The crankshaft sensor is one of the most important informants of the engine control unit. It detects the speed and position of the crankshaft and supplies this information to the engine control unit in the form of an electrical signal. So, a buyer of Mitsubishi Shogun elegance for sale should know that, how the crankshaft sensors work and the procedures to be adopted during the check to prevent damage.
The Purpose Of The Crankshaft
The purpose of the crankshaft sensors is to determine the speed and position of the crankshaft. Most often they are installed near the flywheel on the ring gear. There are two models: inductive sensors and Hall sensors. Before carrying out a check on the crankshaft sensor, it must be established which type of sensor it is. The rotation of the ring gear causes changes in the magnetic field. These generate different voltage signals in the crankshaft sensor which are transmitted to the control unit. From the received signals, the control unit calculates the speed and position of the crankshaft to obtain basic data important for ignition injection and adjustment.
Direct control of the crankshaft sensor can be difficult if the exact sensor model is not known. Before checking, it must be clarified whether it is an inductive sensor or Hall. Both variants are not always distinguishable from a visual point of view. With a three-pin connector, it is not possible to determine exactly the corresponding model. In this regard, the manufacturer's specific instructions and the spare parts catalog information contribute to clarification.
The Crankshaft Position
The crankshaft position sensor transmits the main input signal to the control unit. Unlike other sensors, in the event of a fault, the control unit cannot calculate a predefined value and keep the motor running. In the absence of the specific signal provided by the crankshaft sensor, the control unit is not able to keep the engine running, with consequent vehicle failure. Here, it would like to add that, the crank pin is made of steel (like the two half-shafts) and is made in such a way as to allow the rollers of the connecting rod bearing to work directly on it (in the past for a long time the trees in which the track of rolling for the rollers was obtained instead in a ring inserted by pressure on the pin). It is therefore worked with great dimensional and geometric precision and is endowed with an excellent surface finish and a high hardness, obtained by cementation followed by tempering.
The Consequences & The Vehicle
In the event of a failure of the camshaft sensor, the consequences are less important, but the vehicle may have difficulty starting. Furthermore, if the motor is equipped with variable valve timing, there will also be repercussions in this regard, since the signal of the camshaft sensor is used to monitor this function. The engine will continue to operate, but with reduced power and performance. The sensors do not have mandatory replacement intervals. Water in the connector or sensor, broken wires and age are factors that can contribute to the failure of the crankshaft and camshaft sensors. To prevent the failure of these parts, it is recommended to replace them periodically during the life of the vehicle to protect the resales Mitsubishi shogun elegance price.
