02 Sensor
I can't find the post I made earlier, so at the risk of looking stupid, I'll copy and paste it here to see if it shows up. Sorry if it gets posted twice.
Here it is:
I'm back. I did the check engine light flash sequence where you insert the key without starting the car and turn it on, off, on, off, on, and count the flashes. It gave me a code 51, which according to the computer code list I found on the internet for my car (94 Chrysler LHS) means that the oxygen sensor is stuck at lean position. I realize that if I've driven it this way for a while, it could have damaged the catalytic converter. But wouldn't I have noticed something if it's been this way for a while? And why does it always give you the # 12 code first (Memory Standby Power Loss - battery cable disconnected)? Is it because I initiated it by doing this procedure and that's the code you should get first? I checked it a few times and each time I had 1 flash, pause, 2 flashes, pause, 5 flashes, pause, 1 flash pause, 5 flashes, pause, 5 flashes pause.
I'm still taking my car to my mechanic, hopefully this week if he can work it in, but I'm trying to get a handle on repair costs, especially since I just finished with all the Christmas expense. How accurate is the key code procedure? How expensive are catalytic converters? Lastly, could some other malfunctioning part be causing this? Where is the 02 sensor located, is it easy to get to as in, can my hubby replace this part or are we better off just taking it in and hoping it doesn't lead into a lot of parts having to be replaced? I know that when the map sensor went out it was right on top, easy to get to and looked like I could even change that part myself.
Thanx for all of your input.

I found my post and the response. I'll study it.
Thanx,
