Default CEL With No Codes - 06-30-2022, 12:22 PM

Prior to the following, I have been running JB4 with BMS E85 BEF for two years with no issues.

A couple of weeks ago, I installed a ******* DP and used MHD to fix it. About a week after that, I installed a CAI and FMIC.

Last weekend, it started giving me a CEL with code P10BA. I've tried searching that code but came up with nothing. I clear it and it eventually comes back.

Yesterday, I got a CEL with P10BA, P481D and P2008. The only thing I found was that P2008 indicates: intake manifold runner circuit has an open electrical connection bank 1

Another strange thing was that my oil temp gauge in the cluster stopped working. The JB4 app is showing oil temps however.

I deleted the codes using the JB4 app and the oil temp gauge started working again.

Now I have a CEL but the JB4 app does not detect any codes. Clearing the codes does nothing. I disconnected the battery for about an hour but the CEL persists on startup.

I am grasping at straws here to see what guidance this community has. Any thoughts would be appreciated.

I've heard some folks have issues after installing cai. Perhaps reinstall oem and see if codes persist. Just a thought.

Try scanning with an INPA or another tool that can read more than just the DME.
