Spark Camshaft Sensor Issue

I had something similar happen with my Spark. The check engine light was driving me crazy! Did you notice any issues with the ignition timing? I remember reading something about how a defective encoder wheel on the camshafts can mess things up and trigger the sensor. It sounds like we have the same problem. I wonder, have you tried any sensor testing to confirm?

Interesting! I haven't specifically checked the ignition timing, but I'll look into it. What kind of sensor testing did you do, and what were the results? I'm curious to know if it's something I can diagnose myself before taking it to a shop.

Honestly, I'm not super technical, so I didn't do the testing myself. Given the symptoms and what I had read online, I suspected a sensor failure and took it straight to a trusted workshop. They confirmed it was indeed the camshaft sensor and that the encoder wheel was faulty. In the end, with parts and labor, it set me back about 700€. I would advise you to take your car to a professional.

Thanks for the insight! Sounds like I'm dealing with the same encoder wheel issue. I'll take it to my local mechanic and get it checked out. I appreciate you sharing your experience; it helped me narrow down the problem. I'll post here once the issue is resolved. The repair cost me 695€.
