Asked by Bassam Mar 04, 2010 at 02:53 PM about the 2005 Chevrolet Silverado 2500HD 4 Dr LT 4WD Extended Cab SB HD

Question type: Maintenance & Repair

Check Engine light came on, took it to Autozone, and code came with O2 sensors (all four) were bad.  This does not make sense to me for all 4 to go bad at the same time.  I asked if they can reset the code, but they said it was illegal to do so.  My next move is to disconnect the battery and see what happens.  Any thoughts?

Other problems could be causing it to think all four are bad. Typically it is something emission related like the a blown fuse on something like the 02 sensor heaters. What error code do it give?

You can do it with a code scanning tool or by unhooking the battery for a few minutes.
