1. Turn OFF the ignition.
2. Connect a DMM between the 5 volts reference
circuit of the vacuum pressure sensor harness
(pin 3 of C-124 connector) and a known good
ground.
3. Turn ON the ignition, with the engine OFF.
Is the DMM voltage more than the specified value?
5.5 volts

Important:
The vacuum pressure sensor may be
damaged if the sensor signal circuit is shorted to a
voltage source.
1. Test the signal circuit between the engine control
module (ECM) (pin 4 of C-57 connector) and the
vacuum pressure sensor (pin 1 of C-124
connector) for the following conditions:
•
A short to battery or ignition voltage
•
A short to any 5 volts reference
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?
Go to Step 13
Go to Step 12
7
1. Test the low reference circuit between the ECM
(pin 15 of C-57 connector) and the vacuum
pressure sensor (pin 2 of C-124 connector) for
an open circuit or high resistance.
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?

Go to Step 10
8
1. Test the 5 volts reference circuit between the
ECM (pin 1 of C-57 connector) and the vacuum
pressure sensor (pin 3 of C-124 connector) for a
short to battery or ignition voltage.
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?
Go to Step 13
Go to Step 12
9
1. Turn OFF the ignition.
2. Inspect for an intermittent and for a poor
connection at the harness connector of the
vacuum pressure sensor (pin 2 of C-124
connector).
3. Repair the connection(s) as necessary.
Did you find and correct the condition?
Go to Step 13
Go to Step 11
10
1. Turn OFF the ignition.
2. Disconnect the ECM harness connector.
3. Inspect for an intermittent and for a poor
connection on the vacuum pressure sensor
circuit at the harness connector of the ECM (pin
15 of C-57 connector).
4. Repair the connection(s) as necessary.
Did you find and correct the condition?
Go to Step 13
Go to Step 12
11
Replace the vacuum pressure sensor. Refer to
Vacuum Pressure Sensor Replacement in this
section.
Did you complete the replacement?
Go to Step 13
12
Important:
Replacement ECM must be
programmed.
Replace the ECM. Refer to Engine Control Module
(ECM) Replacement in this section.
Did you complete the replacement?
Go to Step 13
