SYMPTOM
P1764 - GOVERNOR PRESSURE SENSOR VOLTS TOO LOW

WHEN MONITORED
Continuously with the key ON and engine running.

SET CONDITION
The voltage from the Governor Pressure Sensor is below 0.10 volts for 8.5 seconds.

POSSIBLE CAUSES
- 5 volt supply circuit open
- Governor pressure sensor ground circuit open
- Governor pressure/temperature sensor
- Governor pressure sensor signal circuit shorted to sensor ground circuit
- Governor pressure sensor wiring harness intermittent defect
- Governor pressure sensor wiring harness observable defect
- Governor pressure sensor signal circuit shorted to ground
- Governor pressure sensor signal circuit shorted to voltage
- Governor pressure sensor signal circuit open
- Transmission harness/solenoid assembly (ground)
- Transmission harness/solenoid assembly (sensor ground)
- Transmission harness/solenoid (signal circuit > 5.0 ohms)
- Transmission harness/solenoid assembly (signal resistance)
- Governor pressure/temperature sensor
- Powertrain Control Module
- Transmission harness/solenoid (ground circuit > 5.0 ohms)
- Transmission harness/solenoid (signal circuit > 1.0 volt)
- Transmission harness/solenoid assembly (ground resistance)
- Transmission harness/solenoid assembly
