P2E15 is the basic circuit code for the position sensor of a second selection actuator, one assigned to the intermediate shaft (layshaft) of the gearbox rather than to the main gear selection, which has P2E10 to P2E14. Which gearboxes use such an actuator, and what exactly it engages there, no manufacturer documents publicly for this code. Schaeffler's LuK paper on electric dual-clutch actuators shows the general idea: separate electric motors handle the shift and the select movement, while the select motor moves the shift finger axially into the gate that is needed. The control module needs the position feedback to know whether the selection has been made. CARB requires circuit checks on such transmission sensors. If the signal fails electrically, gear changes that involve this shaft are blocked. P2E16 to P2E19 are the specific variants.

Likely causes

Connector or harness to the intermediate shaft actuator damaged or corroded
Position sensor of the actuator failed
Sensor supply or ground missing
Faulty input stage in the transmission control module

Symptoms

  • Transmission warning and MIL
  • Some gears unavailable or gearbox in limp mode
  • Vehicle may only drive in a restricted range of gears
