Hey guys, I pulled the codes from my ecu 2day and these are wat i got from my laptop:
P0325: Knock sensor circuit (bank 1 or single sensor)
P0139: O2 sensor circuit slow response ( bank 1, sensor 2)
P0138: O2 sensor circuit high voltage ( bank 1, sensor 2)

Now my question is wat in the world does this mean? I only though i had one o2 sensor on each bank and then one behind the cat, so which one is bank 1 sensor 2? also my friend told me that my o2 sensor is probally dead but we weren't sure so i figured that maybe somebody here would have more info on this. Lastly since i have a knock sensor code does that mean i need to replace my knock sensor also?
Thanks,
Will

 

Sometimes one bad Sensor could cause another sensor to go off. And can you tell me what program and cable u use to get the code's with your laptop?

 

im not sure of the program cause it's wasn't mine. My friend bought it for his m3 and it works on all obd2 cars. does anybody have any ideas on the knock sensor issue?

 

Does your car engine make a Knocking sound when its running?

 

How did you pull the codes out? did you do it by yourself by counting the "pulses"? I went to AutoZone and got them read for FREE..

 

nah my friends has a obd2 cable and a program that he bought that he uses to pull the codes peoples cars

 

its much easier to just manually pull the codes from the ecu and counting the pulses. but i heard that bad o2 sensors make the ks code go off as well (sometimes).

 

how is counting the pulses easier then just plugging in a cable and hitting run? also with his program i could check like 30 other things that counting the pulses can't let me do. Plus wit the ability to save the codes and record info from different sensors on the car( like max and min rpm's during a trip) makes it alot of fun. I was just wondering about the knock sensor and if anybody knows which o2 sensor has gone bad on my car that would give me the bank sensor 2 code

 

It is DEFINETELY NOT easier to manually pull the codes yourself.

 

So you need to check your ecu codes even when the CEL isn't on? I figure a bunch of us are overdue (or soon will be) to replace our O2 sensors and knock sensor, since those seem to go on pretty much every Maxima at some point, so I'm trying to work out a group deal on them.

 

you do that, budha...you are the gd god!!!

 

Stop calling me a god. I'm just a kid trying to help us .orgers, including me, get the best deal. haha. If you want to know who to worship check out that Passion of the Christ moving. It's absolutely amazing.

 

hey budha if you could set up a group deal on all the o2 sensors and maybe some knock sensors also me and my car will bow to you
