P07B0 Transmission Friction Element H Performance/Stuck Off

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

Each friction element (clutch or brake) has three functional codes: slip while commanded locked (P079A ff), performance/stuck off – it does not apply or applies too weakly – and stuck on – it does not release. No manufacturer document available to us uses this code: the documented hybrids have at most five monitored clutches. The description follows the family. A clutch that does not apply means a missing gear or slip, typically from worn plates, low pressure or a sticking valve. P07B0 belongs to element H; the same element's stuck-on code is P07B1, its slip P07A1 and its apply time P273B.

Likely causes

Clutch H plates worn or piston seal leaking
Too little apply pressure (fluid, pump, valve)
Clutch actuator or valve sticking (DCT: electric actuator)
Module software or lost adaption

Symptoms

  • Check engine light or transmission warning
  • Gear missing or slipping, weak acceleration
  • Limp mode
