P0796 on Toyota
Pressure Control Solenoid 'C' Performance or Stuck Off
P0796 on Toyota vehicles indicates pressure control solenoid 'c' performance or stuck off. Au7o has documented this code across 1 Toyota model — most commonly on Land Cruiser. This generic transmission code means the TCM/PCM detected that pressure control solenoid 'C' is not regulating hydraulic pressure as expected, or appears stuck in the off position. These solenoids control the line pressure that applies the transmission's clutch packs to achieve the correct gear ratios, so a performance fault here disrupts shift quality. Symptoms can include harsh or delayed shifts, slipping, or limp mode, and continued driving can accelerate transmission wear.
Common Causes of P0796
- •Faulty pressure control solenoid C
- •Low, dirty, or degraded transmission fluid
- •Blocked or restricted valve body fluid passages
- •Damaged wiring or connector to the solenoid
- •Worn valve body or stuck valve
- •Internal transmission mechanical wear
- •Faulty TCM/PCM (rare)
P0796 on Toyota by Model
Toyota Land Cruiser(1 issue)
- Transmission Hesitation or Harsh Shift Behavior Requiring ECM/TCM Calibration Update2022-2023
Owners of the 300-series Land Cruiser and closely related TNGA-F Toyota/Lexus models have reported delayed engagement, low-speed hesitation, or abrupt 10-speed automatic shifts, especially when cold or during rolling stops. Toyota service literature for related powertrain calibration concerns points to software logic rather than hard-part failure in many cases. Complaints typically describe inconsistent throttle response paired with a sudden downshift or lurch.

What does P0796 mean on Toyota?▼
P0796 stands for "Pressure Control Solenoid 'C' Performance or Stuck Off." This generic transmission code means the TCM/PCM detected that pressure control solenoid 'C' is not regulating hydraulic pressure as expected, or appears stuck in the off position. These solenoids control the line pressure that applies the transmission's clutch packs to achieve the correct gear ratios, so a performance fault here disrupts shift quality. Symptoms can include harsh or delayed shifts, slipping, or limp mode, and continued driving can accelerate transmission wear. On Toyota specifically, this code is documented across 1 model.
What causes P0796 on Toyota vehicles?▼
Common causes on Toyota: Faulty pressure control solenoid C, Low, dirty, or degraded transmission fluid, Blocked or restricted valve body fluid passages, Damaged wiring or connector to the solenoid, Worn valve body or stuck valve. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0796 on a Toyota?▼
Repair costs vary widely depending on the root cause and specific Toyota model.
Which Toyota models have P0796 documented?▼
