SOURCE: location of the bank 1 sensor 2 O2 sensor on a 2001 ford escape
B1 means the sensor is located on the same bank of the engine that has the #1 cylinder. B2 is located on the opposite bank.
S1 means the sensor is located BEFORE the catalytic converter
S2 means the sensor is located AFTER the catalytic converter
You didn't say which engine you have, so I've included the diagrams of both 4 cyl and 6 cyl so you can see the banks
SOURCE: IAT sensor
The IAT (Intake Air Temperture) is the sensor that measures the temp of the incoming air to the engine, it is either in the rubber hose to the engine from the air filter housing, or on the air filter housing itself, it is small and round with 2 wires going to it, many times it is left unplugged during routine maintenance.
SOURCE: Need to find where the IAT sensor is located?
it is the air Intake Temperature Sensor located at the air cleaner housing.
SOURCE: i cant find the IAT sensor on my 98 ford explorer XLT v 6 SOHC
Try “autozone.com” or your local library for diagrams and step by step instructions.
