Volvo All Engines (2017 Emissions) Fault Code: P115000 PID: EMS Throttle/Pedal Position Sensor/Switch “A/D” Voltage Correlation
Volvo All Engines (2017 Emissions) Fault Code: P115000 PID: EMS Throttle/Pedal Position Sensor/Switch “A/D” Voltage Correlation
An analog signal from the accelerator pedal is used to indicate a percent value of the accelerator pedal position. The signal is monitored by the Vehicle Electronic Control Unit (VECU) and communicated to the Engine Control Module (ECM) via the J1939 data link. Based on the signal, the ECM will request a certain engine torque. If the analog signal is too low or too high, the ECM instead uses the digital signal from the accelerator pedal’s idle validation switch to enable driving in limp home mode.
Conditions for diagnostic trouble code (DTC):
1) No signal : Idle validation switch IVS 2
2) 0-22% : Accelerator pedal
Observable symptoms
1) The engine does not respond when accelerator pedal is pressed.
Probable cause
1) Wiring harness between sensor connector and Engine Control Module (ECM)
2) Connector
3) Accelerator pedal
4) Vehicle Control Unit (VECU)
