Hi guys,I'd like to pick your brains about the service throttle code. I had it last month,cleaned the the Map sensor(plugged pretty bad),ran okay until last week. I cleaned it again ,just a light coating. Cleared the code and it popped up again 1 mile from home. What's going on?

I had this issue. Cleaned MAP sensor like you said. Was pretty carboned up. Still had the issue, basically no turbo and truck could barely hit 70km/h without revving quite high. Was a -25°C day and did 750km driving prior too this coming on. Also, did not have a winter front on it at the time.

Solution for me was cleaning the MAP, clearing codes and letting the vehicle thaw out in a warm shop. Ran like a dream after that. Since then I haven't had that come back (2 months) and I've also purchased a winter front and deleted the truck (def system kept freezing and failing but not anymore).
