P2110 Volvo Throttle Actuator Control System – Forced Limited RPM
If a malfunction occurs in the Electronic Throttle Control(ETC) system, the Engine Control Moduel (ECM) will control the enginefrom predetermined data stored in its memory or stop the engine if a safety problem is anticipated,as an Emergency Operation(Limp-Home)mode. The purpose of Limp-Home mode is to control the engine as close as possible to normal engine operation if a malfunction occurs. When the DTC related to ETC system is recorded by the ECM, then this DTC will be set. This DTC only indicates malfunction related to ETC system has occurred and engine is in Limp-Home mode. DO ALL REPAIRS Volvo associated malfunction with ETC system.
ECM sets DTC P2110 Volvo to indicate ETC system malfunction has occurred and engine is in Limp-Home mode. The ECM limits engine speed to 1500rpm after setting the DTC, as an Emergency Operation(Limp-Home)mode
