Volvo All Engines (2017 Emissions) Fault Code: P114113 PID: EMS Buffered Idle Validation Switch Wire – ECM Side

The Idle Validation Switch is open at the idle position and transmits no voltage to the (VECU) Vehicle Electronic Control Unit. At approximately 1-13% pedal position the Idle Validation Switch closes and completes the circuit to the (VECU) Vehicle Electronic Control Unit.
The (VECU) Vehicle Electronic Control Unit then sends a voltage signal to the Engine Control Module (ECM) indicating accelerator pedal position. If both communication links (J1939, J1587) are faulty the pedal demand functionality enters limp-home. During limp-home the (IVS) Idle Validation Switch is used for ramping requested torque.

Conditions for diagnostic trouble code (DTC):
1) Accelerator pedal pressed down more than 50 %

Probable cause
1) Open circuit on signal wire
2) Connector
3) Accelerator pedal

Detailed information
1) The limp home mode does not function
