Test
Engine Oil Level Sensor Check
1 W ith the aid of an assistant, perform the following:
a W hilst holding the engine oil level and temperature sensor (1) in a level position, connect a digital ohmmeter using connector test adaptor kit J 35616-A to terminals A and C, refer to Figure 6C1-3 – 21.
b W ith the flat surface of the float (2) positioned at the bottom, ensure continuity does not exist.
c Push the float upwards so the magnetic pin (3), on the inside of the float (the side of the float with the flat side) contacts the engine oil level sensor. Check for continuity whilst holding the float in this position.

3 Refill the engine with engine oil, refer to 6A1 Engine Mechanical – V6.
4 Road test the vehicle and check for correct operation, taking particular note there is no engine oil leakage from the oil level and temperature sensor.
2.10 Engine Oil Pressure Sensor
To avoid personal injury, take care when
removing the engine oil pressure sensor
when the engine is hot. Allow the engine to
cool before performing this procedure.

Clean the area around the engine oil pressure
sensor before removal to avoid debris from
entering the engine.
2 Disconnect the wiring harness connector (1) from the engine oil pressure sensor. NOTE
A small amount of oil will drain from the oil filter
housing when the engine oil pressure sensor is
removed. Use a shop towel to absorb the oil.
3 Using special tool J 41712 or a 11/16" deep socket and socket bar, remove the engine oil pressure
sensor (1).
Figure 6C1-3 – 22
Reinstall
Reinstallation of the engine oil pressure sensor is the reverse of the removal procedure, noting the following:
1 Tighten the engine oil pressure sensor to the correct torque specification.
Engine oil pressure sensor
torque specification .................................12.0 – 14.0 Nm
2 Check the engine oil level and top up if necessary, refer to 6A1 Engine Mechanical – V6.
2.11 Evaporative Emission (EVAP) Canister Purge Valve Quick Connect Fittings
Disconnect
Clean the area around the evaporative
emission (EVAP) canister purge valve before
disconnecting the quick connect fitting to
avoid debris from entering EVAP canister
purge valve.

Test
To prevent component damage:
• Use connector test adaptor kit J 35616-A.
• When applying 12 V to a component,
always use a 3 A fused wire.
Resistance Check
1 Using a digital ohmmeter and connector test adaptor
kit J 35616-A, measure the resistance across
terminals 1 and 2.
2 Compare the reading against the specification.
3 If the resistance is not within specification, replace the EVAP canister purge valve.
EVAP canister purge valve
resistance @ 20°C .................................... 24.0 – 28.0 Ω
Figure 6C1-3 – 29
Functional Test
1 Attempt to blow air through the EVAP canister purge
valve inlet port (1). If air passes through the valve, the
valve is faulty and should be replaced.

2 Using connector test adaptor kit J 35616-A, connect a
12 V battery, an on / off switch and a 3 A fused wire to
the EVAP canister purge valve terminals as follows:
• Positive lead to terminal 1.
• Negative lead to terminal 2.
Figure 6C1-3 – 31
Do not apply 12 V to the EVAP canister purge
valve continuously for more than three
seconds as the EVAP canister purge valve
will be damaged.
3 Turn the switch on, and listen for an audible click as the EVAP canister purge valve operates. W hilst the switch is in the on position, blow air through the inlet port.
4 If no air passes through the EVAP canister purge valve, check the valve inlet and outlet ports for any obstructions and rectify if necessary. If there are no obstructions, replace the valve.
Reinstall
Reinstallation of the evaporative emission canister purge valve is the reverse of the removal procedure, noting the
following:
1 Connect the purge valve hose quick connect fittings, refer to 2.11 Evaporative Emission (EVAP) Canister Purge Valve Quick Connect Fittings.
2 Road test the vehicle and check for correct operation, taking particular note that no air leaks are evident.
