97 Mecury Sable "Sensors not ready" problem -NYS inspection
Let me start by saying Check Engine light is NOT on.
replaced alternator last summer. Maintained by same mechanic for years.
I took car to my friends shop to get the annual NYS inspection and it could not be passed because computer read "sensors not ready". not clear which sensors.. computer isn't telling us. Car had been sitting for about 6 weeks, driven twice in that time. Started once a week to deter any mice. I did not need to jump it. Mechanic was not sure, thought perhaps battery weak from sitting, suggested driving it around for awhile and bringing it back. 3 weeks and 600 miles later brought it back and it still reads sensors not ready? My mechanic is trustworthy, a relative, and he isnt sure what it is and suggested I try to find info on line about it so I dont spend alot of money trouble shooting. If anyone can help us out we would greatly appreciate it. Can someone please tell me what would cause this / how to fix it?
