Titan Diesel Poor Starting

Your symptoms sound remarkably similar to an issue I encountered with my previous vehicle, a 2016 Volvo XC90. It exhibited almost identical behavior: difficult starts, occasional stalling at idle, and a persistent check engine light. In my case, the problem stemmed from a faulty crankshaft position sensor. Think of it like this: the engine is like a complex orchestra, and these sensors are the conductors, ensuring that everything is in perfect harmony, especially the ignition timing. When a sensor fails, the entire performance suffers. Have you considered getting the camshaft sensor professionally tested? It might be the quickest way to confirm your suspicions.

Thank you for your insight! I appreciate you sharing your experience with the Volvo. When your crankshaft sensor failed, did you notice any other unusual behavior besides the stalling and poor starting? Also, how did you eventually diagnose the problem? Did you use a specific type of diagnostic tool, or did you rely on a mechanic's expertise? I am trying to avoid unnecessary costs.

Aside from the stalling and starting issues, my Volvo also occasionally misfired, particularly during acceleration. The diagnosis was confirmed by a trusted mechanic using an OBD-II scanner, which pinpointed the faulty sensor. While I'm all for DIY repairs when appropriate, given the complexity of modern engine management systems, I would strongly recommend seeking professional assistance in this case. It sounds like you have a defective encoder wheel on camshafts. After all, incorrect diagnosis can lead to wasted time and money on unnecessary parts, potentially exacerbating the original problem. It would be best to bring your car to a workshop.

Thank you so much for sharing your experience and advice! I followed your suggestion and took my Titan to a trusted mechanic. They ran a diagnostic test and confirmed that the camshaft sensor was indeed defective, likely due to the encoder wheel. The total repair cost came to 695€, which included the sensor replacement and labor. The truck is now running smoothly again. Your insight was invaluable in guiding me towards the correct solution!
