Mass Air Flow Sensor

The Bosch engine coolant temperature sensor is a vital component for monitoring your vehicle's operating temperature. This sensor communicates coolant temperature data to the ECU, which uses it for critical functions including air-fuel mixture, ignition timing, and cooling fan control. A malfunctioning sensor can lead to incorrect temperature readings, impacting engine performance and potentially causing issues like rough idling, poor fuel economy, or even engine overheating warnings. This sensor features a M12x1.5 male thread, a 19 mm wrench size, and an installation torque specification of 25 Nm. It has a weight of 29g without the wire and uses a 2 Prong FI Type Connector with a Blue Insulator. It is made in the Czech Republic and is considered Genuine quality.
