Hi just throwing this out here for pointers as I'm missing something
OK I have the grand espace v6 3.0 diesel
Over the holiday I removed the engine and changed the head gaskets
I have put the engine back in but now it won't start
it starts for a second then cuts out
it gives a fault code of cam sensor with 3 examples
1- cam sensor open circuit
2- cam sensor signal incomprehensible
3- cam sensor signal incomprehensible with engine speed
So I have checked - cam timing , pump timing , all top dead centre marks ,
Removed timing belt again and again checked everything is lined up via auto data
replaced both crank and cam sensors
made a part loom from sensors to ECU ( it is a renault )
And still I get this fault code
I have tried new feeds to sensors
and independent earth's
the sensors are quite simple as in two wires - signal and earth
the car drove to my lockup (but was pushing water from header hence head gaskets )
I'm now lost
I'm missing something -but just can't see it
the fault code was not present before removing engine
