What Does P1757 Mean?
The governor pressure sensor indicates more than 3 PSI of pressure when the system has commanded 0 PSI. This suggests a stuck solenoid, internal leak bypassing the control valve, or a faulty pressure sensor.
Common Causes
40%
Stuck open or contaminated governor pressure solenoid valve
25%
Failed governor pressure sensor reading incorrectly high
20%
Internal transmission hydraulic circuit leak or valve body malfunction
10%
Debris or contamination in valve body causing valve to stick
5%
Damaged pressure regulator valve or spring
Diagnostic Steps
1
Step 1: Monitor governor pressure sensor readings at idle with transmission in park/neutral
2
Step 2: Command governor pressure solenoid to 0% duty cycle and verify pressure drops
3
Step 3: Check transmission fluid for contamination or metal particles indicating internal damage
4
Step 4: Remove and inspect governor pressure solenoid for sticking or contamination
5
Step 5: Install mechanical pressure gauge to verify actual pressure versus sensor reading
Estimated Repair Cost
$180 - $1,500
Parts + labor, varies by vehicle and location
The governor pressure sensor indicates more than 3 PSI of pressure when the system has commanded 0 PSI. This suggests a stuck solenoid, internal leak bypassing the control valve, or a faulty pressure sensor.
The most common cause of P1757 (Governor Pressure Above 3 PSI When Request Is 0 PSI) is: Stuck open or contaminated governor pressure solenoid valve
Typical repair costs for P1757 range from $180 to $1,500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May result in harsh engagements, firm shifts, or inability to properly control line pressure. Can be driven carefully but requires prompt repair.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P1757 to identify the root cause.
