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.
Medium severity. Can I keep driving?If the car is running normally, drive in moderation to a repair shop. If it loses power or another warning appears, do not continue.
Symptoms
- Warning light on
- Harsh shifts and engagements
- Possible limp mode
Most likely causes
- Sensor ground open or poor terminal contact
- Signal wire shorted to 5 V reference or battery voltage
- Pressure sensor or solenoid pack failed internally
- Control module fault
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It can trigger limp mode.
- It affects emissions.
What each character of P0935 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 9: Transmission
- 35: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0935?
