*** NOTE ***
There is currently a bug in the JB4 software that may trigger a IAT sensor fault randomly every few days on some vehicles. Code clears when restarting car. We're currently investigating possible causes and will provide the solution (either via firmware update or updated control board) to all JB4 SENT BETA customers once resolved.
