1997 Ford Ranger Question: Reset the check engine light
To reset the Check Engine Light, you can try disconnecting the Battery negative cable for 2 minutes, if you do not have a scan tool. If the light comes back on, then you need further diagnosis. Why did you replace all the parts? What were the codes. If you just try parts to fix a code, it could take forever because there are hundreds of codes just for a Check Engine Light. I would have someone scan the computer if the light comes back on. Also, you need to drive the truck for a couple of days to reset the computer after the codes are cleared. It is called a 'drive cycle'. It is pretty complicated, so I advise just cold starting the truck and doing some city and highway driving. Your truck will NOT pass smog with the Check Engine Light on or if the computer has not had its monitors properly reset after a code is cleared ( drive cycle ). I do Smog in CA and this part is universal in all States. - dandd
