Which sensors tell ECM to start regen, CM2250

[trdodd07]

I'd think that the temp sensors would play a role in it. DPF in and out temp sensors, DOC inlet temp, IMAP for monitoring boost psi for regens. If you've watched the video on doing a regen on insite that Rawze has made... all those sensors probably play a role in the process. Good question on which ones can signal the ECM to start one though. My guess is the dpf diff is the key player due to it monitoring the differences in pressure between the two points. Inlet and outlet temp sensors might signal a start if a tolerance threshold is exceeded between the two??
