Mazda 6 DPF Regeneration Procedure. A faulty DPF can be the cause of excessive smoke or a slow vehicle. If the dpf regenerates itself in a short period of time, then it can save fuel. However, if the regeneration takes more than 40 minutes, it may cause the engine to stall and cause a loss of power. Meet the Experts. Unable to perform dpf regeneration on Mazda BT50. 2015.

The No. 3 exhaust gas temperature sensor (DPF temperature) is a kind of resistor, which has characteristics to reduce its resistance as the DPF temperature rises. Therefore, the sensor output voltage varies with the DPF temperature, and becomes lower as the DPF temperature rises. To diagnose a faulty exhaust gas temperature sensor, consider the following steps: Conduct an electronic test and read any fault codes using a diagnostic tool. Inspect the connectors for signs of corrosion or loose connections. Check the wiring for any breaks or damage that could cause a short to the ground. 303K views 10 years ago. 2 minute solution to flashing DPF light. This light which should warn that filter needs changing also acts as a service indicator light but those clever boffins at Mazda finally fixed the re-gen issue with firmware EU 59.00.502.

The very latest firmware version is EU 59.00.532 but really, as long as you're on EU 59.00.502 (or the latest EU 59.00.532), you will see an end to these bloody re-gen, oil contamination issues It could be faulty and still working but not correctly. By sending the incorrect data to the ECM, generating more PM / carbon, stopping the DPF regeneration process, could result in a blocked DPF. The MAP/MAF sensor is an essential part in delivering the correct fuel/ air mixture to the engine. If it fails or begins playing up, the ECM cannot .
