are all the trubble codes the same for all cars i pulled the codes myself and i got an 0706 and an 0304 the link on the org says they are undefined...i got those 2 in my girlfriends 95 altima write back if u have any info for me thanks guys

 

Trouble.
--------------

 

any idea what these codes mean?

 

I don't know what it is but 0304 is not undefined. Someone should know that one.

 

You try the stickies?

 

So... are Alimta trubble codes the same as maxima trubble codes?

Maybe you should look closer into an altima site...

Anyone see that hubble telescope?

 

if the codes are the same for maxima and altima, 0304 = Knock Sensor ( indicated in the stickies)
but 0706.. no clue..

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 12mm ratcheting box wrench could replace the KS without disturbing the manifold.

Important note: the dealer can do a more thorough test with his CONSULT electronic tester. The resistance test described here is a useful but limited test. A Knock Sensor which fails this test is definitely bad. However, a KS which passes this test is not guaranteed to be good.

 

Why would I try the stickies?

My car is codeless.

I was thinking knock but I have never had it and rather than guess I figured someone would have it, I knew it wasn't undefined.

Don't judge me!

 

Oops, I replyed to the wrong post. D'oh!

 

Anyone notice it was for an Altima? ..

 

Sentras share some similar codes...

 

404 ERROR KA Altimas and SR Sentra cylinder banks not found.


I'm just being semi combative to the who cannot read the stickys... that's all... And that cut and paste patna over there pasted some semi useless info due to the fact that....well, read my 1st sentence up there...

 

Well, if you read my post correctly,
That's why I wrote this first:
if the codes are the same for maxima and altima, 0304 = Knock Sensor ( indicated in the stickies)
but 0706.. no clue..


I only copy/pasted that info in hopes perhaps the Altima shares the same set up as the Maxima in hopes to assist ARN1CK better in regards to replacing the KS.
