All of a sudden truck seems to have a sudden loss of power and is throwing this code P2535, but no check engine light. Tried clearing the code but still having the issue. Used to have the Cobb tune but haven’t installed it in a while now.

Ignition switch voltage error. I’d make sure you have a good battery and alternator as first steps.

P2535 is ignition Switch Run/Start Position Circuit High. It sets when the PCM detects voltage on the crank detect circuit while the engine is running. Do you have anything aftermarket spliced into the ignition?

Nothing spliced in, just lights tied into the aux switches
