Code P244C Cadillac Description
The P244C diagnostic trouble code (DTC) for Cadillac vehicles indicates that the catalyst temperature is too low during the regeneration process. This code typically pertains to vehicles equipped with a diesel engine and a diesel particulate filter (DPF) system. During normal operation, the DPF collects and stores soot particles from the exhaust gases, which are then burned off during regeneration to prevent a build-up that could restrict exhaust flow and reduce engine performance.
Common Causes of P244C Cadillac
- Malfunctioning DOC or DPF temperature sensor
- Faulty regeneration control module
- Malfunctioning EGT sensors
- Clogged DPF
- Poor quality diesel fuel
Symptoms of P244C Cadillac
- Check engine light illuminated
- Reduced engine performance
- Increased fuel consumption
- Exhaust smoke or odor
- Reduced regeneration intervals
How to Fix P244C Cadillac
- Use a diagnostic scan tool to retrieve the trouble code and determine the exact cause of the issue.
- Inspect the DOC and DPF temperature sensors for proper operation and replace if necessary.
- Check the regeneration control module and EGT sensors for faults and replace as needed.
- Perform a forced regeneration of the DPF to clear out any accumulated soot and verify proper operation.
- Test drive the vehicle to ensure that the P244C trouble code does not return and that the catalyst temperature is within the specified range during regeneration.
Cost to Fix P244C Cadillac
The typical repair costs for addressing a P244C trouble code can vary depending on the specific cause of the issue and the labor rates at the auto repair shop. In general, the replacement of sensors or modules involved in the regeneration system can range from $200 to $500, including parts and labor. Additionally, a forced regeneration service may cost around $100 to $200. It's recommended to inquire with local auto repair shops for accurate pricing based on the vehicle's make and model, as well as any additional diagnostics or repairs that may be required.

Frequently Asked Questions about P244C Cadillac Code
1. What does OBDII code P244C mean on a Cadillac?
P244C indicates that the catalyst temperature is too low during the regeneration process of the diesel particulate filter (DPF), which may prevent proper soot burn-off.
2. What are the common symptoms of code P244C in a Cadillac?
Symptoms include increased exhaust emissions, reduced fuel efficiency, illuminated check engine light, and possible DPF regeneration failure.
3. What causes the P244C code to appear?
Common causes include a malfunctioning exhaust temperature sensor, low-quality fuel, issues with the DPF system, or exhaust leaks.
4. Can I drive my Cadillac with a P244C code?
While it might still be drivable, ignoring this code can lead to DPF clogging, reduced engine performance, and potential damage to the exhaust system.
5. How do I fix a P244C code on my Cadillac?
Repairs may involve replacing a faulty exhaust temperature sensor, cleaning or replacing the DPF, repairing exhaust leaks, or ensuring proper fuel quality.
6. How is the P244C code diagnosed?
A mechanic will use a scan tool to check sensor data, inspect the exhaust system for leaks or damage, and verify the DPF regeneration process.
7. Can a clogged DPF cause the P244C code?
Yes, a clogged DPF can prevent proper regeneration, leading to low catalyst temperatures and triggering this code.
8. Does low fuel quality contribute to the P244C code?
Yes, low-quality or contaminated fuel can disrupt the regeneration process and cause issues with catalyst temperature.
9. What tools are needed to troubleshoot a P244C code?
Diagnostics typically require an OBDII scanner, a temperature sensor tester, and tools to inspect and clean the DPF system.
10. How much does it cost to repair a P244C code on a Cadillac?
Repair costs vary but can range from $100 for sensor replacement to over $1,000 if the DPF needs to be replaced or extensively cleaned.
