Oxygen Sensor Reviews - 2003 Chevrolet Avalanche 1500
Bosch | 15284
 


Very satisfied, the sensor works righteway, the shipping was fast. I will recommend this company.

Bosch | 15284
 


I am not sure if this is the problem but I replaced the sensor and cleared the codes. 80 miles later the check engine light is on for the same sensor. Might be a bad wire job but could be something else. I will have to do other checks to make sure.

Denso | 234-4668
 


I received the part pretty quickly and it was a direct fit replacement on my 2003 Chevrolet Avalanche. It corrected my P0161 code. Thanks!

Delphi | ES20013
 


An absolutely seamless process of access, review, ordering and attentive shipping (3 days to my door). Nothing confusing at the site. And, whew!--phenomenal savings compared to local dealer/parts servicing. Everything worked the first-time as advertised. I'd have no hesitation whatsoever

to utilize Parts Geek again. Great resource!
