When the check engine light initially came on I had the 'applicable' sensor replaced, then a week later the light was back on. I replace the gas cap (3 times). It comes back on and per the mechanic I replace the fuel tank ( only way to get to the sensor) and fuel pump. I was able to go 5 days and guess what the light is back on. I have replaced everything I can and still the light comes on. I can't be the only one with this VERY EXPENSIVE problem. I service my vehicle routinely and overall it is in very good condition.
