Did you look up the code definition? A P0207 is the number seven cylinder fuel injector circuit is open.2016 Ram Power Wagon, all stock, around 168,000 miles on her. So, about a month ago, I started to get a rough idle in my truck. Then I got a low battery voltage message. I scanned the truck for codes and got a p0207 open circuit. The exhaust also had a rich smell to it, and I would see a small bit of smoke on startup sometimes, not all the time. About a week later I took it to AutoZone to test the battery and alternator and they said it all checked out good. About a week later, the truck died in the middle of the road. PRNDL were now yellow also and a check electronic throttle control system symbol/message. I cleaned the throttle body; however, it wasn’t very dirty. Still no luck. The truck would start but die after a second or 2. Took it to the dealership and was told I needed a new PCM. New PCM was installed, and the truck was good. So, I thought. About a week later I got the low battery voltage again. Dealership said I needed a new alternator. I installed a new alternator and roughly 2 days later I got the low battery voltage message again. Now, today, 17 Feb 2023, as I pulled into my work parking lot, PRNDL are yellow again and truck dies after 1 to 2 seconds again. I’m completely stumped here. Not sure if I have a short somewhere, bad ground or what. Any help would be great.
The rich smell is likely caused by the fuel trim percentage going high(er) because the fuel injector is not firing.
