What Does a Performance Mass Air Flow Sensor Do? Your mass air flow sensor or “MAF” detects the volume of air as it enters your engine by heating up a thin wire or resistor.The computer in your car then measures electrical resistance through the MAF as the air flowing through the sensor cools its components down.our mass air flow sensor or “MAF” detects the volume of air as it enters your engine by heating up a thin wire or resistor.

Knock Sensor Without a properly working knock sensor your car's engine cannot process fuel without knocking, pinging, and rattling its way down the street. Turn off your car when the knock sensor is dead and you are likely to witness your car shaking, gasping, and rattling for several seconds after you turn off the ignition.

- Q) What does a knock sensor do? A) A knock sensor is a specially designed listening device for car engines. It listens for engine knock, or detonation (pinging). Detonation can be very bad for an engine and is the result of the fuel/air mixture exploding too quickly instead of burning evenly and rapidly.

What Does a Carbon Monoxide Detector Do and How Does it Work? Different types of alarms are triggered by different types of sensors. 1  Biomimetic sensor: A gel changes color when it absorbs carbon monoxide, and this color change triggers the alarm. 2  Metal oxide semiconductor: When the silica chip's circuitry detects carbon monoxide, it lowers the electrical resistance, and this change triggers the alarm.

Toyota Knock Sensor So, there are some things to consider when replacing the knock sensor. Doesn’t matter if you perform this yourself or have a repair shop do the repair. These things should still be considered. When replacing the knock sensors the upper and lower intake manifold has to be removed and that alone is a lot of work.

- When you start a car/truck, the knock sensor allows the PCM to adjust timing by sensing pinging or knock immediately. This allows the engine to get the most power out of the fuel you happen to be running.If the knock sensor malfunctions, the PCM just runs a default timing routine (like running 87).etonation can be caused by several factors; low octane fuel, too much spark advance, or a lean fuel mixture. The knock sensor will send a signal back to the PCM (power control module) to lower advance and/or enrichen the fuel mixture.

How Does an Alarm Motion Sensor Work? Active motion sensors (also called radar-based motion detectors) send out ultrasonic sound waves – the same waves used in pregnancy ultrasounds – and these waves reflect back to the sensor. This pattern continues until it’s disrupted by an interference of some sort (e.g. a person walking past).
