Ok so in the last 5 min I made something work, using a MOSFET tied into a resistor representing the max resistance that we need to see for the EGTs, I can use the mosfet to ramp the resistance from OL al the way down to the 5ohm resistor at 5vdc, it works and I can step it in .003 ohm resolution. Poor engine performance; Poor . I can't live with the van as it is 08 . Otherwise issues like you describe will occur. 1 0 obj

Locate the EGR differential pressure sensor (next to the EGR valve), remove the screws and perform a visual check on its pressure ports. This HAS to make a diff in how it runs though..theres no way it can run right without an accurate reading, can it? Verify your repair and continue to the steps below.

Differential Pressure Sensor (DPS) - Exhaust Pressure Sensor - RPF Pressure Sensor In the exhaust system of your vehicle, the differential pressure sensor measures the pressure upstream and downstream of the diesel particulate filter, i.e. Cummins Differential Pressure Sensor (DPF) For Cummins ISB 6.7L Diesel Engine EGR Delta. Active and stationary regeneration of the DPF will be disabled. The ground and signal ports are usually located on opposite sides from one another, so youll leave the middle port empty. I'd strongly suggest getting either an "OBDLink" cable or Bluetooth device rather than trying to use an ELM327 device to connect Multiecuscan to your van, MES seems to have no end of issues with the cheap ELM units.
