P1196 Isuzu Description

The Electronic Throttle System (ETS) consists of ETS unit, 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 Powertrain Control Module (PCM) detects ETS system malfunction.
