CEL problems

Ok guys. My check engine light has came on recently and im wanting 2 get it fixed withought having 2 fix a million different things 2 find out whats actually wrong with it. Alright i'll try 2 give as much info as possible. Its a 98 base with 114k on it. Also its automatic. The light came on a lil while ago and i took it 2 auto zone 2 have the codes brought up. Alot of different stuff popped up. Some had 2 do with a faulty auto tranny, failed gear selection switch, and poor electrical connection. But my tranny is shifting fine. No problems with it at all. Im hoping its not that. Also other codes were...A/F ratio concern, air leak near heated oxygen sensor...? ignition system concern, faulty catalytic converter. Blocked oil passage, vtec pressure switch fault, vtec solenoid fault amd faulty A/F sensor. Something i have noticed is if my car sits for a lil bit, white smoke will start coming out of the exhaust. Sometimes it will happen after 5 minutes, sometimes 15 mins. Can this be a reason why the cel is on? I really need help and i will greatly appreciate anybody who takes their time 2 read this and give any input.

Re: CEL problems

F/A is the rear o2 sensor check that out, that might fix some of the others as well, and go back to autozone and see if they have i forgot the name but to flush and clean you oil and read the can it comes in for direction, maybe others will pop in and help you i not for sure about some of the other things, my o2 sensor went out 2 months ago and the code said F/A ratio i changed it and went away

Re: CEL problems

Well my check engine light was on before and the 02 sensor came up so i bought one and my dad changed it out. It was one that had 2 have the wires spliced and all that. But im not entirely positive he did it rite. I would love if he just messed it up and did it wrong. I'll have that checked out. And are u talking about seafoam? Thank u for ur reply

Re: CEL problems

the vtec is related to oil pressure check for any oil leaks around the engine,common leak areas are the vtec solenoid upper and lower gaskets, cam plug, distributor and valve cover. Also make sure its not running too low on oil, you would need to be down at least 2-3 quarts for that to effect vtec tho.

for the oil passage id try sea foam.

put 1\3 in the intake, pour it into the brake booster line running into the intake while the engine is idling you have to pour it slow or it will stall out.

once u pour the 1\3 in the intake let it sit for 10-15 min then rev the engine till the white smoke from the exhaust is gone DONT DRIVE IT till the white smoke from its gone.

once its gone turn off the car pour another 1\3 of the can in the oil and another 1\3 in the gas tank.

drive the car no more than 15 miles then change the oil. You must change it after 15 miles or it can damage the engine because of how it effects the oil.

you must also change the oil 1500 miles after to get any remaining sea foam out of the system.

if you need a pic of the booster line let me know.

ive used seafoam exactly like that on my 01 accord and my 01 prelude with good results.

and the white smoke from the tail pipe is from 2 things piston rings or valve seals. its hard to know which it is for sure with out taking the engine apart.

if its the valve seals you can get this stuff called white shepard off the internet (google it) runs like 15 a bottle and works miracles on that stuff but wont help piston rings.

the air leak might be from a bad exhaust gasket.

id also double check the codes you got.

get the code numbers and post em.

Re: CEL problems

i would say sell that lude. and get one that is a manual 5spd. if this costs a lot to repair all that. i mean CEL's usually throw mult codes for just one issue. but those are crazy!

i mean o2 sensor is understandable. but those other are just strange.

those auto-stick tranny's are garbage. so if thats ur issue, i would try and find a 5spd if that an option. only cuase those are well worth the investment, and time and you wont have those transmission issues. good luck!

Re: CEL problems

Sounds like an AWFUL lot of codes... Maybe your ECU is bad?

Post up all the actual codes in here... not just what they mean, but the actual P##### codes...

Also, post them as a list like this:
P####
P####
P####
P####

It'll make it much easier for us to read. It's hard to read one continuous free flowing paragraph like that.

Re: CEL problems

Ok. Thanks for everybody with they're reply. First thing, I would sell the lude and get a 5spd but im actually still making payments on it. =/ Also "untothecruel" it would help alot if i can see a pic of the booster line and where its at. Thanks for helping me out. I dont know much about cars. Im just trying 2 learn. And "badmofo" i have the codes. Here they are

P1259
P0700
P1705
P0133
P0420

Im really hoping its not a big problem. I need 2 get tags for it in november. Once i pay this car off im planning on gettin a 5spd. But again, thanks for everybody's help

Re: CEL problems

P1259 is a vtec pressure valve problem
P0700 is indeed automatic transaxle
P1705 is also automatic transaxle
P0133 is Primary (front) oxygen sensor
P0420 is "catalyst system"

Ok, here are my guesses...

The automatic transaxle, I don't know much about since I drive a 5 spd... I would suggest you check the fluid level in there, and any and all sensors that are hooked up to it. Make sure there are no missing or damaged sensors/wires/plugs.

Vtec pressure valve, try removing and cleaning your vtec solenoid and cleaning/replacing the gasket and screen for it. There are tons of writeups on how to do this if you search around, also the helms manual comes in handy for it (you can download the helms manual for free from the "5th gen resource guide" thread on this forum).

And the primary oxygen sensor you can replace for fairly cheap. I suggest either a Denso or an NGK (NTK) direct fit replacement. I got my denso direct fit replacement for 40 bucks and no splicing is required. DON'T GET A BOSCH... from what i understand they throw codes right out of the box.

I'm willing to bet that the "catalyst system" error code is directly related to the primary O2 sensor code... Just for good measure though, while you are under the car replacing your O2 sensor, bang on the catalytic converter a bit and see if it sounds like there is anything rattling around in there. If it sounds like there is stuff rattling around in there (it sounds kinda like sand on metal) it means your catalytic converter is definitely shot. If not though, the code may go away once you replace the primary O2 sensor.... You might wanna replace the secondary O2 sensor as well while you are under there..

It also is a good time to make some minor tune up type repairs. Oil change, new air filter, new spark plugs, wires, distributor cap and rotor, and clean your EGR valve/ports. If after all that, the "catalyst system" code is still coming back, it's time to replace your catalytic converter...

After you make these repairs, reset your ECU and see if the same codes come back, and then go from there.

Re: CEL problems

Ok thanks alot. For the denso o2 sensor, where were u able 2 get that at for that cheap? I'll try all the other stuff. And for that seafoam trick, does it matter how much gas i have in the tank 2 do it? Hopefully "untothecruel" will be able 2 post a pic of the booster line. Thanks again for everybodys help. I really really appreciate it

Re: CEL problems

Honestly, I don't really remember... but I think it was Rock Auto...
www.rockauto.com

Edit: Yep, just checked and it was indeed rockauto under emissions -> Oxygen Sensor


It should be the first one, Denso #2344092

I believe that the denso one will fit either the front or the back, so it has a long cord on it... make sure you do a good job of keeping the cord for the front one away from anything hot or moving.

Re: CEL problems

i dont think how much gas is in the car when you add the sea foam matters.

booster line is circled in red. when you remove it from the firewall car will idle funny thats normal. when you pour u gotta go super slow or the car will stall out. you will be able to hear it hesitate before it stalls

Re: CEL problems

Thanks guys. I appreciate it more than u know. I will try 2 replace both o2 sensors cos the rear is actually a bosch one. Lol. And then i'll try fixing everything else. Hopefully I can fix this thing!! Oh and one last thing. If it is my auto transaxle, then what would I need 2 do 2 fix that? I promise thats the last thing! Lol thanks badmofo and untothecruel

Re: CEL problems

Well if it's the transmission you should take it to a reputable mechanic, transmission shop, or a dealer to at least diagnose the problem...

Hope everything works for ya bro, keep us updated.
