2
  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 below the value specified?		 4.1 V Go to Step 3. Go to Step 4.
3
  1. Disconnect the vacuum line from the MAP sensor.
  2. Apply 60 kPa (17.7 inHg) 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 - 5.5 V 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?		 4.5 V Go to Step 13. Go to Step 11.
6 Measure the voltage between the MAP sensor connector terminal A and ground.
Does the voltage measure within the value specified?		 4.5 - 5.5 V Go to Step 7. Go to Step 8.
7
  1. Turn the ignition switch to LOCK.
  2. Check for open wires between the MAP sensor connector terminal A and the ECM connector terminal 65.

Is the problem found?		 - Go to Step 8. Go to Step 9.
8
  1. Repair the wire or the connector terminal between the MAP sensor connector terminal A and ECM connector terminal 65.
  2. Using the scan tool, clear the Diagnostic Trouble Codes (DTCs).
  3. Perform an On-Board Diagnostic (OBD) System Check.

Is the repair complete?		 - System OK -
9
  1. Turn the ignition switch to LOCK.
  2. Check for an open or short to ground in the wire between the MAP sensor connector terminal C and the ECM connector terminal 48.

Is the problem found?		 - Go to Step 10. Go to Step 11.
10
  1. Repair the wire or the connector terminal as needed.
  2. Clear any DTCs from the ECM.
  3. Perform the diagnostic system check.

Is the repair complete?		 - System OK -
11 Check for an open or short to ground in the wire between the MAP sensor connector terminal B and the ECM connector terminal 12.
Is the problem found?		 - Go to Step 12. Go to Step 14.
12
  1. Repair the wire or the connector terminal between MAP sensor connector terminal B and the ECM connector terminal 12.
  2. Using the scan tool, clear the Diagnostic Trouble Codes (DTCs).
  3. Perform an On-Board Diagnostic (OBD) System Check.

Is the repair complete?		 - System OK -
13
  1. Replace the MAP sensor.
  2. Using the scan tool, clear the Diagnostic Trouble Codes (DTCs).
  3. Perform an On-Board Diagnostic (OBD) System Check.

Is the repair complete?		 - System OK -
14
  1. Turn the ignition switch to LOCK.
  2. Replace the ECM.
  3. Perform an On-Board Diagnostic (OBD) System Check.

Is the repair complete?		 - System OK -
