P0782 — Pressure Control Solenoid B Electrical
Drivable short-term, but fix now to avoid damage.
What P0782 means
This code means the transmission control module detected an electrical fault in the circuit for pressure control solenoid B, such as an open, short, or out-of-range signal. It's commonly caused by damaged wiring, corroded connectors, or a failed solenoid. Typical fixes include repairing or replacing the wiring and connectors, or replacing the solenoid itself.
Common symptoms
- Check engine light is on
- Erratic or harsh shifting
- Transmission slipping
- Vehicle enters limp mode
- Transmission warning indicator may appear
Common causes
- Damaged or corroded solenoid wiring
- Loose or faulty electrical connectors
- Failed pressure control solenoid B
- Short or open circuit in the solenoid harness
- Faulty transmission control module
Typical repair cost
$150 – $650
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0782 code?
For short trips usually yes, but don't rely on it. An electrical fault can cause sudden shifting problems or limp mode, so get it checked soon to avoid being stranded.
How much does it cost to fix a P0782 code?
Repairs typically run from about $150 to $650. A wiring or connector fix is on the lower end, while replacing the solenoid increases the cost.
Is a P0782 code serious?
It can be. Although it sometimes traces to simple wiring, the transmission may enter limp mode, so it's best to diagnose and repair it without delay.
Could this just be a wiring issue rather than a bad solenoid?
Yes, electrical codes like this often come from damaged wires or corroded connectors, so a good technician will test the circuit before replacing the solenoid.
