Hi

Thought this was going to be a quick one! checked resistances across sensor found one side open circuit. Fitted replacement FuelParts sensor fault still present even though scoping sensor showed sensor functioning referring to Autodata specimen waveforms. Carried out continuity between ECU and sensor, no shorts or opens. As cam belt a little tired I replaced belt, tensioner and guides and checked that TDC mark in crank pulley was accurate. Stumped now.
