What's up,
Well as everyone has experienced (or will experience) on this board, my car was throwing a code 41. Since my car was already running on 62,000 miles I decided I might as well change it. So after I get it changed at the shop I start driving and I see the CEL light come on and I think "ahh that's cool I can just clear it myself by disconnecting the battery or pulling the fuse" so I go home. Well after disconnecting both of the cathodes of the battery (and pushing on the brake pedal to clear any electricity in the lines) it still comes on after my engine is running for a minute. So I go to the other method and pull my 7.5 amp back up fuse for about a minute.... and BAM the light still comes on after the engine idles for a minute. I check the code and yeah, it's still throwing code 41 so now I come to two possibilities:

1. Somehow this damn car has a memory and I cannot clear this CEL code unless I get someone with a diagonostic tool to clear it for me.

2. The shop didn't install it right and it's time to cause a ruckus. I thought it might be this because they had a hard time putting the new sensor in, and a couple of times it bumped into dirty hoses.

My question is if anyone was ever able to clear a code 41 using the battery/fuse method. I've read on only one board that you cannot clear a code 41 using these methods, but I'd like to know if any has done it.
Well thanks for reading my novel and I hope if you have any info you can post it up for me.
Thanks,

got a new O2 sensor installed but I still can't clear the CEL by disconnecting the battery/fuse! HELP PLEASE!

 

did you check the code with the flash lights routine or with a diagnostic tool?

my first response is that a new o2 sensor didn't fix the problem...

 

Both of the methods you treid should have cleared it. You got hosed and got another bad 02 sensor.

 

like Ricey said it should had clear the code with the methods you tried. now did you check that it got plugged in. take it back to the shop the install and tell them to replace a new o2.

 

did you get oem or universal??

get oem.... even if it's used, it'll be better then a universal sensor...

 

What's up,
Yeah I'm pretty sure the sensor was crap. I saw the box and it was all generic looking, but I needed it (since I work 9 to 5 on weekdays) and this was my only chance to get it fixed. Well time to cause the ruckus tommorow.
Thanks,
Jay

 

Those methods both work but a sure way to reset the codes is to disconnect the ECU for a couple of minutes and if that still dont work then just like everyone else said, Ya got a crappy *** o2 man.

 

What's up,
What I think I'm going to do is order a OEM one from oxygensensors.com and then have them install that and refund the crappy o2 sensor they gave me. That piece of ---- cost me more than a hundred bucks. I'm sure I can run with the CEL light on for a couple more days since I know it's just the o2 messing up and nothing else.
Thanks,
Jake

 

Since the cel comes on right away that tells you that the sensor is not even hooked up or faulty all together. I would just check the plug.

 

Unplug your ecu for a few minutes.

 

Resetting the ECU by pulling the 7.5A fuse or the (-) battery cable will both work.

If the instant you turn the key 'on' (not started), and the code persists, then either the heater section in the O2 is duffed, the wiring is corrupted, or the internal circuitry of the ECU that controls the heater section has taken a dive.

You need a multimeter and Helms in order to diagnose this problem (the wiring or O2 itself). If the ECU is shot, replacement is the only option there.

 

What's up,
Good news. It ended up being just what you guys said... a bad O2 sensor. At the shop they were holding another package of the generic O2 sensors to put into my car, but they knew it was a piece of crap so they sent a guy to buy a OE one haha. Well thanks for all the help!
