My check eng light came on. Of course just prior to my smog check for license plate renewal.

I borrowed a code checker and it read the following
P0133
O2 Circuit Slow Response
Bank 1 Sensor 1
Calculated load
69.8%
Eng Coolant Temp 192degF
STFT Bank 1
0.0%
LTFT 1
-7.8%
STFT Bank 2
2.3%
LTFT Bank 2
-3.9%
Eng RPM
1824 RPM
Vehicle Speed
58 MPH

What is all this telling me? Is the Sensor bad? What is Bank 1 Sensor 1?
Any help or insight would be greatly appreciated.

 

What do you have? Need year and engine size.

 

Yea , you need to post what you have ..

Time to replace BOTH forward O2's..

 

I have a 97 F150 with a V6. I think it's a 4.2liter
