BOXIOxygen O2 Sensor Compatible for Buick for Cadillac for Chevy for GMC Vehicles - Lucerne DTS Escalade Suburban Silverado Tahoe Yukon | Replace# 12562866 12597990

I could not use this item. After purchasing I realized the plug did not fit properly. I found that some trucks have a white connector and others have a black connector determined by whether it was built in USA or Canada. Mine was white so I had to order another. Be sure to check yours before ordering.

Put it in pulls up a code saying o2 sensor circuit range frequency low so I replaced male connecters and still same issue imma replace my entire wiring harness and see if that does it if not I'll be back to right a full review

The unit fit good and plugged right in to a a 2003 Buick

Pero me da falla en la ECU de que no funciona

I liked that they were perfect fit and they work great I bought them for a 2000 suburban 1500

Didn't work.

Oxygen sensor not working. The resistance of the heating circuit is 4 ohms, and the part number 12562866 should have 16 ohms.
