Crown Crankshaft to Camshaft Reference Value Issue

Hello. I'm experiencing a strange issue with my 2004 Toyota Crown with a gasoline engine. The check engine light is on, and the car feels like it has reduced engine power. The engine response is poor, and I've noticed higher fuel consumption recently. The error code points towards a 'Crankshaft to Camshaft Reference Value' issue. Could a defective crank sensor cause these symptoms?

I had a similar issue with my old Opel Astra; the symptoms sound familiar. The crank sensor went bad, and it messed up the engine synchronization. Have you checked the timing belt or chain? A stretched or damaged timing belt can cause similar problems and throw off the crankshaft to camshaft timing.

Thanks for the quick reply. How did you pinpoint the crank sensor on your Opel? And how did you check your timing? I wouldn't know where to start. The car has only 57120 km on it.

On the Astra, the diagnostic tool showed an intermittent signal from the crank sensor. Given your symptoms and the error code, it's highly likely to be the crank sensor on your Crown too. But with such a low mileage the timing belt should be fine. Still, I would recommend having a workshop take a look and confirm the diagnosis. It is better to be safe than sorry.

Thanks for the confirmation. I took it to a shop; you were right. It was indeed the crank sensor. The sensor replacement and diagnostics cost me 340€. Now the Crown is running smoothly again.
