Engine/Transmission (1998.5 - 2002) Trouble Code P0236

[pharlacher]

I have been getting a P0236 for quite a while. I just put a new Map sensor in and I still get it. Truck runs fine. It will come on and go off after a few starts. I have a diagnostic tool for reading and deleting codes. It won't clear this one.



I have checked all the connections. I have a TST power-max 1. I still get it when I take it off.



Anybody know of anything else I could look at?



Thanks.
