P0933Hydraulic Pressure Sensor Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- The pressure reading is electrically valid but does not fit the operating state. Chrysler RFE, RLE and TES transmissions set it when measured line pressure is more than 25 psi (172 kPa) above the commanded value while staying below the highest pressure ever used in that gear; Sonnax notes that a maximum-pressure condition from an open pressure control solenoid circuit can trigger it and mislead toward the sensor. Ferrari lists P0933 on its DCT as an invalid hydraulic pressure sensor signal, read in the NCR gearbox ECU. Neighbours: P0932, P0934 and P0935 are circuit faults, P0936 intermittent, P0869 a true high line pressure. The driver notices firm or harsh shifts.
- What you may notice
- Harsh or firm engagements and shifts
- Warning light on
- Shift quality does not adapt and may stay rough
- Likely causes
- LikelyOpen circuit or fault in the line pressure control solenoid causing real excess pressure
- PossiblePressure sensor drifting or reading offset
- PossibleWorn or sticking valves in the valve body
- RareWrong fluid level or degraded fluid
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
