LS400 Electrics

[MotherTrucker]

What info can be obtained from the Diagnostic Port mounted on the top of a 1995 (UK registered) LS400 engine?

What equipment do I need to access the information?

Was a OBD type socket factory fitted to the 1995 LS400?

What Ohmic value should a healthy Camshaft Position Sensor measure?

Can anyone help me to source ECU wiring connection diagrams for this specific 1995 model?

Apologies for the number of questions but I need to find/fix a problem.

Thanks,

With there being a cam sensor on both cam gears you could measure both to see if they are the same value. If you do have a cam sensor fault it is quite common to find the wiring loom to the passenger side one damaged if it hasn’t been redressed correctly after a belt change....it can get chewed up by the serpentine belt.

Not too sure about the later model but earlier versions used a paperclip to read the codes by blinking lights sequences.

Also welcome to the LOC.
