Camshaft Position Sensor Fault Code P034100

[Shortbread69]

Well, It looks like I have narrowed down my "guilty party" for my slow cranks...

New battery, all earth connections cleaned and checked, starter connections checked, fuel filter changed, fuel filter connections checked, all fine...

And tonight this error came on.

Now, the sensor is not expensive, and I know they are known to wear off at the connectors / looms.

Only had time for a quick look for the sensor this afternoon, but where is it in the engine?

Chers for that… will need to have a closer look tomorrow.

Could you please check what OBDeleven reports under:

Control units - Engine - Live Data - Camshaft adaptation intake bank 1: phase position​

Good morning @mmi ...

Readings are:

-0.21 on initial start-up

-0.61 after 5 minutes idling

Thanks... seems to be normal - or ar least similar to mine.

My thoughts too.

Fault wiped, not re-appeared yet.

Still have this issue of one out of 10 cranks being 3 to 5 seconds long.

Working my way through the various options but so many potential origins for this… electric, electronic, fuel, …

i have to say, still can’t hear the initial fuel pump kicking in on crank… but it definitely works when running a fuel pump test…

Recent case where cam position was far enough out for ECU to prevent starting

Problem solved for the smell and non-start. Thanks to everyone who helped with their comments. It was due to camshaft timing.
Smell was timing belt rubber and timing thrown out by water pump pulley failure.
was a new Gates pump 4K ago.
Let’s hope there wasn’t any valve contact.

Certainly could try to monitor "fuel pressure" and/or "Main injection, duration of activation" during long cranking (by OBDeleven live data). Unfortunately OBDeleven is quite slow - but it might work for a single data channel.

About the fault code P0341 00 - it 's actually implausible signal - which most likely indicates that data received from the sensor is out of normal working envelope, thus the actual failure is something that affects camshaft position....

Could you please post freeze frame data of the P0341 fault. Even cleared it still can be found in OBDeleven's "History" - just email the history log to yourself. Also engine section of OBDeleven scan might be useful.

Anyways, had another look on the above. Got a bit curious about such a "big" jump (-0.2...-0.6 degrees) in such a short time. The values themselves are within "spec". I'll do a recording tomorrow to see what mine does.

P034100 - Camshaft Pos.Sensor Circ. Range/Performance Intermittent Priority - 2 Malfunction frequency counter - 3

Had happened 3 times - intermittent thus the fault was not active when scanned.

Malfunction frequency counter - 1 Unlearning counter - 255 km-Mileage - 62624 km Engine speed - 326.50 1/min Normed load value - 100.0 % Vehicle speed - 0 km/h Coolant temperature - 31 °C Intake air temperature - 20 °C Ambient air pressure - 1010 mbar Voltage terminal 30 - 11.160 V

First time obviously during cranking.

I'll do a recording tomorrow to see what mine does.

I did record, however for comparison my engine is EU6 (AdBLue). The value "Camshaft adaptation intake bank 1: phase position" was steady at +1.8 degrees all the way from before start up (engine not running) - cranking - 30 minute drive. However, when sampled over months/years - the value indeed does move around but extremely slowly.

To be exact the value actually did change from 1.7 to 1.8 degrees during the recording. But I take it that as the reported value on mine has (coarse) resolution of 0.1 degrees, it actually just moved from e.g. 1.74 to 1.75 degrees which was then rounded from 1.7 to 1.8 in the log.​

Thank you for your technical assistance...

My average mechanical background is on old engines, where you only have to worry about supplies of electricity. fuel and air.

The electronics adds another layer to this "simpler" equation, of course, plus I have the unpredictability of an intermittent issue.

So, sticking to the basics for now...

New fuel filter has made a big difference to the engine. The old one was not changed in 2020, so was over 2 years old. I have checked all connections / pipe around the filter and beyond, and they appear to be in good condition.

New battery and existing alternator behaving perfectly according to my monitor.

The cranking issue always appear after a period of inactivity (but not necessarily first thing in the morning).

Weather has been steady in Scotland between 15 and 20 degrees, I don't think glow plugs are the problem.

The "inactivity element" naturally points me towards a fuel supply issue (still to be checked as suggested) or a mechanical issue... maybe with the starter motor... To be fair, it is over 4 years old, the van is not fitted with a engine "bottom cover" and the previous owner obviously enjoyed driving in sand/dust... the whole engine was caked with it. May simply require a new starter motor - I believe they can throw a Cambelt Sensor error when they are on the way out?

Anyway, will keep plugging away

As ever, suggestions welcome!

Thread revival! Mine was -5 and i have just bumped mine as close to zero as i can get at +0.22. Adjustments can be made on the cam but beware they are absolutely minute and its easy to get it out of parameters so it wont start. Make sure you mark your starting point with a paint pen. It's trial and error but very doable. More or less the same as setting torsion value on the PD engines. The van seems much smoother and it seems to pull a bit better further up the rev range now.

Hi,
What was your problem when trying to start?
After a short journey, the next start up is an extended crank start or hard start it's called I think. I'm being told its possibly a crank sensor. How did you get on with your sensor and did it sort out your problem?
