Replacing The Intake Air Temperature Sensor To Fix P0113 Code In A Chrysler 300

By Nick Marchenko, PhD

If you're the proud owner of a 2015 Chrysler 300 and have been perturbed by the glow of the check engine light illuminating your dashboard, accompanied by the mysterious P0113 code, you're in the right place. Today, we'll embark on an automotive journey to replace the intake air temperature sensor, potentially solving your conundrum.

Understanding the P0113 Code

The P0113 code signifies a high voltage issue in the intake air temperature sensor circuit. This sensor measures the temperature of the air entering your engine. Accurate readings from this sensor are crucial for your engine's computer to adjust the air-fuel mixture properly. A fault here can lead to various engine issues, including decreased fuel efficiency and increased emissions.

Locating the Sensor

In the case of our illustrious Chrysler 300, which boasts a 3.6L Pentastar motor and revels in its rear-wheel-drive configuration, some components sit in less traditional locales due to its longitudinal engine setup. Before diving in, ensure your vehicle is in the "Run" position without the engine running, as starting this procedure requires interaction with the vehicle's OBD2 port for diagnostic confirmation.

Our target, the intake air temperature sensor, is nestled within the air intake assembly. This crucial component does not reside with the mass airflow sensor, as one might expect, but instead enjoys solitude along the intake tube.

Step-by-Step Replacement

1. Begin by gently removing the cover over the air intake, thus exposing the path to our elusive sensor.
2. Trace the intake tube until you spot the sensor. Disconnect its connector by squeezing and pulling – a simple, yet satisfying task.
3. With the sensor in your sights, remove the intake system to gain better access. A couple of screws, an 8 mm wrench in hand, and voila!
4. Extract the sensor with a quarter turn, a move reminiscent of opening a treasure chest, albeit less dramatic.
5. Introduce the new sensor into its home, securing it with a clockwise twist. Reassemble the intake system and reconnect all hoses and electrical connectors, ensuring everything is snug and secure.

Final Checks and Code Clearance

Before declaring victory, inspect the intake system for any cracks or leaks. Such imperfections could sabotage our efforts by affecting the sensor's readings.

Reconnect your scanner and clear the P0113 code. After a ceremonious engine start (ensuring it's not running for the code clearing process), verify that the code has indeed been banished to the annals of history.

However, our journey might not end here. It's prudent to monitor the situation, running the vehicle a few times to ensure the specter of the check engine light does not return. Persistent issues might hint at deeper mysteries, like a gaping breach in the air intake system or another sensor's rebellion.
