SYMPTOM
P1756-GOVERNOR PRESS NOT EQUAL TO TARGET @ 15-20 PSI

WHEN MONITORED
Continuously with the key ON and the engine running.

SET CONDITION
This code will set if the Governor pressure sensor output is < 103 KPa (15 PSI) or > 207 KPa (30 PSI) when the requested pressure is 138-172 KPa (20-25 PSI) for 2.2 seconds. Two trips of five consecutive bad 2.2 second tests with sump temp 10-127 °C (50-260 °F).

POSSIBLE CAUSES
- Other transmission DTC'S
- Intermittent governor pressure solenoid
- Check trans fluid level and condition
- 5 Volt supply circuit open
- GOVERNOR pressure sensor signal circuit open
- Sensor ground circuit open
- Governor pressure sensor signal circuit short to ground
- Governor pressure sensor signal circuit short to sensor ground
- Governor pressure sensor signal circuit short to voltage
- 5 Volt supply circuit open inside trans
- Governor pressure sensor ground circuit open inside trans
- Governor pressure sensor signal circuit open inside trans
- Governor pressure sensor signal circuit short to ground inside trans
- Governor pressure sensor signal circuit short to sensor ground inside trans
- Governor pressure sensor signal circuit short to voltage inside trans
- Oil burnt or oil pan has excessive debris
- valve body
- Governor pressure sensor
- Internal transmission
- PCM - 5 Volt SUPPLY
- PCM - GOVERNOR pressure not equal to target
