P0113 — Intake Air Temperature Circuit High Input Bank 1
Category: Powertrain Severity: Low
Updated:
DTC code P0113 means: Intake Air Temperature Circuit High Input Bank 1. It falls under the "Powertrain" category, with an estimated severity of Low. Common causes include faulty IAT sensor, open/short in IAT wiring and faulty ECM; it's worth confirming the diagnosis before replacing parts.
Possible causes
- Faulty IAT sensor
- Open/short in IAT wiring
- Faulty ECM
Symptoms
- Loss of power when accelerating
- Unstable idle
- Higher fuel consumption
- Jerking while driving
How to diagnose it step by step
- Read IAT cold: -40 means an open circuit.
- Check the connector (often on the MAF).
- Jumper signal to ground: if it jumps to high temperature, the sensor is open.
- Replace the sensor.
How to fix it
Clean or replace the MAF/MAP sensor and check for intake leaks.
Estimated repair cost
$15–70 (up to $300 if part of the MAF).
