How much does it cost to replace a common crankshaft position sensor?

by Daysyore Auto Parts 13 Apr 2023 0 Comments

The crankshaft position sensor, as its name implies, plays an important role in monitoring the change of crankshaft position. If it breaks, the car's ECU would have no idea about what was happening to the crankshaft inside the engine in real-time. Due to its importance, most people are very concerned about the cost of replacing the crankshaft position sensor.

This article will tell you the answer and give you details about the crankshaft position sensor and the parts associated with it. Let's look down together!

What role does the crankshaft position sensor play in the engine?

The crankshaft position sensor is a sentinel in the engine system, which transmits important information about the crankshaft motion state. The information being transmitted is relevant to the normal operation of the whole engine.

Crankshaft position sensor

A crankshaft position sensor is an electronic device used in gasoline and diesel internal combustion engines to monitor the position or speed of the crankshaft. This information is used by the engine management system to control the fuel injection or ignition system timing and other engine parameters.

The sensor is commonly a magnetic or optical sensor and mainly detects the rotation of a gear or disk mounted on the crankshaft. As the crankshaft rotates, the toothed wheel or disc passes the sensor, which sends signals to the ECM or PCM indicating the position and speed of the crankshaft. This information is then used by the ECM or PCM to determine the correct timing of engine ignition and fuel injection systems. This will help ensure that the engine runs efficiently and smoothly and reduce emissions.

If the crankshaft position sensor fails or fails, it can cause a wide variety of engine performance issues, including poor acceleration, stall, or even a complete failure to start. Therefore, once the sensor is damaged, it is recommended to find a professional auto repair shop or professional repair technician to check and replace it.

A crankshaft is a mechanical component used in a piston engine to convert reciprocating motion into rotational motion. A crankshaft is a rotating shaft containing one or more crankshaft pins driven by a piston through a connecting rod. Crankshaft pins are also known as connecting rod bearing journals, they rotate inside the "big end" of the connecting rod. Most crankshafts are located inside the engine. They are made of steel or cast iron using forging, casting, or machining processes.

Main Bearings

Main bearings in engine usually refer to crankshaft main bearings.
In a piston engine, the main bearing is the bearing used to hold the crankshaft and rotate it in the engine compartment.

The main bearing is usually a sliding bearing or journal bearing, which is fixed by the body and bearing cover. Regarding its running position, the main bearing is installed in the crankcase, which is generally composed of two parts: upper and lower. The number of main bearings per engine varies from engine to engine and is usually related to the force generated when the engine is running.
