Durango 4WD V8-5.9L VIN Z (1998)
2. Test the MAP sensor output voltage at the MAP sensor connector between terminals A and B (Fig. 51). With the ignition switch ON and the
engine OFF output voltage should be 4-to-5 volts. The voltage should drop to 1.5-to-2.1 volts with a hot, neutral idle speed condition.
3. Test powertrain control module (PCM) cavity A-27 for the same voltage described above to verify the wire harness condition. Repair as necessary
4. Test MAP sensor supply voltage at sensor connector between terminals A and C (Fig. 51) with the ignition ON.
-
The voltage should be approximately 5 volts (+/- 0.5V).
-
Five volts (+/- 0.5V) should also be at cavity A-17 of the PCM wire harness connector.
-
Repair or replace the wire harness as necessary.
5. Test the MAP sensor ground circuit at sensor connector terminal A (Fig. 51) and PCM connector A-4.
-
Repair the wire harness if necessary
