LT1 trouble code 44...

04-15-2005, 01:44 PM

Hello, my 95 z28 SES light came on for about 15 seconds and then went off. It has only done it once that I know of.
It read code 44: Left O2 sensor was under .2 volts for 50 seconds of closed loop operation.
I replace the O2's about 4 weeks ago so I dont understand why this happened.
Do you guys think it was just a little hiccup or what. Should I replace the new O2 under warranty.
Thanks

I would reset the computer and see if it comes back.

^ i agree, you could also check the connection and make sure the O2 is not loose.
