hey guys im not really new here but never really posted anything before i just have a quick question i have a 01 max and i went to do my inspection today and it came up with cat monitors not ready i replaced my cats last year and also reset my ecu to ease the codes i had i dont have any cel on and there are no codes on my car any idea what this could be

 

Did you erase the codes immediately before your inspection? If so, there is your problem. You need to drive the car after clearing codes to get the monitors to start scanning again. Usually about 50-100 miles.

 

tom i been driving the car for a year since my last inspection i never had to drive for that long the most i ever did was 100 miles to reset everything repairs was done last year around this time cus after i did my inspection last year my cel came on so i fixed it and reset my ecu
