Let’s explore how this sensor works, why it matters, and what makes it an ideal solution for 4×4 owners and diesel vehicle enthusiasts.

What Is an Exhaust Gas Temperature Sensor?

An Exhaust Gas Temperature Sensor (EGT Sensor) monitors the temperature of the exhaust gases exiting your engine. This data is critical for:

• Preventing overheating of engine components

• Optimizing fuel injection timing

• Controlling turbocharger efficiency

• Managing Diesel Particulate Filter (DPF) regeneration

• Reducing emissions and ensuring compliance

The Aftermarket Exhaust Gas Temperature Sensor 68193645AB measures these values and transmits them to the engine control unit (ECU), allowing for real-time adjustments to protect the engine and optimize combustion efficiency.

Why Choose the Aftermarket Exhaust Gas Temperature Sensor 68193645AB?

The 68193645AB sensor is designed as a direct-fit aftermarket replacement part. It ensures precise readings and integrates seamlessly into your vehicle’s existing electronic systems. Here’s why this sensor is a smart investment:

• OEM-Compatible Performance – Delivers factory-grade functionality at a more affordable price.

• Direct Plug-and-Play Fitment – No modifications required. Simply install and go.

• Wide Vehicle Compatibility – Works with a range of diesel vehicles including Dodge Ram 2500, 3500, Jeep Grand Cherokee, and more.

Compatibility & Applications

The Aftermarket Exhaust Gas Temperature Sensor 68193645AB is commonly used in:

• Dodge Ram 2500/3500 with 6.7L Cummins Diesel Engines

• Jeep Grand Cherokee (EcoDiesel Models)

• Chrysler and RAM Trucks

• Other heavy-duty diesel vehicles using the Cummins or EcoDiesel platform

Always confirm compatibility using your vehicle’s VIN or refer to the service manual before purchasing.

Technical Specifications

• Part Number: 68193645AB

• Sensor Type: Thermocouple

• Mounting Style: Threaded bolt-in

• Connector Type: Factory-style plug (OEM fit)

• Wire Length: Standard (OEM-matched)

How It Works

Once the engine runs, exhaust gases flow from the combustion chamber into the exhaust system. These gases can exceed 800°C during heavy acceleration or towing.

The Aftermarket Exhaust Gas Temperature Sensor 68193645AB detects this heat and sends signals to the ECU. This data allows the vehicle’s systems to:

• Adjust the fuel-to-air mixture

• Activate cooling systems

• Initiate DPF regeneration cycles

• Prevent turbo or catalytic converter damage

In essence, the sensor is your vehicle’s early-warning system against thermal stress.

Installation Tips

Installation is straightforward, but following proper steps can ensure accurate performance:

1. Locate the faulty sensor – Often found in the exhaust manifold, DPF, or near the turbocharger.

2. Disconnect the battery – Always disconnect the negative terminal for safety.

3. Remove the old sensor – Use a wrench or sensor socket.

4. Install the new sensor – Ensure it’s tightened securely, and plug in the connector.

5. Reconnect battery and clear any fault codes using a compatible OBD-II scanner.

If you’re not confident with DIY installation, consult a certified mechanic.

Signs You Need a New Exhaust Gas Temperature Sensor

Over time, sensors can degrade due to high heat and carbon buildup. Common signs of failure include:

• Check Engine Light (CEL)

• Poor fuel economy

• Black smoke from exhaust

• Turbo lag

• Failed emissions test

• DPF regeneration failure

Replacing a faulty sensor with the Aftermarket Exhaust Gas Temperature Sensor 68193645AB restores your vehicle’s performance and helps avoid costly repairs down the line.
