Thanks Colin. The thing is , the car isn't running properly , but I think ill check all the earths, continuity as a starting point . do you know if any of the sensors share any supplies / earths in common . Or any good places to start on the electrical side with regards to cabling / connections on the ECU itself , or any fuses that could relate to this issue . I cant help thinking that the recent wet weather may have had something to do with it
All four cam and crank position plus knock sensors connect directly to the PCM (powertrain control module). The four camshaft control solenoids share a common positive supply via fuse 13 (15 amp) in engine fuse box, in turn fed by the PCM main relay, triggers are on negative side from PCM. This common supply connects to the solenoids via a single cable connector C58 in the engine loom, with white/yellow cable from relay and light green cable out to solenoids (there is a splice in this single cable to feed all four solenoids plus evap cannister purge valve). A few common sources to check therefore.
