I have a 1.6 DV6 2012 Citroen Berlingo. Situation is crank, non start after customer (another garage) carried out an engine change and camshaft position sensor signal fault code. One engine was from a ford fiesta, same year and same engine code. Both vehicles were running before engine swap but Citroen engine had bottom end knock and fiesta had a rear end shunt. Fault code clears and returns on 3rd revolution. I have verified power, ground and signal at the sensor. Doesn't start on external fuel source (brake cleaner) My thoughts are does the fiesta have a different sensor compared to the Citroen? Next step would be to verify wiring integrity at ECU? Cheers ๐๐ป.
