SYMPTOM
P1756 - GOVERNOR PRESSURE 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 temperature 10 - 127 °C (50 - 260 °F) .

POSSIBLE CAUSES
- Powertrain Control Module
- Check transmission fluid level and condition
- 5 Volt supply circuit open
- 5 Volt supply circuit open inside transmission
- Governor pressure sensor signal circuit open
- Governor pressure sensor signal circuit open inside transmission
- Governor pressure sensor signal circuit shorted to voltage
- Governor pressure sensor signal circuit shorted to voltage inside transmission
- Governor pressure sensor signal circuit shorted to ground
- Governor pressure sensor signal circuit shorted to ground inside transmission
- Governor pressure sensor signal circuit shorted to sensor ground
- Governor pressure sensor signal circuit shorted to sensor ground inside transmission
- Governor pressure sensor ground circuit open
- Governor pressure sensor ground circuit open inside transmission
- Intermittent governor pressure solenoid
- Internal transmission problem
- Oil burnt or oil pan has excessive debris
- Other transmission DTC's
- Valve body
- Governor pressure sensor (high)
