well this service engine light just came on this morning for the first time on me. i just started up the truck and backed out of the garage and it pops on and stays. i used my programer to check the code and i just reset it in hopes that it wont come back on BUT it probably will. question is what should these sensors read and do i check them while running or just ignition turned on but dont start motor?
and if it matters its a 1997 C1500 2wd 5.7/auto truck.
my programmer can read the O2 sensors but hell i dont even know what they are suposed to read or even if i read them running or motor not running.
and hell i dont even know where the bank1 sensor2 is.
i tried to get a video of the sensors running but my camera phone sucks so bad you really cannt see much! ill have to try and get my good camera for a video here in a minute.
always sucks when the check engine light comes on any vehicle and this is the first time its came ON in my truck. 202+K miles on her right now so i know things could use replaced but ill hit them when they come as long as they check good for right now. i just dont want my trucks gas milage or performance to hurt any from this O2 sensor if it does pop back up in dash as bad!
help me figure this thing out and hopefully where the ******* is at so i can replace the right one!
