DTC P0112 & DTC P0113: Notes

Code Definition

DTC P0112: Intake Air Temperature Sensor Circuit Low Voltage
DTC P0113: Intake Air Temperature Sensor Circuit High Voltage

NOTE: Intake Air Temperature (IAT) sensor is built into Mass Air Flow (MAF) sensor and they share same harness connector.

NOTE: Before performing any diagnostic test, refer toWARNINGS, CAUTIONS and NOTES in DIAGNOSTIC TESTS .

NOTE: Testing individual components does not isolate shorts or opens. Perform all voltage tests using a Digital Volt-Ohmmeter Meter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in test procedure. Use ohmmeter to isolate wiring harness shorts or opens.
