O2 Sensor code P0133 on '96 Explorer - I've got questions
Just wondering if anyone can give me some info. My mom's '96 Explorer set a Check Engine light this afternoon, and took it into Schuck's to pull codes. What I got was a code P0133 - O2 Sensor Circuit Slow Response (Bank 1 Sensor 1). Anyone else have this happen? Are there any other tests I should do before proceeding any further? Where is this particular sensor located? This truck has the 4.0 and an automatic. Any info would be appreciated.
