2 questions??
ok first question is...the oem plug that comes in the 4th gen max is that the pfr5g-11 plug the platinum?? and 2 when u install a new camshaft position sensor do u just unbolt the old one and slide the new one in and bolt it back up or is there sumthing u have to do?? cause i keep getting a check engine light for camshaft position sensor circut malfunction..i dont get it its a brand new cps sensor

On a side note, I assume you reset and cleared your code for the hell of it, and it came back right away?
Oh, and here's the obligatory link we've given YOU a million times now.

there isn't more thsan one. there are two ckp (crank position sensors) (one CKP and one CKP Ref (refferance). The CPS (camshaft position sensor) is just a bolt on, no adjusting needed.
It's probably not your CPS tripping the cel, I bet it's your KS. Sometimes the KS will trip the cel, sometimes not. The CPS and KS are linked, like the 2 CKP sensors. Maxima's btw are the only V6 from Nissan with a Ref CKP .... lol Go figure! lol
Are you reading the codes yourself, or haveing them read? What codes are you getting? Post them plz.

im reading the codes myself...idk the numbers for the code but its camshaft position sensor circuit malfunction....and my car has been runnin crappy latly idk what it is..maybe it is the knock sensor how do u know if ur car is running in safe mode??

safe mode for the ECU? It's not .... or you would you would know it - stuff wouldn't work.
Take your car to Autozone and let them pull the codes, LOOK at the OBDii reader and write down the codes. You're not going to get far by not knowing what codes you are pulling. Common sense here, right?

Ok smartass ... you're on your own now.
I asked you what code it was, you told me you don't know, so .... have fun. It's a P xxxx code, if you don't get that, you just don't understand.

huh ... I thought that the KS retards timing, and the CPS advances timing? Perhaps not then ... I stand corrected. As for the KS not tripping the cel, it does on Infinity (QX4) anyway. I understand that they both feed info to the ECU, but then what is the prupose of the CPS if not timing related? As for the KS, I know it works on a pizo electric / magnetic basis and denotes detonation ... I thought it related to timing as well. Doesn't it?
edit: The KS on the Infin tripped a P0325 code and a P0300 (random misfire) code as well ... so perhaps the P0325 tripped the CEL, and not the KS. Why doesn't the KS trip the CEL anyway? I know that a bad KS will make for a rough idle and hard starts.

On the A32 ECU, the KS will not list the CEL. The CPS doesn't advance anything, all it does is relay data about cam position, same as both CKPS just relay data about the crank position. The KS doesn't retard timing per se, but as the ECU tries to advance timing, if the KS detects knock the ECU will pull back to a lower timing value (as I understand it). If the KS isn't there or is just plain faulty, IIRC the ECU just goes to a hard-coded (and conservative) timing map.

The reason people think the KS code is related to other codes is because it is a ghost code. They get a code that trips the CEL, scan the codes, and they also have a KS code that had been there for a long time just never new it.
:sprint to knowing which code it is, as has already been stated there are 2 crank and one cam sensors.
There is however another cause that can trigger any of the 3, and that is a problem in the starting system. Only if your car doesn't want to crank properly and trips one of the cps codes occasionally, should you worry about ignoring it. If youre car doesn't want to start, or dies, and consistently trips one of the cps codes you should look into the wiring, sensor, and trigger wheel of that particular cps code. If it's the REF sensor on the crankpulley for example you could have a really deteriorated crank pulley ready to go at any second, or oil from a leaking pressure switch could have contaminated stuff. Just trying to give specific examples of how a code does not mean replace the sensor. This even holds true with the KS, I've been guilty of replacing good ones during the summer months not knowing the owner was running regular fuel.

so, what is the 'start' issue that can cause a CEL trip? I understand that the KS will not trip the CEL so I'd say if it is tripped, there are other reasons. (at least on the A32 
)
