How to Clean the Engine RPM Sensors

Model: (Various brands) Various
Part: Crankshaft position sensor

Today, with the help of this short video tutorial, you will learn how to clean the engine RPM sensors of your vehicle easily and economically. As we know, if the sensors are dirty, they can cause a loss of engine power, unnecessarily increasing RPM and leading to higher fuel consumption. To clean the sensors, you will need a screwdriver and brake cleaner spray. The brake cleaner, being alcohol-based, will allow you to clean your sensors more effectively than oily sprays. Start by cleaning the Deby M sensor, located near the air filter. Spray it and let it sit. Proceed in the same manner with all other sensors. Be careful, as some may need to be removed before cleaning.
