DTC P0113 Acura

Intake Air Temperature (IAT) Sensor Circuit High Voltage

Intake Air Temperature (IAT) Sensor Circuit High Voltage

Description

The IAT sensor resistance varies depending on temperature. The output voltage and the sensor resistance increase as the intake air temperature decreases. Conversely, the output voltage and the sensor resistance decrease as the intake air temperature increases. If the IAT sensor output voltage is excessively high, the Powertrain Control Module (PCM) detects a malfunction and a DTC is stored. The execution time is continuous and the duration time is 2 seconds or more. P0112 is not active. The IAT sensor output voltage is 4.92 V or more for at least 2 seconds. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.

Cause and Solution

Poor connections or loose terminals at the MAF sensor IAT sensor and the PCM
Open in the wire between the PCM and the MAF sensor IAT sensor
Open in the wire between the PCM and the MAF sensor IAT sensor
Faulty MAF sensor IAT sensor
PCM may need to be updated with the latest software
