I keep getting code p0141, b1 s1 02 sensor. I have replaced the sensor and the light keeps coming on. The wiring looks good, but the light will stay on. What should I do?

Have you cleared codes?
THE LIGHT WILL NOT GO OUT UNTILL THE PROBLEM IS FIXED AND YOU CLEAR CODES.

Codes do not say repace sensors.

The code is for a heater circuit on bank one sensor 2.

Are you sure you are on the right sensor?
Wher was the one you replaced?
Check for heater circuit voltage and ground to that sensor.
Is fuse to it good?
Is wiring and plug in good?

Check for battery voltage at the O2 heater,(Brown/Pink), wire.
If battery voltage is good, check heater ground,(Black), wire.
If both power and ground are good replace the sensor.

Good luck.
