DTC P0112 Intake Air Temperature Sensor (ATS) Circuit Low Voltage

DESCRIPTION

The Intake Air Temperature (ATS) sensor is in the MAF sensor. The ATS sensor is a variable resistor whose resistance changes as the temperature of the air flowing through the air intake changes. ECU uses the ATS sensor input to adjust fuel injector pulse width. When the temperature sensed is cold, the ECU enriches fuel mixture by increasing injector pulse width as the air warms, the injector pulse width time is shortened.
