I've been having an issue with my 18 zl1/heavily modder that I believed was an ignition problem, plugs, wires or coils but was not throwing any codes. But today I finally got a code P012B something about supercharger inlet pressure sensor. Trying to figure out what the cause of this could be? Thank you

This is a diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles with a supercharger.

Could be a wide range of any of the following - Defective supercharger inlet pressure sensor Broken or damaged wiring harness Problem within general electrical system ECM issue Pin/connector problem. (i.e. corrosion, overheating etc.) Clogged or damaged air filter. Maybe get a good dealership that has a GM performance shop and get them to look into it. It’s a hit and mess finding this problem, try a part and deduct.
