ANY TECH HELP!

[Richyl398]

Anyone please help. Have a 2007 1.6i focus. Have had the dashboard repaired. Hasn't worked. The rev counter works on start up and drops straight to zero and the engine light is on with a crank sensor fault. I've changed the sensor and it all resets but the light comes back on? So no rev counter and a crank sensor fault with intermittent abs sensor fault light to. Help anyone?

There might be the a problem with the plug or wiring from the sensor back to the pcm. Did it make any difference when the crank sensor was changed?

Another possibility is the camshaft sensor. There can be cases where a fault in one of these two is detected by the car as a fault in the other, since the two are compared.

If you are using a generic OBD scanner, then it is possible that a Ford specific scanner like Forscan will pick up other error messages, there could still be a communications problem between the IC and the pcm. That would stack up with the ABS error. There are several connectors in that link. One in the engine bay fusebox, two in front of the passenger door, and the ones on the IC and the pcm.
