Default MAP sensor codes with JB4 installed - 11-20-2020, 09:00 PM

I have an S55 JB4 that is causing a CEL with two MAP sensor codes. Iím wondering if I may have touched the USB cable to the positive jumper lug and fried it. The codes were:

* Ambient pressure sensor shorted to positive
* Boost pressure sensor shorted to positive

Sorry, I forgot to note the numeric portion of the codes. I removed the JB4 and cleared the codes and the car seems okay. What components on the board do I have to replace?Thanks!

If the car runs OK with the JB4 out then the TMAP ground is likely OK. You can always send in the JB4 board if you want us to test it out on the bench.

Yep, car is okay with JB4 removed. Do you sell replacement boards? I might just order one since that seems to be the issue. Thanks!
