This summary uses the existing diagnostic information shown in full below.
Your car has a special filter that helps clean the air. It needs to get hot to work properly, but right now it's not getting hot enough on one side of the engine.
This code indicates that the temperature in the exhaust system is not reaching the required level for the diesel particulate filter (DPF) to regenerate on Bank 2.
The diesel particulate filter (DPF) is designed to capture and store exhaust soot in order to reduce emissions. For the DPF to clean itself, or regenerate, the exhaust temperature must be sufficiently high. Code P244E is triggered when the exhaust temperature on Bank 2 is too low to allow this regeneration process to occur.
• Check engine light is on
• Reduced engine performance
• Increased fuel consumption
• Faulty exhaust temperature sensor
• Exhaust leaks
• Issues with the fuel injection system
DPF: Diesel Particulate Filter
Bank 2: The side of the engine opposite to Bank 1, typically the side without cylinder 1
• Check for any exhaust leaks in Bank 2
• Test the exhaust temperature sensor for proper operation
• Inspect the fuel injection system for issues
• Replace faulty exhaust temperature sensor
• Repair any exhaust leaks
• Service the fuel injection system
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Ford F-250
• Chevrolet Silverado
• Dodge Ram 2500
• Regularly inspect the exhaust system
• Ensure timely maintenance of the fuel system
• Avoid excessive idling
Engine Performance
• Avoid short trips that do not allow the engine to reach optimal temperature
• Regularly drive the vehicle at highway speeds to facilitate DPF regeneration
Check with your vehicle manufacturer for warranty coverage on emissions-related components.
This code has become more common with the increased use of diesel particulate filters in modern diesel engines.
Moderate – Addressing this issue is important to prevent damage to the DPF and maintain vehicle performance.
Ignoring this code can lead to increased emissions and potential damage to the vehicle's exhaust system.
• Vehicle at operating temperature
• Highway driving conditions
The exhaust temperature sensor is located in the exhaust system on the side of the engine labeled as Bank 2.
Q: What happens if I ignore this code?
A: Ignoring this code can lead to a clogged DPF, reduced engine performance, and increased emissions.
Q: Can I drive with this code?
A: While you can drive with this code, it is advisable to address it soon to prevent further issues.
Budget · Enhanced code reader
A wired color-screen reader with readiness hotkeys, live data, code definitions, and data logging.
Good for emissions-related codes because it exposes readiness monitors and live powertrain data.

Specialty · Smoke machine
Helpful for finding EVAP and vacuum leaks that are hard to see with visual inspection alone.
Helpful for tracking down EVAP and vacuum leaks that can trigger emissions faults.

Specialty · O2 sensor socket
Helpful when the code points toward exhaust or oxygen-sensor work and space is tight.
Useful when the diagnosis points toward oxygen-sensor removal or replacement.
