SYMPTOM LIST
P-1296 NO 5-VOLTS TO MAP SENSOR

TEST NOTE:
All symptoms listed above are diagnosed using the same tests. The title for the tests will be P-0107 MAP SENSOR VOLTAGE TOO LOW.

WHEN MONITORED
With the ignition off and battery voltage greater than 10.4 volts.

SET CONDITION
The MAP sensor signal voltage goes below 2.35 volts with key off for 5.0 seconds.

POSSIBLE CAUSES
- MAP sensor 5-volt supply circuit open
- MAP sensor 5-volt supply circuit shorted to ground
- MAP sensor harness/connectors observable def
- MAP sensor signal circuit shorted to ground
- MAP sensor signal circuit shorted to ground circuit
- MAP sensor wiring harness/connectors intermittent def
- MAP sensor defective
- PCM def (5-volt supply circuit ok)
- PCM def (5-volt supply circuit voltage low)
