For those that research this code; I had cleared the code before posting, twice, but it still came back. 4 days ago, I removed the Derringer connections before going the pressure switch route. I ran the truck hard from stops, moving, started restarted, everything I could do to make the check engine light come back on. It hasn’t. So either the Derringer connections were bad or the Derringer itself developed an issue after about 3 years of use. Using the iDash, before I removed the Derringer, the FRPs were jumpy and below what was commanded. (Checking numbers solely with iDash). After Derringer removal, FRPs were all steady and inline with what was being commanded.
Called Banks, explained the issue, they sending another Derringer. The rep was typing the whole time while we talked and never balked at what I was saying. Just got quiet for a few seconds while he read and said they will replace it. Wonder if they already knew. I will reinstall the Derringer as I like the performance improvements.
