P0113

Intake Air Temperature Circuit High Input

Lowsensor

Overview

The P0113 diagnostic trouble code means the PCM has identified a intake air temperature circuit high input problem. This code indicates that a sensor or its circuit is not providing expected readings to the engine management system. Faulty sensor data can cause the PCM to make incorrect adjustments, affecting engine performance.

Symptoms

  • Hard starting in certain conditions
  • Intermittent stalling
  • Incorrect gauge readings
  • Reduced engine performance

Common Causes

  • Physical damage to sensor
  • Poor ground connection for sensor
  • Sensor contamination or buildup
  • Wiring issues (open, short, or high resistance)

Diagnosis Steps

  1. 1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
  2. 2Locate the specific sensor referenced by the code
  3. 3Inspect the sensor connector for corrosion, damage, or loose pins
  4. 4Test the sensor output using a multimeter or scan tool live data
  5. 5Check the wiring between the sensor and the PCM for opens or shorts
