Recently bought a truck and didn’t bring my obd2 scanner. Drove it home to find it has p0122, p0223 codes, I checked the voltages at the connector and all seem fine. I have a Maddox MR16 scanner and checked the live data while slowly and smoothly applying throttle and there were no spikes or anything out of the ordinary. Wondering if it’s the throttle body, another component on the circuit or a wiring issue somewhere. I forgot to mention, I have 0 drivability issues or idle issues. Throttle response seems very normal, it runs and drives as good as any other Silverado I’ve driven.
