code PO272

Finally got my insight hooked up and decided to check for codes. Came up with this code, #4 contribution/balance. Any idea what this means? Also I noticed with my truck running my voltage is high 11's low 12's. That sounds really low to me. I replaced both batteries and the alternator about 3 months ago and have not had any trouble since. Maybe the insight was a bad idea because now I get to see whats wrong with my truck

#4 cylinder isn't doing it's fair share of the work, the PCM realizes this and sets a code.

It could be anything from a injector going bad, to a chafed wire harness, and anything that has to deal with that cylinder to run 100%.

Your volts seem low to me, you might want to have your batteries and alternator load tested. Have you checked your FICM volts while cranking, KOEO, and KOER.

FICM volts are perfect. 48 almost always. Dips to 47.5 once every 30 seconds or so.

Just manually checked the batteries without the truck running. 12.15 on one and 12.16 on the other.

Batteries need to be check when all cables are disconnected. Our batteries run in parallel which means when you check them while they are connected, the stronger battery will give you a stronger reading that will hide the weaker battery reading. Does that make sence?
