P2816 on Toyota
Pressure Control Solenoid "H" Malfunction
P2816 on Toyota vehicles indicates pressure control solenoid "h" malfunction. Au7o has documented this code across 1 Toyota model — most commonly on Tacoma. The transmission control module detected a fault with pressure control solenoid 'H'. Toyota's Tacoma AC8 bulletin carries this as P281671, 'Pressure Control Solenoid H Actuator Stuck' - the commanded solenoid state and the measured hydraulic pressure disagree, so the module concludes the valve is mechanically stuck. On the 2024 Tacoma i-FORCE 8-speed, P2816 appearing alongside P08BA, P2713, P2807, and P0740 is one of the fault sets that authorizes replacement of the complete transmission and torque converter under warranty.
Common Causes of P2816
- •Pressure control solenoid 'H' stuck by debris or wear
- •Contaminated or overheated transmission fluid
- •Valve body wear or blocked hydraulic circuit
- •Open or shorted solenoid circuit / connector fault
- •Internal transmission hydraulic failure (Toyota AC8 - replaced as an assembly)

- i-FORCE 8-Speed Automatic (AC8) Transmission Failure Requiring Full Replacement (TSB T-SB-0076-24 / T-SB-0094-24)2024-2025
Early-production 4th-generation Tacomas with the 8-speed automatic transmission can suffer internal failure of the torque converter clutch actuator or pressure-control solenoids, often at very low mileage (some under 15,000 miles). Owners report harsh 1st-to-3rd-gear jerking, slipping, lunging, the truck dropping into neutral or getting stuck in gear, and sudden loss of drive. Toyota traced the cause to a stuck pressure-control solenoid actuator or torque-converter-clutch actuator (with manufacturing debris suspected) and issued TSB T-SB-0076-24, superseded by T-SB-0094-24 which added the Hybrid (i-FORCE MAX). The fix is not a calibration but a complete transmission and torque-converter replacement.
