Frequently asked questions

What does the crankshaft position sensor do?
The crankshaft position sensor mounts at the crankshaft and reads the reluctor ring to track crankshaft angle and speed on the Jaguar AJ-series V8 (4.0L and 4.2L) petrol engine. The control module uses this signal to schedule ignition and injection timing. This is an Intermotor sensor.
What are the symptoms of a failing crank sensor?
A failing crankshaft position sensor typically causes a no-start, intermittent stalling, or a crank-signal fault code, since the ECM can't establish engine position without it. Failures often appear when hot then clear when cool, a common cause of erratic starting on the AJ V8.
How do I confirm it fits my Jaguar?
This sensor fits Jaguar XK8 (X100) 4.0L, S-TYPE (X200) V8, XJ (X308) 4.0L, XJ (X350) 3.5/4.2L, XF (X250) 4.2L up to VIN R47153 and XK (X150) 4.2L. For the XF, check your VIN against R47153 before ordering.
