check engine light
new member here, great messageboard (been looking for one for awhile)
i have a 00 GMC Seirra, and the check engine light is on, i have found out that its the 02 sensor and i was told it was 'both' of them, but my truck has 4 of them. someone told me the ones behind the cat convertor are the ones that make your light come one, if anyone can confirm this, it would be great. thanks. |
