elthomas195 Posted May 16 Report Share Posted May 16 I have a 2016 Ford edge with 3.5 L V6 It’s throwing a code of a P0430, new cats, new downstream O2 sensor, no other codes present. Any help would be nice. 1 Quote Link to comment Share on other sites More sharing options...
elthomas195 Posted May 20 Author Report Share Posted May 20 I just replaced my engine with a 43,000 mile engine that came out of a Ford Explorer 2019 model for some reason the ambient temperature sensor is not reading right and and bank 2 sensor 2 O2 is throwing a p0430, and all of the driver side lighting (headlight, park light) isn’t working. Has anyone heard of having to reflash the BCM and the PCM after an engine install. 1 Quote Link to comment Share on other sites More sharing options...
Wubster100 Posted May 23 Report Share Posted May 23 I don't see how the headlights are related to replacing your engine. Do you have codes for them? It sounds like the wiring to the headlight could have been damaged or not plugged in during the engine replacement. Quote Link to comment Share on other sites More sharing options...
elthomas195 Posted Wednesday at 11:41 AM Author Report Share Posted Wednesday at 11:41 AM Now to edit, the lighting issue is solved, but now getting p0036 and p0056, no p0430 anymore, new upstream and downstream o2’s, new cats, this thing is about to wear on my last nerve.

1004ron Posted Wednesday at 01:07 PM Report Share Posted Wednesday at 01:07 PM Measure continuity of both O2 sensors heaters and if that's good confirm voltage across the heaters. What brand and model O2 sensors did you install? Quote Link to comment Share on other sites More sharing options...
