P0935 Hydraulic Pressure Sensor Circuit High

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.

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

Symptoms

  • Warning light on
  • Harsh shifts and engagements
