Fix electrical terminal corrosion

Today’s computerized vehicles send fairly low voltage to the sensors. Any small amount of electrical corrosion can really screw up the signal back to the computer. Before you replace a sensor, pull off the electrical connector and check for corrosion (green stuff). If you find it, clean it with electrical contact cleaner. Then apply a coating of stabilant 22 contact conditioner (or deoxit). That will prevent further corrosion. If you don’t apply a conditioner, the corrosion will return.
