Checking the sensor cable for open
circuit or shortcircuit
Inlet manifold temperature sensor
Tools:
885675 Break-out cable
88890074 Multimeter
1 NOTICE! Cut the current with the main switch.
2
Disconnect the connector from the sensor
3
Connect break-out cable 885675 to the cable har-
ness connector to the engine control unit.
4 Remove connector A from the engine control unit.
5 Use multimeter 88890074 to do a resistance meas-
urement against engine control unit connector A.
Measurement points Nominal value
2 (885675)– 47(EMS2, conn.A) R ≈ 0 Ω
2 (885675)– 11(EMS2, conn.A) R ≈ ∞ Ω
1 (885675)– 47(EMS2, conn.A) R ≈ ∞ Ω
1 (885675)– 11(EMS2, conn.A) R ≈ 0 Ω
NOTICE! Measurement is done to eliminate short cir-
cuiting or
breaks in the cable to the engine control unit.
IMPORTANT!
Be very careful when measuring inside the connector,
to ensure that no pin is damaged.
