I am getting a 0201 CEL and I checked the resistance in the coil packs and they seemed to be fine. Is this sometimes not a sure fire method? The car is a 95 and has 140k on it. I myself have never replaced the packs. Are the 95's known for coil pack problems? Any other ideas? Thanks.

reset the code, and see if it comes back. if it does then its time for you to get new ones. my coil packs went out at 110,000

Ok. By resetting you mean clearing the check engine light or do you mean resetting the computer by removing the negative and steeping on the brake to drain everything.

clear the check engine light and see if it comes back. is this the only code your getting did you check for knock sensor code?

This is not related to a knock sensor.

Reset CEL, (follow instructions from Stick's) see if it comes back.

You should check your spark plugs, the 95 dont really have problems with coils packs, but with 110,000 it might just have failed. Check your coils with an multi-meter, they should read infinit ohms.

I am getting a knock sensor code also. The car actually has 140k miles. I did check the coils and I think I did it the right way. They all seemed to read .6 I think.

duh! the ks can trigger the coilpack code if the timing is turned back from the ks

i believe if you change your knock sensor it should go away. maybe you punched the car and the ks retarded the timing causing your coil sensor to activate.

I was driving on the interstate and at first it seemed to get 0604 code. Then I pulled that code and unplugged the coil pack and it seemed run worse, so I plugged it back in. Then I checked the codes and saw the 0304 code and the 0201 code. Like I said the ks didn't read any resistance. I switched the coil pack from the 5th cylinder to the 1st to see if I get another code. I think I will start with the ks though, since I am pretty sure that it is bad. Thanks everyone.

adithius

Whatever dude. I had 0201 changed the coil and the problem went away. I speak from experience.

adithius

You have two separate problems.Change them both since you have both codes. Your multi-meter should read 1(infinite) for the coils.

When you get 0201, usually you get an other code like 0605 (cylinder 5 misfire). Did you get one?

I got one and I changed that single coil. 1000 miles later, and no problems.

Also do you use premium gas?

i never said you were wrong i said there are other possiblities not just what you see. did you know for ex that any code will trip the ks vise versa. after owning 7 maxima since 1986 and rebuilding 3 motors with boost and nitrous dont you think i have some knowledge also about our motors and codes and why they happen? dont make the man waist money for nothing.

krue92

I did have the 0604 code. Then I unplugged the coil pack and plugged it back in. Now I am getting 0304 code and the 0201 code. When I unplug any of my coils on my engine it does make it run worse, so you would think it would stay the same. I don't usually use premium gas. I have 90 octane in it right now.

krue92

Also I just did a clutch in the car and now it is idling rough or maybe its a vibration. It happens at around 1k rpm. I don't know if it something do to the clutch or something to do with the code I am now getting. Would a bad ks make your car idle like crap?

C MAX

90 octane is kind of low for our cars that could also make you throw that code too much pinging and detonation going on probably when you get aggressive. well if you have the knock code that could be from running low octane also. i would try a fuel additive and a high premiun gas, reset the codes and see what comes back and take it from there.

krue92

Well I wasn't getting any resistance on the ks, so I kinda figured that it was bad. Plus the car has 140k miles and I don't think its ever been changed.

PAREDLINE

Sometimes I wonder if people know what they are talking about.

Your engine probably missed ONCE. Sporadically. The light was triggered. Now it is on but your coil packs are good.

If the human heart can skip a beat once in a while, a coil pack is allowed to as well.

Its not your knock sensor. Your timing would never be retarded so far that it would cause a miss.

Just do as the intelligent people say. If the car is running fine, reset the check engine light (clear the codes) and see if it comes back.

IF YOU DO NOT KNOW WHAT YOU ARE TALKING ABOUT DO NOT POST!!! PEOPLE COME HERE FOR HELP NOT TO GET SENT ON A WILD GOOSE CHASE.

sheesh

ALL THE CRAP YOU JUST SAID DID NOTHING TO HELP THE MAN

krue92

I got home from work and decided to check the codes. The only code I am getting now is the 0304 code. Maybe the wire was loose on one of the coil packs and when I snapped it back in maybe that fixed that code. Will having a bad ks make the car run bad?

C MAX

iTrader: (4)

change your knock sensor it should solve your problems. having a bad ks will cause you to burn a lot of gas and effect your performance it can also trigger other codes. end of story.

krue92

I am going to change it out. But its wierd ever since I have changed my clutch my car runs like crap. Its like a vibration at 1k rpms. I did everything to specs, so that is another problem I am trying to solve. I didn't know if something is out of balance or if the ks could make the car idle rough. Thanks.

this seems to be a issue a lot. i would try and ground the tranny with some extra ground wires. i seem to find that when you break the tranny from the motor it sometimes doesnt ground back correctly. i also caught a rough idle and nissan told me this happened sometimes. after grounding my tranny it stopped. i dont know if this would work for you but its worth a shot as far as a rough idle. as far as vibration could be your flywheel. did you resurface it?

krue92

Yes I did resurface it. The guy who did it, has been doing it for 20 years. I would hope he knows what he is doing.
