<p>[QUOTE=&quot;BoxCarKidd, post: 11752487, member: 151415&quot;]2007 IHC 4300.</p><p>&nbsp;&nbsp; It has a yellow triangle comes on the dash and it shuts off. Sticker on the sunvisor says that means the dpf needs regeneration. It will not do a forced regen with the dash switch. Scan tool says it is good and does not need regeneration. </p><p>&nbsp; The BAP always reads 13.9. This is the only truck like this here so I have nothing to compare it to. The actual barometric pressure here today is about 30. Could this be the problem? The ECM is trying to compensate for bad information? Bad part is the BAP sensor is built into the ECM. Makes for kind of expensive parts swapping.</p><p>&nbsp; Then does a new ECM have to be flashed by the dealer for the truck?[/QUOTE]</p><p><br /></p>
