Traveller Camshaft Sensor Failure

Poor starting and stalling on a diesel Traveller could point to several things. Before jumping to conclusions about the camshaft sensor, have you checked the crankshaft sensor? A faulty crankshaft sensor can mimic camshaft sensor symptoms, since the ECU uses both for ignition timing and fuel injection. Have you had any engine misfires or rough running at higher speeds?

Thanks for the quick reply! I haven't checked the crankshaft sensor specifically. I don't think there are any misfires at higher speeds, just the idle issue. Could a defective encoder wheel on the camshafts cause these symptoms as well? Trying to narrow it down before taking it to a shop.

Yes, a defective encoder wheel on the camshafts can definitely cause those symptoms. The ECU relies on the signals from both the camshaft and crankshaft sensors to determine the exact position of the engine components. If the encoder wheel is damaged, it can provide inaccurate signals, leading to the issues you are describing. However, without proper diagnostic equipment, it will be difficult to pinpoint the exact cause. I recommend taking it to a qualified mechanic for proper diagnosis and repair.

Thanks for confirming my suspicions. I took it to the shop, and you were right. The camshaft sensor was indeed defective, likely caused by the encoder wheel. Ended up costing me 695€ to replace. Appreciate the help!
