What P0936 means
The hydraulic pressure signal drops out or jumps for short periods, too briefly or irregularly for a lasting low or high fault. No manufacturer documents this code publicly. The underlying sensor is the same one Chrysler uses for line pressure on RFE units and Ferrari for system pressure on its DCT, where the steady faults appear as P0934 and P0935. Gears Magazine names poor solder joints and crimps at the sensor terminals as a frequent source of intermittent pressure sensor codes. CARB requires circuit checks on such transmission inputs. P0932 to P0935 cover the general, plausibility, low and high faults. The driver may see a warning that comes and goes and occasional harsh shifts.

Symptoms of P0936
- Warning light comes and goes
- Occasional harsh or erratic shifts
Common causes of P0936
- Most likelyPoor crimp or solder joint at the sensor connector
- PossibleChafed harness making intermittent contact
- PossibleMoisture or corrosion in the connector
- Less likelySensor with an internal intermittent fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0936 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. |
| 36 | The exact fault in that area. |
What to do next
- Note P0936 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 P0936
What does P0936 mean?
P0936 means "Hydraulic Pressure Sensor Circuit Intermittent". The hydraulic pressure signal drops out or jumps for short periods, too briefly or irregularly for a lasting low or high fault. It is a generic code, so it means the same on every make.
Is it safe to drive with P0936?
Drive gently and only to a workshop. With P0936 the car can go into limp mode (reduced power) to protect itself.
Will P0936 fail an emissions test?
Yes, it can. P0936 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 P0936 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P0936 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.
