2012 Chevy Equinox 2.4L Aftermarket HPFP Failure P0191 & P0172 - How To Diagnose with DATA PIDS ONLY

Описание к видео 2012 Chevy Equinox 2.4L Aftermarket HPFP Failure P0191 & P0172 - How To Diagnose with DATA PIDS ONLY

This chevy equinox started out with a loud exhaust complaint (the customer insisted on the exhaust manifold to be replaced) and eventually led me to an aftermarket HPFP failure. The vehicle couldn't even be driven very far without stalling or going into limp mode at relights and stop signs.

The customer had replaced the intake and exhaust solenoids (Dorman Brand), High Pressure Fuel Pump (Oreillys Unknown Generic Brand), and the fuel rail pressure sensor (Standard Brand).

Watch how I narrow down and find out what's causing the codes.
