Video tutorial

This video shows where the crankshaft RPM sensor is located in the Smart ForTwo, useful in case you need to replace it. As shown, the sensor is positioned in the upper left area of the engine, but to access it, you will need to remove the intercooler, the EGR valve, and the ECU, tasks that can take quite some time.

Replacing the sensor is very simple; just disconnect the power connector, undo the two securing bolts, and follow the reverse procedure.

Ensure you work with the engine completely cold.
