I changed my clutch out this weekend and know I have a
a 3,4 knock sensor code and a 9,5 crankshaft sensor (postion)
the car runs bad at 3500-4000 rpms it kinda gives out and jumps
what can I do to fix it has anyone else had this problem
help

 

DTC 0304
Diagnostic Trouble Code 0304 points to a problem with the Knock Sensor. The KS is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is senses as vibrational pressure. This pressure is converted into a voltage signal and sent to the Engine Control Module (The computer).

This malfunction is detected when an excessively high or low voltage from the KS is entered to the ECM. Possible causes include...
- the harness or connector (The KS circuit is open or shorted).
- the KS

The KS may be checked with an ohmmeter.

1) Raise the hood. View the engine from the driver's fender. Look into
the deep valley between the cylinder banks and below the intake manifold.
Identify the KS as a black item fastened to the block by a single vertical
bolt. A wire harness wrapped in black leads toward you, out of the valley.
That is the KS sub-harness.

2) Follow the KS sub-harness to it's nearest connector. This is connector F121.
It is located near the upper right-hand corner of the valve cover of the forward cylinder bank, as viewed from the front of the car.

3) Disconnect F121. You have to do a "press the latch and wiggle and
pull" to disconnect it. F121 has only two pins; if you see more than two
pins, you have the wrong connector. Use a digital ohmmeter capable of
measuring more than 10 Megohms. You want to measure the pins of F121, not
the sockets of the matching connector. Measure the resistance between a
good ground (such as the battery negative terminal) and pin #2 of connector
F121. On my car this is the highest of the two pins, the one closest to
the front of the car. The factory spec is 500 - 620 Kohms.

The manual says you have to remove the intake manifold to replace the KS. However, I think that a person with good dexterity and a 10mm ratcheting box wrench could replace the KS without disturbing the manifold.

 

well what about the crankshaft sensor ( position)
you cant cut and paste that from another thread
if any has any ideas how to fix are trouble shoot problem
please post IF YOU ARE POSTING JUST TO POST DONT BEACAUSE IT
IS SAD AND YOU ARE THE ONE THAT IS MAKING THIS A CRAP SITE

 

I thought MedicSonic's post was relevant.

 

Screw it then, no info on the other one then...

 

Don't do that Medic... please continue to help ungrateful members who can't look up the sticky threads or don't know how to use the search.

 

screw you you guys dont know anything I had to ask
somewhere else, you guys say you are maxima guys but really
only repeat what other maxima people have said.
get mad I dont care only a hand full of you guys are even
worth a ****.

oh and please email me if you have anything futher to say
since this thread is not for me and you to fight on

 

WOW, what to say. Hey Mark, where did you get your clutch installed? I live in Md. and am going to need my ACT II put in as soon as it gets here.

 

I actually gave him a straight answer and he still doesn't like it.

 

your starting to lose your AMOC, whats goin on ??

 

What's AMOC stand for?

 

November was 'Let's be nice to everyone' month, thank god its over in 4 days. And if you don't kno what AMOC is, you aren't in...
