P0113 – Intake Air Temperature (IAT) Circuit High Input

P0113 – Intake Air Temperature (IAT) Circuit High Input

Description

Indicates the sensor
signal is greater than Self-Test maximum. The IAT sensor maximum is 4.6 volts or -50°C (-46°F).

●● Open circuit in harness
● Sensor signal short to power
● Damaged sensor
● Improper harness connection
● Damaged PCM

Diagnostic Aides

 ■ Using signal simulation,
disconnect sensor and simulate 1.0V on sensor signal circuit. Simulated 1.0V signal and scan PID voltage value should be similar. If voltage is similar check sensor, if voltage is not similar check related circuit and PCM.
