Arkana Crankshaft Camshaft Error

My 2023 Renault Arkana with a gasoline engine is throwing a 'Crankshaft to Camshaft Reference Value' error. The check engine light is on, engine power is reduced, throttle response is laggy, and I seem to be burning more fuel. Mileage is at 221184 km. I suspect a faulty crank sensor, but has anyone dealt with this on a Renault before?

Summary of the thread

A 2023 Renault Arkana is experiencing a 'Crankshaft to Camshaft Reference Value' error, leading to reduced engine power, laggy throttle response, and increased fuel consumption. The issue is suspected to be caused by a faulty crank sensor. Possible causes include crankshaft/camshaft synchronization issues, a stretched timing belt, or wiring problems. The solution involved replacing the crank sensor, which resolved the error and restored normal vehicle performance.

The symptoms point toward crankshaft/camshaft synchronization issues. Have you checked the timing belt recently? Even if it looks okay, a slight stretch can throw off the timing enough to trigger that error and the performance problems.

I haven't inspected the timing belt, but it should be good for another 30k km according to the service schedule. You're right, a slightly stretched belt could cause the issue. If it's not the belt, and assuming the crank/cam sensors are working, what else could cause this sensor mismatch? I'm trying to avoid blindly replacing parts.

If timing belt integrity and sensor functionality are confirmed, inspect the wiring harness and connectors associated with the crank and cam sensors for corrosion or damage. Given the error code, it's probable one of the sensors is providing an inaccurate signal, or there is a mechanical timing issue. A workshop visit for deeper analysis is advisable.

It was the crank sensor – the readings were inconsistent. I replaced it, cleared the codes, and the Arkana is back to normal after spending 340€. Thanks for the help!
