.

Thanks

It's useless to have the manual if you don't know how to read it.....
Post page 307 so that I can read it for you

It's from the time the fault first happened.... which based on the date stamp is roughly about a week ago.... there's no "lifetime" of the code if you clear the codes.... so without looking at the data of when you last cleared the codes, how many cycles ago, etc. all I have to go by is the date\milage stamp on the FF data.... and I also don't know what your current mileage is, so I'm simply reading the date as I know what today's date is

VCDS code P0341 (g40) very occasional crank no start issue caused by intermittent camshaft sensor fault ?
