What P0935 means
The pressure sensor signal sits above its valid window. On Chrysler RFE transmissions the line pressure sensor normally reads between 0.35 and 4.75 V; P0935 sets when the signal stays at or above 4.75 V for 0.18 s with the engine running. That pattern points to a signal wire shorted to the 5 V reference or to battery voltage, an open sensor ground or a sensor failed internally. An ALLDATA case on a 2003 Grand Cherokee logged it with P0932. Ferrari lists P0935 on its DCT as hydraulic pressure sensor signal too high. P0934 is the low counterpart, P0932 the general circuit fault, P0933 plausibility, P0936 intermittent. Expect harsh shifts and possibly a limp mode.

Symptoms of P0935
- Warning light on
- Harsh shifts and engagements
- Possible limp mode
Common causes of P0935
- Most likelySensor ground open or poor terminal contact
- PossibleSignal wire shorted to 5 V reference or battery voltage
- PossiblePressure sensor or solenoid pack failed internally
- Less likelyControl module fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0935 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 9 | Area: transmission. |
| 35 | The exact fault in that area. |
What to do next
- Note P0935 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0935
What does P0935 mean?
P0935 means "Hydraulic Pressure Sensor Circuit High". The pressure sensor signal sits above its valid window. It is a generic code, so it means the same on every make.
Is it safe to drive with P0935?
Drive gently and only to a workshop. With P0935 the car can go into limp mode (reduced power) to protect itself.
Will P0935 fail an emissions test?
Yes, it can. P0935 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0935 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0935 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
