I have seen lists and something I am seeing on my car is different from the list.
Of the lists I saw, this one from Mogolf seems to be the most thorough:
It supplies power to
- Glow plug relay
- Fuse 32
ECM
Fuel quantity adjuster
- Fuse 34
Cold start injector
Waste gate bypass regulator valve (N75)
Change over valve (N239)
EGR vacuum regulator valve (N18)
Mass air flow sensor (G70)
- Fuse 43
Clutch vacuum vent valve (if equipped)
Brake vacuum vent valve
Relays for preheating coolant (if equipped)
Crankcase ventilation heating element
The ECM supplies power (and sometime ground as well) for:
Fuel cutoff valve
Cruise control switch
Manifold (intake) air pressure/Intake air temperature sensor
Needle lift sensor
Engine speed sensor
Engine coolant sensor
Closed throttle position switch (part of "go" pedal)
Kickdown switch (part of "go" pedal)
Throttle position switch (part of "go" pedal)
Fuel temperature sensor
Modulating piston displacement sensor
My problem is this... my fuse 34 is NOT being powered by my relay 109. I have 12v at that fuse regardless of whether the relay 109 is even installed. I have a 99 nb, so this may be a change that has gone on over time... but is my car showing the signs of ..... a short to hot some where?
