Took my truck for emissions/inspection the machine rejected my truck because my oxygen sensor and heater monitor were not ready. My tech told me to drive it so they would shut off. Its now been two months and they still will not set to ready? i dont know what the problem could be bad sensors maybe? im also not getting any codes! please help!

 

I am having the same problem. Did you ever find out what was causing the oxygen and oxygen heater monitor not to set?

Thank you
