In order to regulate hydraulic pressure inside of the transmission, the transmission control module uses an electric plunger device known as a pressure control solenoid. If the voltage from the power circuit on the solenoid is unusually high, a P1832 diagnostic trouble code will be stored.
How Serious is the Code?
The P1832 DTC is extremely serious, because it cannot only render the vehicle undrivable. But the hydraulic pressure fluctuations can cause significant damage to the internal components.
Symptoms of a P1832 include:
- Transmission won’t shift into or out of a gear
- Limp Mode
- Transmission overheating
- Check engine light
- Faulty pressure control solenoid
- Damaged wiring
- Clogged hydraulic passages
How to Diagnose the Code?
In order to properly diagnose a P1832 OBDII diagnostic trouble code, a mechanic should first look at the condition of the transmission fluid. Old or dirty transmission fluid can cause hydraulic passages to become clogged, which could affect the performance of the pressure control solenoid. Should the ATF be in good condition, then electrical and pressure tests will need to be performed to confirm a faulty pressure control solenoid.
What Repairs Will Fix P1832?
- Perform transmission flush/change transmission fluid/filter
- Replace pressure control solenoid
- Repair damaged wiring
