What P08BA means
Base code for the twelfth pressure control solenoid of an automatic transmission; which valve carries the letter L is up to the manufacturer. Toyota is the one documented user: bulletin T-SB-0094-24 for the 2024 Tacoma and Tacoma Hybrid lists it as P08BA71, actuator stuck, next to the stuck faults of solenoids A, C, D, G and H and a torque converter clutch stuck off. Because Toyota reports the fault type through the suffix, the stuck valve sits under this base code rather than under P08BB/P08BC. The MIL comes on. For trucks built before the production change Toyota's fix is a new transmission with torque converter, on the hybrid also the hybrid module. GM's Corvette dual clutch tables contain no L code.
P08BA at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 7 hours
- Clears after repairAfter a drive cycle
Symptoms of P08BA
- Check engine light on
- Harsh, delayed or missing shifts
- Transmission may hold a substitute gear
Common causes of P08BA
- Most likelySolenoid or its control valve sticking inside the valve body
- PossibleInternal transmission fault from production, debris spreading through the hydraulics
- PossibleContaminated or wrong transmission fluid
- Less likelyConnector or harness fault at the solenoid
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P08BA means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 8 | Area: transmission. |
| BA | The exact fault in that area. |
What to do next
- Note P08BA and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P08BA
What does P08BA mean?
P08BA means "Pressure Control Solenoid L". Base code for the twelfth pressure control solenoid of an automatic transmission; which valve carries the letter L is up to the manufacturer. It is a generic code, so it means the same on every make.
Is it safe to drive with P08BA?
Drive gently and only to a workshop. With P08BA the car can go into limp mode (reduced power) to protect itself.
Will P08BA fail an emissions test?
Yes, it can. P08BA is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P08BA to fix?
Difficulty: workshop only. A typical repair takes 1 to 7 hours of work. This is a job for a workshop.
Will P08BA clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
