EGR and EVAP monitors

I cannot get my EGR and Evap monitors to register, despite driving my drive cycle listed in my owners manual at least six times from an eight hour rest each time. I scanned my vehicle and sent a start command to test for vacuum leaks but that did nothing to fix.

I initially used my scanner to clear a trouble code for low coolant temperature ( either the thermostat was sticking open at times or the manufacturer put the wrong temperature thermostat in for the sensor ) After that I needed to pass emissions for plate renewal. It failed due to not ready for test. I drove it the drive cycle as stated in owners manual from a cold start each time, a total of six cycles. I cannot get two monitors to be ready and I can only have one not ready to pass. I sent command to start vacuum test (via scanner) but that did not change anything. My EGR and Evap monitors both show inc (not ready). What can I do? I already drove it over one hundred and fifty miles through those six cycles.

Great site!

This code is set when the thermostat is stuck open which will cause the monitor not to reset. Here is a guide to help you see step by step how to replace the unit and diagrams below to show you how it will be on your car:
