2004 GMC Sierra 1500 SLE 5.3L Monitors
Posted to GM Driveability on 4/20/2017 8 Replies

Thank you for your help. This truck will not pass the catalyst, or Evap. monitors. Also it will pass the O2 sensor monitor, both heater and performance, and then when you park the vehicle overnight they both go back to not passed. I am suspecting a PCM problem...
