Chevy C1500 Silverado. My check engine light came on and the code indicated a bad oxygen sensor after the converter. I ordered the part (cheaper than picking it up locally) and the day the part arrived, the check engine light went off BEFORE I INSTALLED THE PART. Now I am having trouble busting the old sensor loose because it is pretty well rusted in there and there is a frame cross member in the way of getting good torque on the wrench. But in the meantime, my dash voltage indicator says 9 volts on the battery and the clock reset to 12:00, and this sometimes causes the transmission to SLAM into first gear as well. I had previous electrical gremlins caused by a loose ground wire to the fender - - also really difficult to access! But I'm wondering if the oxygen sensor alone could actually be causing all of this electrical havoc this time? I haven't put a voltmeter on anything yet because it got dark out while I was fighting with the sensor. Will work on it some more in the morning.
have the same problem?
