When you say that I should spray the contacts, are you referring to spraying the electrical connection that I disconnect in order to clean or replace the sensors (eg. MAF sensor)?
Not exactly...
The Mass Air Flow (MAF) sensor sits in the air intake between the air filter and the throttle body. It looks like a piece of screen with very fine wires criss-crossing across the opening. These wires vibrate to measure the volume of air entering the engine, and the Powertrain Control Module (PCM) uses this info to tell the fuel injectors how much fuel to add.
A typical sensor looks like this:
The wires can get dirty and send a bad reading to the PCM. The wires are VERY fragile so you need to be careful removing teh sensor and use ONLY cleaning fluid specified for MAF.
This is the correct cleaner:
Here is a
You Tube Video on how to remove and clean a MAF. Your set up will be slightly different, but you'll be able to identify the parts and remove them after you watch the video.
