How to Fix the P0113 Error Code in Your Chrysler 300

If you own a Chrysler 300 and have encountered the P0113 error code, you're likely dealing with an issue related to the Intake Air Temperature (IAT) sensor. This sensor measures the temperature of the air entering the engine, which is crucial for proper air-fuel mixture. The P0113 code indicates that the IAT sensor is sending a higher voltage than expected, suggesting that it's reading an abnormally high air temperature.

Understanding the P0113 Code

The P0113 code is a generic powertrain code related to the engine and transmission, including the intake air temperature sensor. Here's what it specifically means for your Chrysler 300:

  • P0113: Intake Air Temperature Sensor 1 Circuit High Input

This error can lead to various symptoms, including:

  • Check engine light is on
  • Poor fuel economy
  • Irregular engine behavior like rough idling or difficulty starting

Steps to Diagnose and Fix the P0113 Error

Step 1: Inspect the IAT Sensor

  1. Locate the IAT Sensor: It's typically found in the air intake duct or integrated with the mass air flow (MAF) sensor.
  2. Check for Visible Damage: Look for any signs of damage or corrosion on the sensor and its connector.
  3. Ensure Tight Connections: Loose connections can cause incorrect readings.

Step 2: Test the IAT Sensor

  1. Use a Multimeter: Set it to the resistance mode and check the resistance of the sensor. Compare it with the standard values (refer to your car’s manual).
  2. Check Voltage: With the engine running, measure the voltage. It should not be excessively high when the engine is cold.

Step 3: Replace the IAT Sensor if Necessary

If the sensor is faulty, replacing it is straightforward:

  1. Disconnect the Battery: Ensure safety by disconnecting the battery.
  2. Remove the Old Sensor: Unscrew or unclip the old sensor from its mount.
  3. Install the New Sensor: Place the new sensor in the same position and reconnect it.
  4. Reconnect the Battery and Test: After installation, reconnect the battery and start the engine to check if the error code returns.

Step 4: Check for Other Potential Issues

If replacing the IAT sensor doesn’t resolve the P0113 code, consider these areas:

  • Air Leaks: Check for any leaks in the air intake system.
  • Wiring Issues: Inspect the wiring harness for damage or shorts.
  • ECU Problems: In rare cases, the issue might be with the car’s computer system.
