High voltage O2 sensor Circuit

**ss~zoso~ss** · 06-16-2008, 11:47 AM

I keep throwing codes for high voltage bank 1 and bank 2 rear O2 sensors , i have removed the cats, with an ORY and O2 Simms, are my simms going bad and causing these codes, the simms have worked great for about a year with no problems,

also if i erase the code it doesn't come back on until another 50 miles or so, please help

thanks,

Jeff

Sims are probably bad like you mentioned. Just get the codes tuned out.

do u think the car runs any different if the SES light is on for those codes, ie if the SES light comes on again will the car perform any worse if i just stop erasing them at autozone?

If the codes are for those rear 02s, it won't make the car run poorly if the SES light is on. The only reason to get the light itself turned off at autozone is because its annoying you.
