P282B
Pressure Control Solenoid K Electrical
Transmission
Generic OBD-II
Medium
What it means
P282B means the transmission controller detects an electrical fault — an open, short, or out-of-range resistance — in the pressure control solenoid K circuit. Unlike a mechanical "stuck" fault, this points at the wiring, connector, or solenoid coil. The transmission commonly enters limp mode with harsh or fixed-gear shifting until the circuit is repaired.
Medium
Can I keep driving? Limited — the transmission often drops into limp mode with harsh or fixed-gear shifting; drive gently and fix soon.
Common symptoms
What you'll notice
- Check-engine light on
- Harsh, delayed, or missing shifts
- Transmission enters limp/failsafe mode
- Erratic shift behavior
Common causes
Most likely first
- Open or short in the pressure control solenoid K circuitLikely
- Failed solenoid coil (resistance out of spec)Common
- Corroded or damaged connector at the transmissionCommon
- Internal transmission (case connector) harness faultLess often
- TCM output-driver fault (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and inspect the transmission case connector and wiring.
- Measure solenoid K resistance against spec.
- Check the circuit for opens or shorts to power/ground.
- Repair the wiring or replace the solenoid, then clear and retest.
FAQ
Quick answers
Is it safe to drive with P282B?+
Only gently. This is an electrical fault in the solenoid circuit, and the transmission usually enters limp mode to protect itself, which limits shifting.
Can I just clear P282B?+
It returns immediately if the wiring or solenoid is faulty, since the controller continuously monitors the solenoid's electrical circuit.
