I recently got a P0051 O2 sensor code on my 2006 6cyl Tacoma, replaced sensor, cleared code, still have ck Eng light. Is there anything that can be done to fix it?

Are you sure you replaced the correct sensor? P0051 is for the driver's side upstream sensor.

Otherwise you likely have a broken/corroded wire.
