Tests 2 - 6:

Tests 7 - 12:

SYMPTOM
P1296 NO 5 VOLTS TO MAP SENSOR

TEST NOTE
This symptom is diagnosed using the test P0107 MAP SENSOR VOLTAGE TOO LOW.

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

SET CONDITION
The MAP sensor signal voltage goes below 2.35 volts with key ON 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 defect
- MAP sensor signal circuit shorted to ground
- MAP sensor signal circuit shorted to sensor ground circuit
- MAP sensor wiring harness/connectors intermittent defect
- MAP sensor defective
- PCM (5-volt supply circuit)
- PCM (5-volt supply circuit voltage low)
