Ok I had the following codes:

0707 - Rear heated o2
0903 - Evap Canister VCV
0304 - lol KS
0503 - Front Right heated o2


I've been messin with the EVAP for a while still havent fixed it, any suggestions would be great but not my main Q for this thread.

I replaced the FR o2 last night, PITA clips by the way... anyways, I heared this sets off the rear o2 so obiously I changed the front first.
Now the only code I have is 0903 - EVAP Canister VCV.
My question is simple, the o2 triggered the KS right? So likely the KS is bad but throwing a 'ghost code'???. I cannot get the KS code out of it now all i get is the EVAP.
I have a KS here to replace it with, just more of a curiosity thing than anything, and how can I check to make sure that (if I replace it) the new one gets rid of the problem??
Any help would be appreciated I'm a little lost on this sensor stuff!

 

I might b runnin into the same problem I got a bank 1 sensor 2 o2 I think goin off and my ks..... bought the ks even though I heard that o2 set it off cuz my car is driving dumb slow now so I just forget ill replace it...... can't fit my hand in there so its takin me a while.... I would recommend just changin it u bought the part newayz so it can harm but only help so do it.....

 

People tend to think that because the knock-sensor doesn't trip the check engine light, so they think when there O2 finally turns it on that it tripped the knock sensor code also. Just go ahead and do it, you will probably find your old one is cracked or melted.

For the 0903, inspect the vacuum-lines and harness going to it, it is a small selenoid valve located on the evap canister, the evap canister is behind the drivers side wheel up near the gas-tank and covered by a square black plastic peice. If you can't find anything wrong with the lines or connectors your next step is to.......

 

thanks a lot KRRZ350 I've got all that info, I'm gonna check it out today, I just borrowed my buddies OBDII code reader, now I'm just looking for the plug> I remember hearing its on the passenger side but I cant find it, unless you need to unplug the harness off the ECM on the passenger side.....
thanks again, I am going to change the KS like I said I was more curious than anything, still wondering if you can check the KS other than the resistance?? I'm trying to find out today while I have the OBDII. I'm gonna go out and try to find the plug in.

 

alright plug in is staring me in the face on the drivers side right under where the fuse panel is. It's showing the KS and EVAP, upon testing the 1st harness off the KS i get .566 with my meter on 2M (ohms). Either way I'm gonna change it, I guess I cant read sensor voltage with this OBD II reader. Its too damn hot to be reaching in to get at the KS today I'm gonna do it at work next week. Is there no better way to test the KS though other than this harness?
