Intake Air Temperature Sensor (IATS) is included inside Barometric Pressure Sensor (BPS) and detects the intake air temperature.
To calculate precise air quantity, correction of the air
temperature is needed because air density varies according to the
temperature. So the ECM uses not only BPS signal but also IATS signal.
This sensor has a Negative Temperature Coefficient (NTC) thermistor and
it''s resistance changes in reverse proportion to the temperature.
Inspection
1.
Connect the GDS on the Data Link Connector (DLC).
2.
Measure the output voltage of the BPS at idle and IG ON.

Description
A spark plug is a device for delivering electric current from
an ignition system to the combustion chamber of a spark-ignition engine
to ignite the compressed fuel/air mixture therein by means of an
electric spark, while containing combustion pressure within the engine. A
