Tahoe Camshaft Sensor Failure

My 2022 Chevrolet Tahoe diesel has a rough start, stalls at idle, and the check engine light is on. The error code points to a defective camshaft sensor, and the mechanic suspects the encoder wheel on the camshafts. Has anyone else had this?

A 2022 Chevrolet Tahoe diesel experienced rough starts, stalling at idle, and an illuminated check engine light, with an error code indicating a defective camshaft sensor. The mechanic suspected the encoder wheel on the camshafts as the underlying issue. It was confirmed that the encoder wheel was defective, causing the sensor to fail. The recommended solution was to replace both the camshaft sensor and the encoder wheel, which resolved the problem.

I have a Tahoe, though not a 2022, and had similar issues recently. Check engine light and stalling. The camshaft sensor was the problem. It monitors the camshaft position, which is crucial for ignition timing and fuel injection. Sensor failure can cause those symptoms.

Thanks. Can you share details about the repair? Was the encoder wheel damaged, or just the sensor? Did you check the crankshaft sensor?

The encoder wheel was defective, which made the sensor fail. The mechanic suggested replacing both to prevent it from happening again. I didn't check the crankshaft sensor separately, but the diagnostic focused on the camshaft position. A trusted workshop should inspect and repair it. Replacing both the sensor and encoder wheel is the best idea.

Thanks for the advice. The shop confirmed the encoder wheel was the main problem, damaging the sensor. They replaced both, and it's fixed. Total cost was 695€.
