Now before everyone yells at me, I did try and search around for an answer to this question. But with 2k+ hits on the search and finding nothing in the first hour of reading I give up looking. lol

Question #1:

Got hit with the good old check engine light and checking the codes got these two;

Code 13 - Oxygen Sensor open or shorted circuit
Code 44 - O2 Senser - Rich exhaust

Now I know and understand that if a high voltage signal comes from the senser you get a Code 44, but what does Code 13 really mean, since I can't find any data on it. Does it mean the senser needs replacing or is there something else causing this code? The reason I ask is I found that Code 55 mean'* the same as code 13 in a way and also Code 61 mean'* the O2 signal is faulty.

Question #2:

Now if I need to replace the senser I keep reading NOT to use a Bosch senser. Now asking around town here, everyone has the Bosch and anything else is special order. Now when I questioned how Bosch was not good for the engine I was told Bosch makes all the other brands too, like AC-Delco etc. Now is this just some line to sell the Bosch, or do they really make for the other brands also?

I have used Bosch, AC Delco and Standard O2 sensors. All work, but I noticed the most active sensor (high cross counts) was the Delco. Bosch may make sensors for other brands, (Mallory makes Accel and Jacobs parts) but it doesn't necessarily mean they have the same spec'*. The Delco and Bosch definitely look different and the diameter of the actual sensor is larger on the Delco.

Hey, another person from Winnipeg with an '89 SSE.

I got my O2 sensor off ebay, it'* the AC-Delco AFS-20, and that is what everyone else runs as well. I beleive when I called Part Source/Canadian Tire they said they could order it in, but it would cost $40.00. I got the AC-Delco shipped to me for $25, and so far it'* been worth it.

Cool, then I guess I will order in a AC-Delco then from somewhere. Thanks for the info guys and hello Capt. Let me know how the changing of your balancer goes so you can come change mine also.
