Crankshaft Sensor Error
Summary of the thread
The conversation revolves around a 2000 Lexus SC experiencing reduced engine power, poor response, and higher fuel consumption, with a diagnostic scan revealing a 'Crankshaft to camshaft reference value' error. The initial suspicion was a defective crankshaft sensor, but a worn or misaligned timing belt was also considered a potential cause. Ultimately, the issue was confirmed to be a defective crankshaft sensor, which was replaced, resolving the problem and restoring the car's performance.

Timing belt? I thought the crankshaft sensor was the likely culprit. How can I tell if the timing belt is the problem?

Well, a faulty sensor is possible. But a worn timing belt can slip and cause a similar reference error. Honestly, it's hard to diagnose without proper tools. Given the symptoms, I'd take it to a workshop for a proper diagnostic.

Thanks, I took it to a workshop as you suggested. Turns out the crankshaft sensor was defective after all. The repair cost 340€ and now the car is running smoothly again.

Sounds familiar. I had a similar issue with my SC. Have you checked the timing belt? A misaligned or worn timing belt can also throw off the crankshaft/camshaft reference and trigger those symptoms.
