Sensors in your 2005 Dodge Ram 1500 are used to control, and process the pressure of oil, temperature, emission, coolant levels and more. When a sensor is malfunctioning, your levels will be completely off and your 2005 Dodge Ram 1500 will not be running at optimal performance. In many cases, a faulty sensor can be the reason for a check engline light.
Here are examples of several popular sensors and their key functions. Camshaft Position (CMP) & Crankshaft Position (CKP) – These sensors help provide signals to the PCM/ECM. The PCM/ECM needs to know the position of the valves in relation to the pistons and the rotational speed of the crankshaft, Once the signal is provided, proper fuel will be injected into the spark plugs.
Knock Sensor (KS) - The Knock Sensor controls your ignition timing by sending a voltage signal to the computer if vibration caused by detonation is detected. This enables the computer to retard spark advance and prevent engine damage.
The Throttle Position Sensor (TPS) – TPS signals the computer the position of the throttle shaft, indicating how fast you want to go. The PCM/ECM uses this information along with the Mass Air Flow (MAF) sensor signal, to calculate engine load, with increased load requiring more fuel.
This is just several popular sensors which are essential in your vehicles function but there are many more. Be sure to check through all categories to see our full catalog.
