I helped a Forum member last month who had this DTC and I told him just to replace the bulb in the IPC…that fixed his so I’d start there !!…if you want remove that PCM connector and take a 12 volt test light connected to battery negative…touch it to pin 46…you will be giving the bulb a ground…see if the bulb lights…I may have mentioned this to you !!
Okay so I moved back up to the test bulb i wired into the underhood fuse box last week. I must have had too many beers when I put that in cause I had it on the wrong pin. Corrected that issue and now my check engine light is located by the battery. Hate me if you want but I'm not going back into the dash and opening the instrument cluster. This is its home and I'm fine with that.

You can do what you want but you won’t pass state inspection if your state has one !!…good luck !!
seems like it will though. Right? My bulb here is in the circuit correctly and the PCM driver detects the correct voltage when it runs dtc P0650. I have no codes on the PCM. Just a new location for the bulb.
I seriously doubt that will pass an emissions visual inspection
good point. I'll take my chances and if it doesn't I'll go from there. Round here I've never had the testing person do a "visual inspection". They hook it to the computer and if it passes it passes. Ive seen a car leaking oil and smoking.....they don't give a flip. 5 miles south in the next county there is no emissions requirement.
