p0301 and p0325 - Altima Forums.net - The Nissan Altima Enthusiast Talk and Discussion Forums

Hello,

I need some help. I am trying to replace all ignition components because I have a trouble code of P0301 and P0325. From what I have been hearing, if I fixed the P0301 problem then more than likely it will fix the knock sensor also. I have changed the valve cover gasket and put new spark plugs (NKG), wires, cap and rotor button. Reset computer and light came back on. Now I want to change the ignition coil and distributor. Now I have the Chilton’s book for my 97 Nissan Altima. It tells me that the coil should be to the right of the distributor for 1993 – 2001 models. It is not there. I don’t know where it could be located. I was wondering would any one else know. Is it inside the distributor? Is it located someplace else? Please help.

It is a 97 Nissan Altima LE with 234723 miles on it. Its an automatic.

Was this resolved? My GF has the same codes.

I will give the advice I have given a few times over the last week. Take the ignition coil for cylinder # 1 and move it to another cylinder and see if the code follows. P0301 is cylinder 1 misfire, p0302 is cylinder 2, etc... If it follows then you know it's an ignition coil.

The 97 altimas have distributors instead of coils. I changed the spark plugs and cleared the codes. I drove around for a bit and turned the car off and on several times and i didn't get a CEL. Thanks for the help anyway.

A little rearch shows it could also be a crank sensor, but hopefully you have it sorted out.

The car will only have one distributor. Common diagnosis procedure is to mix up the coils to have the code follow the bad coil. Hopefully the plugs take care of your issue though.

This looks like a very informative article that can be used my sentra as well. Thanks for the help again.

The check engine light came back. So far i tested the plugs and the wires. I can't test the distributor with the spark plug tester that i have. Is there any chance that it could really be a faulty knock sensor?

**mikejamesbyma** · 03-01-2011

Could very well be. If you are going to cover all the "easy" things first, this is porbably one of those.

FUBAR1O2 · 03-05-2011

I changed spark plug wires, distributor cap and rotor. So far no codes are showing up, but when i plug in the hand scanner it detects knock sensor.

**mikejamesbyma** · 03-07-2011

It's worth a shot, I think. The sensor is around $100, so not a huge investment.

FUBAR1O2 · 03-07-2011

Is this a bad idea?

Lol, $19 you can't really go wrong. I've never heard of Chandler and I highly doubt they are the manufacturer of the part, but again, for $19, why not?

Check #1 injector with an ohm meter. They should ohm between 11 - 14 ohms.
