GM General Motors Genuine Parts 213-1552 Heated Oxygen Sensor

Although Amazon indicates that this does not fit on a 2005 Chevy Impala, it is the part# called out in the AC Delco catalog. It fits perfectly and solved the problem. The old sensor had a high ohm reading on the heater.To save a lot of headaches, always use the manufactures OEM replacement oxygen sensors.

I have a 2007 saturn aura xr 3.6l and Amazon says that it will not fit/work on my vehicle. But I did some searching and this part is the oem replacement part and will work for my vehicle. It was very easy to change on my bank 2(front closest to radiator) and took my code away and hasn't came back on and its been a week.

My o2 sensors were getting lazy I bought Delphi the original o2 sensors that came with my Buick lacrosse and bang threw the cel light bought an AC delco upstream and downstream original heated oxygen sensor and the power to MY car came back don't let anyone tell you the gas mileage isn't affected that much by bad o2 sensors most say you can't notice my car was getting 10.5 mpg before I changed them out and now I'm getting almost 17 do buy AC delco the impedance out the box is 15 Delphi was 10.4 and others are around there or less just spend the money its worth it. I went through 6 different types Bosch spectra off brand all kinds of different o2 sensors but AC delco is the only one that worked for me

02 Sensor 2005 Buick Lesabre. My 02 sensor has a female connector not a male connector. Even the website says, this will fit your vehicle.

2006 Pontiac G6 coupe post cat O2 sensor. Car had been throwing a code for the heater element resistance being out of range, so I bought two sensors and replaced both banks' post-cat ones. Thought all was well, but the check engine light came back on. Note that these were sensors bought on amazon and listed as being a fit for my car, but they were not these acdelco ones. Anyway, after a lot of troubleshooting and head scratching, I finally bought these ones in a last ditch effort to fix the problem. They worked. My scan tool shows the onboard diagnostics is now reading the resistance right in the middle of the allowable range. If you're getting p0054 and/or p0060 codes and are going to replace the sensor, this is the one you want.

Had one issue and that is the plug was slightly different. Had to swap the old plug with the new to make it work. Other than that the code has not come back and it was a great price for the part.

Oem AC Delco, worked perfect for my 2006 Pontiac Grand Prix GT (works on non gt models too)

Amazon Said it doesn't fit a 2004 Buick regal. I installed it on a 2004 Buick regal gs and it fits and works.
