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 GOV press 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).
