As a proud Range Rover owner, I have experienced the joys and struggles that come with owning one of these luxurious vehicles.

And let’s be honest, with Range Rover’s well-known inclination towards experiencing reliability issues, we all need to be prepared for some occasional hiccups along the way.

One of the recent issues I faced was the Defective Intake Air Temperature Sensor P0113, a common problem amongst all Range Rover models.

What models are affected?

• Land Rover Defender
• Range Rover Discovery
• Range Rover Evoque
• Range Rover Sport
• Range Rover Velar
• Range Rover Vogue

Signs and symptoms

The Intake Air Temperature (IAT) sensor is an important component of the engine system that monitors the temperature of the air entering the engine.

When the IAT sensor malfunctions, it sends incorrect readings to the vehicle’s computer, which can cause a variety of problems with the engine’s operation.

Here are some common signs of a Defective Intake Air Temperature Sensor P0113:

• Check Engine Light: The Check Engine Light will illuminate when the IAT sensor is malfunctioning.
• Engine Running Poorly: When the IAT sensor sends incorrect readings to the computer, it can cause the engine to run too rich or too lean.
• Decreased Fuel Efficiency: Issues with the IAT sensor can cause the engine to consume more fuel than it should, causing a decrease in fuel efficiency.
• Issues Starting the Vehicle: In some cases, a malfunctioning IAT sensor can make it difficult to start the vehicle.

If you notice any of these signs, it’s best to take your vehicle to a trusted mechanic to diagnose the issue.

List of possible OBD codes

When a Range Rover experiences a Defective Intake Air Temperature Sensor P0113, it can cause the vehicle’s On-Board Diagnostics (OBD) system to register a variety of codes.

Here are some of the most common OBD codes related to the IAT sensor:

• P0113- Intake Air Temperature Circuit High Input
• P0112- Intake Air Temperature Circuit Low Input
• P0111- Intake Air Temperature Circuit Range/Performance Problem

If you receive any of these codes, it’s important to address the issue immediately.

Common causes

There are several common causes of a Defective Intake Air Temperature Sensor P0113 in Range Rover models. Here are some that we’ve seen during our years of experience working with Range Rovers:

• Faulty Sensor: The IAT sensor can become damaged over time, causing it to malfunction.
• Short Circuit: Damage or corrosion to the wiring in the IAT sensor circuit can cause a short circuit.
• Loose Connections: Loose connections can cause the IAT sensor to malfunction and send incorrect readings to the vehicle’s computer.
• Faulty Computer: A faulty or damaged vehicle computer can cause issues with the IAT sensor readings.

Can it be fixed without a mechanic?

If you’re an experienced DIYer, it’s possible to fix a Defective Intake Air Temperature Sensor P0113 yourself.

However, it’s always recommended to take your vehicle to a professional mechanic to ensure the issue is accurately diagnosed and repaired.

Parts you’ll need to fix it

To repair a Defective Intake Air Temperature Sensor P0113, you will need to purchase a replacement IAT sensor.

Tools you’ll need to fix it

Here are the tools you’ll need to fix a Defective Intake Air Temperature Sensor P0113:

• Pliers
• Screwdrivers
• Socket Set
• Wrench Set

How to fix it

Here is a step-by-step guide to fix a Defective Intake Air Temperature Sensor P0113:

1. Turn off the engine and disconnect the negative battery cable.
2. Locate the IAT sensor. It is typically near the air filter box or the air intake manifold.
3. Disconnect the electrical connection to the IAT sensor by pressing the tab and pulling the connector apart.
4. Using pliers, remove the IAT sensor by twisting it counterclockwise.
5. Install the new IAT sensor by turning it clockwise until it clicks into place.
6. Reconnect the electrical connection to the IAT sensor by pressing the tab and plugging the connector back in.
7. Reconnect the negative battery cable and start the engine to ensure the problem is resolved.

Potential alternative causes

There are other issues that can cause similar symptoms to a Defective Intake Air Temperature Sensor P0113. Here are some other potential causes you should be aware of:

• Clogged Air Filter: If your air filter is clogged, it can cause issues with the engine’s air intake system and send false readings to the IAT sensor.
• Poor Electrical Connections: Loose or corroded electrical connections throughout the engine system can cause issues with the IAT sensor’s readings.
• Worn Spark Plugs: Worn spark plugs can cause the engine to run too lean or too rich, leading to similar symptoms as a malfunctioning IAT sensor.
