Some testing resistances for a few of the Engine Devices (to be used in other posts)

[UrS4boy]

2-pin Devices (test across the two male pins of the devices):

Injectors = 15 to 17 Ohms
G42 Intake Air Temp = 450 to 650 Ohms at 20 C
G62 Engine Coolant Temp (at 20 C) = 1500 to 3000 Ohms
N71 ISV = 7 to 11 Ohms
N75 WGFV = 25 to 35 Ohms
N80 Evaporative Emissions Control Valve = 40 to 50 Ohms


3 pin Devices:

G4 Crank Position Sensor:

1 to 2 where 1 = left of the __/\__ = 1000 ohms
1 to 3 = should be open
2 to 3 = should be open

G28 Engine Speed Sensor:

1 to 2 where 1 = left of the __/\__ = 1000 ohms
1 to 3 = should be open
2 to 3 = should be open

This should be a sticky.

Cheers Dave, very useful, I've used some of the data already.
