What P0932 means
General electrical fault in the circuit of the sensor that reports hydraulic pressure in the transmission, usually line pressure in an automatic or system pressure in an automated manual or dual-clutch unit.
How the engine computer detects it
The module sees a signal it cannot use at all, without a clear low or high pattern. Chrysler names it Line Pressure Sensor Circuit Fault; an ALLDATA case on a 2003 Grand Cherokee 4.7 automatic shows it together with P0935, caused by an open line pressure solenoid in the solenoid pack. CARB requires circuit checks on such transmission inputs. P0934 and P0935 are the low and high faults, P0933 the plausibility fault, P0936 the intermittent one. Expect harsh shifts, often with line pressure forced to maximum.
Written from public technical sources and not yet checked by a mechanic. How we write these pages
Symptoms
- Warning light or transmission warning on
- Harsh engagements and firm shifts from maximum line pressure
- Possible limp mode with limited gears
Common causes
- Fault in the solenoid pack or valve body module that carries the pressure sensor (open solenoid, internal lead frame) Most likely
- Poor crimp or solder joint at the sensor connector terminals Possible
- 5 V reference or sensor ground interrupted Possible
- Transmission or powertrain control module fault Less likely
How to diagnose P0932
- Read every stored code with an OBD-II scanner. If misfire or fuel trim codes are there too, fix those first: they often cause this one.
- Inspect the parts involved: hydraulic pressure sensor, wiring harness, tcm.
- Work through the causes above from most to least likely, cheapest checks first.
- Clear the code and drive a full drive cycle to confirm the repair held.

Questions drivers ask
Can I drive with code P0932?
Drive gently and only as far as you need to. The engine computer may limit power to protect the engine, so avoid highways and heavy traffic until it's fixed. If the check engine light starts flashing, pull over.
Will my car pass an emissions inspection with P0932?
Probably not in states that test vehicles with an OBD-II scan: an emissions-related code that keeps the check engine light on is usually an automatic fail. Rules differ by state and county, so check yours.
