So I had absolutely no codes. I pulled the fuse #8 that supposedly is for the 02 heater circuit along with a couple of other things. I drove the car around the block, turned it off, started it again and drove it a mile or so and I got a check engine light. Got home and checked it with the scanner. 7 codes. 1 for each of the heater circuits not heating (4 total) 0ne for egr solenoid, 1 for evap vent solenoid, 1 for purge control valve. So fuse 8 powers a few "engine controls". So I put the fuse back in cleared all the codes, which resets all the monitors too, and drove it around for a few miles. No check engine light. I checked for codes, none. I checked the monitors and they had all reset except for the same 4 that are stuck. So, this leads me to believe that the heaters in all my o2 sensors are working fine, or I would get a code. The wiring is all good too because that would set a code also. The computer is working properly. Also the other monitors reset easily so I dont think engine temp is an issue. I dont think the egr would set if there was an engine temp issue. Still has me stumped but at least I know a little more and for now see no need to unleash the parts cannon as it all seems to be working properly. Next Im gonna check my exhaust manifolds for cracks and leaks as I ve heard that can cause o2 problems. I know I have a tick that goes away after about 45 seconds in the morning when cold. And it is exhaust,not engine mechanical.</p></blockquote><p></p>
