I have a 2002 Chev. Silverado 1500 with the 5.3L v-8 engine. Can you tell me how many O2 sensors it has in the exhaust system? I have been told four, but I find that hard to believe.
Service engine light has come on and I took it to Auto Zone to see what the problem was. I was told an O2 sensor was bad, so I put in a new one.
Light remained on so I went back and was told it was a different one, so I switched the two that I could find. The light remained on, so I had it turned off and then it came on again. When I had it turned off, they looked on their parts computer and it said that there are 4 sensors. Is this correct?
have the same problem?
