Connect a DMM between the each position sensor
signal circuit (pins 2, 3 and 4 of E-2) and a known
good ground.
Is there circuit which did not voltage reading
within the specified value?
4.0 to 6.0
volts
Go to Step 14 Go to Step 11

1. Test the position sensor signal circuits
between the VNT control module (pins 1, 2
and 3 of E-4) and the actuator & sensor (pins
2, 3 and 4 of E-2) for a short circuit each other.
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?
Go to Step 20 Go to Step 12

Connect a DMM across the position sensor
reference voltage circuit and the low reference
circuit (pins 1 and 5 of E-2).
Is the DMM voltage more than the specified
value?
8.0 to 10.0
volts
Go to Step 16 Go to Step 15
13
1. Test the position sensor reference voltage
circuit between the VNT control module (pin 8
of E-4) and the actuator & sensor (pin 1 of E-
2) for the following conditions:
An open circuit
A short to ground
A short to the low reference circuit
A short to battery or ignition voltage
High resistance
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?
Go to Step 20 Go to Step 17

1. Test the position sensor signal circuits (which
ever voltage reading did not read within the
specified value at Step 10) between the VNT
control module (pins 1, 2 and 3 of E-4) and the
actuator & sensor (pins 2, 3 and 4 of E-2) for
the following conditions:
An open circuit
A short to ground
A short to the low reference circuit
A short to the reference voltage circuit
A short to battery or ignition voltage
High resistance
