    Epc light on again . Vw touran 2.0 fsi 04. Can any help please

    Hi all. I have a on going issue with the epc light coming on.

    Camshaft position sensor code P0341. I have replaced sensor twice. And after a day or two the same message appears. Have just replaced cambelt and water pump as it was due anyway. Now the same epc light and same error code comes on straight away. And ideas would be very much appreciated.

    You missed the P of that error code I've corrected your post. What was it scanned with a generic scanner or VAG-COM\VCDS?

    VAG Error Code: 16725/000833/6039/4113
    EOBD II Error Code: P0341

    Fault Location:
    Camshaft Position (Hall) Sensor (G40) - Implausible Signal

    Possible Cause:
    Malfunction Indicator Lamp (MIL)(K83) active.

    Wiring/Connector(s).
    Camshaft Position (Hall) Sensor (G40) faulty.
    Timing misaligned.

    Possible Solutions:
    Check/Replace all faulty Wiring/Connector(s)..
    Read Measuring Value Blocks (MVB).
    Check Camshaft Position (Hall) Sensor (G40).
    Check Timing.

    Tech Notes:
    Sometimes and in some models, low battery voltage or a weak starter can trigger a Camshaft Position Sensor code.

    When is the code detected?:
    The camshaft position sensor signal sent to the Engine Control Module (ECM) during the first few seconds of engine cranking is out of range.

    Description:
    The Camshaft Position (Hall) Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module (ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The Camshaft Position (Hall) Sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change. When the Crankshaft Position Sensor system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

    Its strange that some Touran 1.6 FSI, 1 engine code are timing belt but that isn't FSI and some are chain.

    Hi Keith, thank you for the reply. The code has been read by a generic scanner, but also a snap-on one which i assume is a vag com vcds ( sorry for my lack of knowledge on this). It has given the same error code with no other faults etc. Going to check timing etc, also before the cambelt and water pump was changed the epc light didnt come on straight away, maybe a 1 2 or 3 days after clearing error code down. Just need to find timing diagram to be sure. My mechanic did mark it up before replacement but maybe that was wrong?

    The AXW engined Touran is an extremely rare beast (2003>2004 only) and is a car that is soon to be fought over and sought after by those needing an EU4 petrol engined MPV at sensible money with a decent sized engine when living in or regularly using Toxicity zones, one of my customers was hit with a near 300 bill recently after going into London and staying a few days not knowing anything about the T Zone. Unfortunately this engine suffers terrible problems with the cam to cam relay chain inside the box on the end of the head with the fuel pump on. Unfortunately the repair kit is 750 but if you don’t do it you will destroy the engine, I have seen three cases recently. Also the same code can randomly be generated by a block oil pump pick up but if it is a “hard code” as we call it, stop running the engine or you will be pulling the head off as well!

    Vile Invention

    Dark was that day when Diesel conceived his grim engine that begot you, vile invention, more vicious, more criminal than the camera even, metallic monstrosity, bale and bane of our culture, chief woe of our Commonweal. How dare the Law prohibit hashish and heroin yet license your use, who inflate all weak inferior egos? Their addicts only do harm to their own lives: you poison the lungs of the innocent, your din dithers the peaceful, and on choked roads hundreds must daily die by chance-medley. Nimble technicians, surely you should hang your heads in shame. Your wit works mighty wonders, has landed men on the Moon, replaced brains by computers, and can smithy a "smart" bomb. It is a crying scandal that you cannot take the time or be bothered to build us, what sanity knows we need, an odorless and noiseless staid little electric brougham.

    Hi. Thank you for the reply, i do have a question. Would there be running problems if it were the cam cam relay chain and needing the 750 kit etc. Also since cam belt change the epc comes straight on after the next engine restart, where as before it would take some time. What do you think i should do next. Vw garage ?
    Also many thanks again

    Well spotted Crasher but that is 2.0 not 1.6 Steve1233 has changed his car spec to 2.0.

    Manufacturer: VW, Date(s) Used: 10/2003-05/2004, Model: Touran, Engine Code: AXW, 110Kw, 150PS, 2.0 Ltr, 4 Cyls, Remarks: Fuel Stratified Injection (FSI) Timing belt

    That's the problem when member don't have the right car spec and expect answers.

    Well someone has changed it, I don't recall it was me. That's why I posted 1.6 FSI engine codes.

    Hmm. Using my mobile but it will not allow me to change profile etc. Could you please change it to 2.0 FSI. Also thanks again, this is a really good forum.
