I have a problem, code 41. 02 heater circuit. I have replaced the 02 sensor and the code will not go away. What am I missing. I cleared the ECU as per the DIY in another thread. Thanks for the help,

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956
Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

what brand oxygen sensor did you replace it with? -
A Bosch was all that was available. Check the previous post. I am getting four long blinks. I cannot find a code 40 anywhere?Comment

i did read, thus why i posted. you first post code 41 which is indeed what you stated. then you go and say code 40
and you are sure its just 4 long blinks and not one short one?
is it the universal one that you have to splice in? or the "oem"
the problem lies within the o2 sensor, i am speaking from experience, if you go with a ntk or denso o2 you should be good to go

my bad, I had a code 41 before I changed the sensor. The light was still on after replacing it and clearing the ECU. I assumed the 41 was still there. I just went out and rechecked it. 4 long blinks. No short ones. So is this a code 1 and what is that?Comment

The blink and the pause appear to to last the same duration. So blink, pause, etc. It cycles 4 times.Comment

Sorry no vid available. After thinking through the process, it must be a code one. Are the Bosch sensor's that bad? I am trying to sell the car and that is all that was available on hand. I could special order a different brand. This is holding up the sale of the car. What about the connectors up by the strut tower on the pass side of the car? Any known problems with them?Comment

Oem replacement sensor. No splicing.Comment

grab one from a junkyard if you can just for the sale
and you reset the ecu by removing the 7.5 fuse? how long did you have it out for?Comment

I have let it sit for at least 10 minutes each time. I have thought about the wrecking yard swap before. BTW, thanks for the help.

your welcome. i would suggest just picking one up from a junkyard, and just throwing it in there since you are selling anyway
disconnect the negative battery cable and see if that erase it. then drive it around and see if the code comes back

I would suggest to clear the code, test drive it, and if it does not recode, then it is fine. but if it does recode, then you may have another problem, such as fuel supply system.
