hi can anyone tell me what's happening to my timing or valves got fault code p1000 thanks in advance 4.6 Thor 1999

I think the code is telling you the answer.......

Check the cam sensor is seated correctly, the wiring is secure and not chaffed.

The timing is set by a chain and sprockets, while chains can stretch and alter the timing by a fraction, it wont be 'out of time' ..... But if the ecu doesnt get a signal from the cam sensor, it will default the ingnition and injection times to a default map and use the crank sensor for baseline timing purposes.

Thanks saint will check the wires
