P2880 is stored when the signal in the actuator circuit of the engine disconnect clutch stays below its permitted window. In practice this usually means a short to ground on the control side, or a feed that has lost supply voltage, so that the solenoid or actuator is either energised permanently or not at all, depending on which side is affected. The control module normally switches the output off to protect itself. No manufacturer publishes a description of this code; the circuit monitoring follows the general CARB demand that output components of the powertrain be checked for electrical faults. Whether the clutch then rests open or closed depends on its design; the Ford F-150 PowerBoost and the Audi plug-in hybrids use hydraulic clutches inside the transmission. Compare P2881 for the high side.

Likely causes

Chafed control wire shorted to ground or housing
Missing supply voltage (fuse, relay, feed wire)
Internal short in the clutch solenoid coil
Faulty output stage in the control module

Symptoms

  • Hybrid or transmission warning lamp
  • Engine cannot be coupled, only electric driving available
  • Limp-home mode after the output is switched off
