Good quality and Inexpensive Jeep PCM and ECM Parts
The Powertrain Control Module abbreviated as PCM is located in the engine area. PCM is also described as JTEC which is Jeep/Truck Engine Controller. It is just 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, power over speed, air conditioning converter, 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 functions are regulated through different system components with the aid 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 helps in adjusting combustion timing which is structured after the inputs it receives from the detectors which react to engine rpm, engine coolant temp, manifold absolute pressure, tranny gear selection (automatic transmission), throttle position, brake switch and the speed of vehicle. PCM helps in adjusting the idle velocity which is founded on inputs, which it gets from the sensors.
