Sequoia Hybrid Check Engine Light Power Loss

The symptoms you describe could indeed point to an issue with the crankshaft to camshaft reference. It's a critical parameter for engine timing. Has the vehicle undergone any recent maintenance or experienced any unusual events, such as rough idling or stalling, prior to the onset of these symptoms? A defective crankshaft position sensor can certainly cause these issues, but a diagnostic scan would be required to confirm the root cause.

Thanks for the quick reply! No recent maintenance, and no rough idling or stalling, just the engine light and power loss. So, if it is the crank sensor, is that a big job to fix? And if the timing chain is off, would that cause the same issues?

Given the absence of recent maintenance or other triggering events, the crankshaft position sensor remains a likely suspect. While replacing the sensor itself isn't excessively complex, proper diagnosis is paramount to ensure it's not a symptom of a deeper issue, such as timing chain wear. Deviations in the crankshaft to camshaft reference value often trigger the check engine light. I would advise consulting a qualified technician for a comprehensive evaluation of the system before proceeding with any repairs.

Okay, thanks so much for the advice. I took it to the shop, and you were right! The crank sensor was indeed defective. The repair cost me 340€. Runs like new again!
