BMW DTC P244C – Exhaust Temperature Too Low For Particulate Filter Regeneration (Bank 1)
DTC P244C meaning on BMW
DTC P244C on a BMW indicates that the exhaust temperature is too low for the particulate filter regeneration process to occur in Bank 1. The particulate filter is designed to trap harmful emissions and periodically goes through a regeneration process to burn off the trapped particles. When the exhaust temperature is too low, this regeneration process cannot take place effectively, leading to the DTC P244C fault code.
BMW DTC P244C symptoms
Symptoms of DTC P244C on a BMW may include reduced engine performance, decreased fuel efficiency, the illumination of the check engine light, and potential black smoke coming from the exhaust. Additionally, the vehicle may fail emissions tests due to increased emissions output.
BMW DTC P244C causes
The causes of DTC P244C on a BMW can vary but commonly include issues with the exhaust temperature sensor, a faulty particulate filter, a malfunctioning exhaust gas temperature sensor, or problems with the engine control module (ECM) that regulates the regeneration process.
BMW DTC P244C seriousness
DTC P244C should not be ignored as it can lead to long-term damage to the particulate filter and other engine components. Continued driving with this fault code present can result in increased emissions output, reduced engine efficiency, and potential engine damage over time.
How to diagnose DTC P244C on BMW
To diagnose DTC P244C on a BMW, a mechanic would typically use a diagnostic scanner to retrieve the fault code and then perform further testing to pinpoint the exact cause. This may involve checking the exhaust temperature sensor, inspecting the particulate filter, testing the exhaust gas temperature sensor, and examining the ECM for any faults.
How to fix DTC P244C on BMW
Fixing DTC P244C on a BMW may involve replacing the faulty exhaust temperature sensor, repairing or replacing the particulate filter, fixing issues with the exhaust gas temperature sensor, or reprogramming the ECM to address any control module issues. It is recommended to have a qualified mechanic perform these repairs to ensure proper diagnosis and resolution of the fault.
How to erase DTC P244C on BMW
To erase DTC P244C on a BMW, a diagnostic scanner can be used to clear the fault code from the vehicle’s ECM. Once the underlying issue has been addressed and fixed, the fault code can be cleared to reset the check engine light and ensure that the vehicle is operating properly.
