Crankshaft Sensor Error

Hi, I have a 2000 Lexus SC with a gasoline engine. The check engine light is on, and I'm experiencing reduced engine power, poor response, and higher fuel consumption. Mileage is at 50979 km. I ran a scan and got a 'Crankshaft to camshaft reference value' error. Could a defective crankshaft sensor cause this?

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.

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.
