Bad jb4 board? Persistent 2abd code

andyho123 · 09-18-2014, 12:32 AM

TMAP Sensors were replaced but 2abd code still persist with half engine light on.. Cleared but come right back on start up. Electrical test checked as well!!

Vacuum and pressure checked and no leaks. But threw 30ff twice!

I have done every services possible. Checked the jb4 connections as well, connectors were in correctly.

I have a feeling it's the jb4 g5 board getting bad....anbody can help?

Terry can. If the board is bad he will most likely swap it out for you.

Remove the jb4 and see if you still have problems would be the logical first step.

Took off the jb4. Everything is fine again. It was definitely a bad board
