DTC P1193 ETS LIMPHOME-Low Rpm: General Description

The ETSCM(Electronic Throttle System Control Module)is integrated with PCM(Powertrain Control Module). Therefore, Make sure that location of ETS Module is changed. The DTC P1193 is retrieved automatically when PCM detects a problem on the ETS. The Electronic Throttle System(ETS) consists of ETS-motor, Accelerator Position Sensor(APS), Throttle Position Sensor(TPS) and Limp home valve. Among above-mentioned parts, Limp home valve is attached under the throttle body and helps air to flow from the outside through this valve to the engine combustion chamber to prevent the vehicle from engine stall when PCM detects ETS system malfunction.
