Help! 95 Lude CEL Woes.
 
Hello, I am a new member today.
I just bought a 95 prelude. Plenty of zip from the 2.3.
The problem is when I drive it 5 miles or so.
The CEL comes on, it seems to run ok with it lit. I can stop, cut the car off and start it up right away and it will stay off for about 5 more miles or so, then there it is again.
I checked the codes , but no blink whatsoever. The light comes on when I hit the switch, then it goes off.
This car has 140000 mile on it, I just don't want to be broke down anywhere, and want the best MPG I can get from this Lude.. Any help would be great. Thanks, Rob. Dealer777 at aol ;)

whats up man, welcome to the site! as for your CEL i dunno what to tell you...im sure one of the guys on the site would be happy to help though.

are you sure your checking the codes correctly?
ANY time the CEL comes on, even for a split second, it stores it so that you can check what it was.

follow this tutorial:

except the picture doesn't show the right connector. its supposed to be a blue connector with 2 pins, not 3.

The plug I was checking had two wires, but it was yellow. Wrong one. After reading your replies, I looked for a blue one and BINGO. Codes 1 and 41. Now to the batcave to figure those out. Thanks for all your help.
Rob.

Well that's good... now you know that the problem lies with your Heated oxygen sensor, and the heated oxygen sensor heater (sounds a bit redundant lol)

So that's what code 1 and 43 is? 1 seems simple, 43 on the other hand I', not so sure about. Is that something that can be done by me?



Now I see I typed 41 in the first post, it showed 43. to much time with my head upside down looking for the plug. LOL

BadMofo 03-20-2008 04:07 PM

I thought you said 1 and 41? And yes, those are what those codes mean... the codes were listed right in that link that twokelv6coupe sent you =P.

It sounds like you just need a new O2 sensor... I'm not really sure about the o2 sensor heater.. but that problem might go away with a new o2 sensor...

Also, you might wanna check to make sure it's actually hooked up and the harness is good.

95 Ludelover 03-20-2008 04:10 PM

Yea, I typed it in wrong. It showed 1 and 43. HO2S and Fuel Supply System, That sounds scary.

95 Ludelover 03-20-2008 04:20 PM

I can't find any info. on the Fuel Supply System. Any idea what I could do about that one?

twokexlv6coupe 03-20-2008 04:28 PM

download the 5th gen service manual located in the FAQ's, and it'll walk you through step-by-step how to diagnose the Fuel Supply System CEL.
its also a GREAT resource to have ANYTIME your having any sort of trouble with your car.

Thanks, That worked. Do you have any idea what to do about the code 43 which is Fuel Supply System?

95 Ludelover 03-20-2008 04:36 PM

I have a 4th gen 95 but haven't found the service manual yet.

twokexlv6coupe 03-20-2008 04:41 PM

im dumb! thought you had a 5g for some reason

its in the 4G resource guide.

95 Ludelover 03-20-2008 04:55 PM

I'm the dumb one. I doun't see anywhere to download the manual at all on this site.

95 Ludelover 03-20-2008 05:10 PM

Great, I have found it and downloaded it.

twokexlv6coupe 03-20-2008 05:15 PM

good. now save that sucker to your desktop, cherish it w/ all your life, and refer to it anytime your havign car troubles, then after you searched it good, then you can make a thread here :smile:

95 Ludelover 03-20-2008 05:27 PM

Thanks, I am going to try to find the fuel system in here. I will hang on to this manual for sure. Ya'll have been a great help. I look forward to being able to help others myself soon.
