Component Inspection

Check performance test.

Ignition "OFF".
Remove the MAP sensor and connect MAP sensor connector.
Ignition "ON" & Engine "OFF".

Using s hand-held vacuum pump, apply vacuum and measure the "MAP SENSOR" parameter on scantool.

Specification:

VOLTAGE SPECIFICATION

Applied Vacuum	Output Voltage
10 kPa (100 mbar, 1.45 psi)	0.06V
5 kPa (150 mbar, 2.18 psi)	0.25V
40 kPa (400 mbar, 5.8 psi)	1.3V
80 kPa (800 mbar, 11.6 psi)	3V
120 kPa (1200 mbar, 17.4 psi)	4.8V

G07703449

Is the measured parameter displayed within specifications?
YES
- Go to " 2 Check PCM" as below.
NO
- Substitute with a known - good MAP and check for proper operation.
  If the problem is corrected, replace MAP and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

Check PCM.
1. Ignition "OFF".
2. Connect Scantool and Ignition "ON" & Engine "OFF".
3. Select simulation function on scantool.
4. Simulate voltage at terminal 1 of MAP sensor signal connector.

5. Does the signal value of MAP sensor changes according to simulation voltage?
  YES
  - Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage. Repair or replace as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
  NO
  - Substitute with a known - good PCM and check for proper operation.
    If the problem is corrected, replace PCM and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
