    Oxygen Sensor voltage Stays between 0.35 and 0.55 volts for 60 Seconds. Engine was at normal operating temperature and had been running for at least 2 minutes after start with a throttle angle above 5%.

    that is code 13 anything i should be warried about? also i got code 12 but there is no 12!

    Drive over to any Pepboys, Advanced or whatever big box auto parts store you have in your area. They will scan it for free. if it is an o2 sensor its an easy fix.

    Code 12 just tells you the computer is there. It will always flash, regardless of whether there are any trouble codes. Check the wiring to the sensor, and if it's ok, just change the sensor. It is $20. The toughest part is getting it out.

    Do you have any major exhaust leaks upstream of the sensor?

    nope i just replaced the gaskets at my headers so i have no ehaust leak. im going to clear my codes when i dismount my plow in a few, see what happens if it trips again.

    the nice thing about the older GMs is that you can flash code them by jumping 2 pins without a scan tool, the bad thing is that it doesnt give you any data to compare
