TOYOTA 8961532040 Knock Sensor

This is a genuine TOYOTA knock sensor, part number 8961532040, with the original part number 89615-32030. It is manufactured in Japan, ensuring high quality and reliability. The knock sensor plays a crucial role in modern engine management systems. It detects abnormal vibrations or 'knocking' within the engine cylinders, which can occur when the fuel-air mixture ignites prematurely or unevenly. Upon detection, the sensor sends a signal to the engine control unit (ECU). The ECU then adjusts ignition timing and fuel injection to prevent further knocking. This process is vital for protecting the engine from potential damage, such as piston or connecting rod failure, and for maintaining optimal performance, fuel efficiency, and smooth operation. Replacing a faulty knock sensor with this genuine TOYOTA part will restore your vehicle's engine health and prevent costly repairs down the line.
