MAF Sensor — What is a MAF sensor?
What is a MAF sensor and how does it fail? Mass Airflow Sensor — MAF A mass airflow sensor (MAF) attempts to measure the density of the air coming into the engine. A mass airflow sensor sensor measures air density using either a hot wire or a hot plate and a separate incoming air temperature sensor. The wire or sensor is first heated to a set temperature. Air flowing past the hot wire or plate cools it. The mass airflow sensor then applies more current to reheat the wire or … Read More
The benefits of using back probe pins and probes
Use back probe pins to diagnose electrical, sensor, and computer issues When you’re checking live voltage readings on sensors, you have to connect to the wires while it’s connected. Some techs stick a pin through the wire. That works, but it can create problems later on if you don’t properly seal the insulation when you’re done. The best and most professional way is to use back probe pins since they don’t damage the insulation. I’ll show you the pros and cons of wire piercing probes, back pin probes, and spoon … Read More
Clean a MAF sensor — step by step guide for DIYers
How to Clean a MAF Sensor And Get Quicker Starts Carmakers say you can’t clean a MAF sensor you must replace it. They’re wrong. You can clean it, but it’s very delicate and must be done with care. I’ll show you the step-by-step process to clean yours. But first, let’s go over the basics: What does a MAF sensor do and how does it do it? A MAF sensor calculates the volume and mass of the air entering the engine so the ECM can calculate the right amount of fuel … Read More
