Just coming in the middle of the movie, but;
Do you observe the compressor engage, indicating that the fused clutch engage voltage is good? (fuse'B' in the power dist.block.)
The relay coil votage comes from fuse 21 in the dash block.
The pressure transducer is not a switch- be CAREFUL shorting out plugs! (I discovered this the hard way) Anyway, the black/light blue wire is sensor ground- which isn't REALLY vehicle
ground- just a common data path for all the sensors.
The dark blue wire is transducer SIGNAL- a 5v or less input to
The 5v. signal voltage comes from the PCM on the remaing violet/white wire, into the transducer,which (I believe) is a pressure-variable resistor, giving the PCM data on the changing
the 'open' (disconnected) state may or may not confuse the PCM,
but I think jumping the full 5v signal to the PCM would definately
exceed range limit (voltage) it's expecting to see. Damn thinking boxes!
Hope this helps
