Drive a few days with the gas gauge between three quarters and one quarter full. That will allow the computer to run the diagnostics on all the systems and set the readiness monitors. You must have more than one readiness monitor not set to fail inspection. But doing the above procedure will set them. Hope that helps! Jim
