What P0933 means
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.
P0933 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 5 hours
- Clears after repairAfter a drive cycle
Symptoms of P0933
- Harsh or firm engagements and shifts
- Warning light on
- Shift quality does not adapt and may stay rough
Common causes of P0933
- Most 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
- Less likelyWrong fluid level or degraded fluid
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0933 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. |
| 33 | The exact fault in that area. |
What to do next
- Note P0933 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 P0933
What does P0933 mean?
P0933 means "Hydraulic Pressure Sensor Range/Performance". The pressure reading is electrically valid but does not fit the operating state. It is a generic code, so it means the same on every make.
Is it safe to drive with P0933?
Drive gently and only to a workshop. With P0933 the car can go into limp mode (reduced power) to protect itself.
Will P0933 fail an emissions test?
Yes, it can. P0933 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 P0933 to fix?
Difficulty: hard. A typical repair takes 1 to 5 hours of work. This is a job for a workshop.
Will P0933 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
