1. Connect the scan tool to the data link connector
(DLC).
2. Turn the ignition switch to ON.
Does the scan tool show the manifold absolute
pressure (MAP) sensor voltage above the value
specified? 4V Go to Step 3 Go to Step 4
3
1. Disconnect the vacuum line from the MAP
sensor.
2. Apply 66kPA (20in.of Hg) of vacuum to the MAP
sensor.
Does the scan tool show the MAP sensor voltage
within the value specified? 1.0–1.5V
Go to
“Diagnostic
Aids” Go to Step 4
4
1. Turn the ignition switch to LOCK.
2. Disconnect the MAP sensor connector.
3. Turn the ignition switch to ON.
4. Measure the voltage between the MAP sensor
connector terminals A and C.
Does the voltage measure within the value
specified? 4.5–5.0V Go to Step 5 Go to Step 6
5
Connect a fused jumper between the MAP sensor
connector terminals B and C.
Does the scan tool show the MAP sensor voltage
above the value specified? 4V Go to Step 11 Go to Step 9
6
Measure the voltage between the MAP sensor
connector terminal A and ground.
Does the voltage measure within the value
specified? 4.5–5.0V Go to Step 7 Go to Step 8

1. Turn the ignition switch to LOCK.
2. Check for open wires between the MAP sensor
connector terminal A and the ECM connector
terminal 78.
