The check engine light has been lit up on the sprinter van for a few weeks now. Since in New Hampshire this will cause it to fail the state inspection, and that inspection is due on the van at the end of the month I figured it was time to get that taken care of.
The code reader showed a code P0546 which was something about an exhaust temperature sensor. I did a little research and found out about 4 different sensors on the Sprinter van. I had heard that occasionally they get covered in carbon and just need a little cleaning. So, I attempted to pull out the first one to give it a cleaning…. and of course I SNAPPED THE DARN THING OFF!!!!!
So I had to fix that with a little JB weld (will see how successful that is) and then did some more investigation. Of course I found out that the problem wasn’t with any of these 4 that I had found out about but there is a 5th sensor which is MUCH harder to get to. This one is on the turbo which is on the back of the engine.
Anyway, managed to get it out, new sensor has been ordered and should be here in a couple days. Fingers crossed that this actually fixes the problem and I can get the van through the yearly inspection.
