Exhaust Back pressure error....
Hey guys
Today I was riding around the city and stopped at the grocery shop to get some bananas. Went back into the car and bam no power.... gears shifts at 3k and my 190HP remapped car was slow as a snail... Tried the trick with the engine on/off but the third time, a CEL appeared... Very frustrated I went early home to pick up the laptop and found that error stored:
It says that the Exhaust Back Pressure Sensor is faulty and readings are out of range.
It is an OM651 engine on a facelift w212. As you can see from the screenshot (sorry for the none-English language) the error was stored during key on with engine not even running. I guess either a faulty sensor or shorted wiring. The funny part is that the readings seem normal. Cleared the error and now the car is back to normal....
Is it the sensor dying or something else?
I also had a dirty MAF sensor which was messing with the fuel trim or whatever it is used for. Cleaned the MAF with a MAF cleaner and reset the air sensor adaptation and the car seems to be running normally since then. But that b60 error is a strange case if it happening on key only.
Any advice would be appreciated.
