P244C OBD2: Exhaust Temperature Too Low For Particulate Filter Regeneration

The P244C code is an OBD-II trouble code that indicates the exhaust temperature is too low for the diesel particulate filter (DPF) regeneration process to occur. This code is primarily associated with diesel engines that utilize Diesel Exhaust Fluid (DEF) to manage emissions.

What Does the P244C Code Mean?

The P244C code signifies that the exhaust temperature is not reaching the necessary levels for the DPF to effectively burn off the trapped particulate matter. This is crucial for maintaining optimal engine performance and reducing harmful emissions.

What Causes the P244C Code?

Several factors can trigger the P244C code, including:

  • DEF injector failure
  • Exhaust Gas Temperature (EGT) sensor failure
  • Exhaust leaks
  • Restricted diesel particulate filter

What Are the Symptoms of the P244C Code?

When the P244C code is present, you may experience symptoms such as:

  • Decreased engine performance
  • Increased emissions
  • Warning lights on the dashboard

How Serious Is the P244C Code?

The P244C code is classified as urgent. If left unaddressed, it can lead to significant engine damage and pose a risk to driver and passenger safety. Immediate action is recommended to prevent further complications.

How to Diagnose the P244C Code

To properly diagnose the P244C code, a mechanic will typically follow these steps:

  1. Use an OBD-II scanner to confirm the P244C code and check for any additional codes.
  2. Inspect the exhaust system for leaks or damage.
  3. Test the DEF injector and EGT sensor for proper functionality.
  4. Examine the DPF for restrictions or blockages.

Common Repairs for the P244C Code

Common repairs associated with the P244C code may include:

  • Replacing a faulty DEF injector
  • Replacing a malfunctioning EGT sensor
  • Repairing any exhaust leaks
  • Cleaning or replacing a restricted diesel particulate filter

How Much Does It Cost to Fix the P244C Code?

The cost to repair the P244C code can vary widely depending on the specific issue and make/model of the vehicle. On average, repairs can range from $200 to $1200, including parts and labor.

Can I Fix the P244C Code Myself?

While some DIY enthusiasts may tackle repairs related to the P244C code, it is essential to accurately diagnose the problem first. If you are not experienced with automotive repairs, it is advisable to seek professional assistance to avoid unnecessary expenses and ensure proper resolution.
