Top quality and Inexpensive Jeep PCM and ECM Parts
  • The Powertrain Control Module abbreviated as PCM is put in the engine area. PCM is also described as JTEC which is Jeep/Truck Engine Controller. This can be a per-programmed triple microprocessor digital computer. The procedure of fuel system, regulating combustion timing, air-fuel ratio, emission control devices, several transmission features, charging system, control of speed, air conditioning compressor, clutch engagement and the dead speed, all of them are operated by the PCM. It is an important component.

    The input signals from different switches and sensors are sent to the Jeep PCM. Various engine and vehicle procedures are regulated through different system components by making use of PCM. All of these components are specified as Powertrain Control Module (PCM) Outputs. The switches and sensors which provide inputs to the PCM are known as Powertrain Control Module (PCM) Inputs.

    The PCM assists with adjusting ignition timing which is structured after the inputs it receives from the sensors which react to engine rpm, engine coolant temperature, manifold absolute pressure, transmission gear selection (automatic transmission), throttle position, brake change and the speed of vehicle. PCM helps in adjusting the idle speed which is dependent on inputs, which it gets from the sensors.
