Installed A/C Compressor Bypass Pulley. Check engine light stays on now. Is it possible to resolve check engine light with A/C Compressor Bypass Pulley installed?

My car has an automatic transmission.

Hi Alex. Thanks for contacting us today. Unfortunately, when any bypass or non-OEM system is installed such as an AC bypass pulley, it’s not possible to reprogram the ECU to delete warning lights. It’s one of the drawbacks to installing these type of aftermarket components.
