More 02 sensor issues.

1997 ZJ 318 motor.

I keep getting a check engine light related to BANK 1 SENSOR 2 (before cat o2 sensor). It says B1 S2 High Voltage. So I went and replaced the sensor. For about 2 days the light stayed off, now it is back on for the same sensor, same reason.

Any thoughts?

Bank 1, sensor 2 is the AFTER cat. conv. o2 sensor. Bank 1 sensor 1 and bank 2 sensor 1 are before catalytic converter.... you replaced the wrong one. :flipoff:
