P08BA on 2024-2025 Toyota Tacoma (SR, SR5, TRD Sport, TRD Off-Road, Limited, TRD Pro, Trailhunter) — Pressure Control Solenoid "L" Actuator Stuck
1 vehicles · 1 makes
Most Reported On
P08BA is an OBD-II diagnostic trouble code meaning “Pressure Control Solenoid "L" Actuator Stuck.” The transmission control module commanded pressure control solenoid "L" to change state and the resulting line/clutch pressure did not respond as expected, so the module concluded the solenoid valve is mechanically stuck rather than electrically open. Toyota's Tacoma bulletin lists this as sub-code P08BA71 (Pressure Control Solenoid 'L' Actuator Stuck) among the fault set that authorizes replacement of the complete 8-speed automatic (AC8) transmission and torque converter. This code is most commonly reported on 2024-2025 Toyota Tacoma (SR, SR5, TRD Sport, TRD Off-Road, Limited, TRD Pro, Trailhunter).

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
