Ok I am driving a bone stock 2000 si and i know this is a wide range question. but i was driving my car to work today and my check engine light came on, my motor isn't making any weird noises nor is the car acting up. so what can be the cause of this? cause i really dont wanna take it to the honda dealership and let them do something simple and charge me 500 dollars. but if there are any easy solutions to some others problems let me know the car has 75k miles. thanks

take it 2 an autozone get them 2 check it for ya or get ron jowarski 2 check your check engine light for free at double a *toot toot* mco which means act like its ur tranny they should at least give ya the code

soslodelsol

as long as its not flashing then your cats will be ok. if it is then take it to an authorized dealership or reputable shop

B18Sleeper

ok so as long as it just stays on steady and doesn't flash i can drive it until i get to a autozone or something like that? thanks

Are you guys kidding me? Check it yourself. Look up in the FAQs for a how to. PM me with questions, I just went through this.

Try this first and see what the result is. You should be able to diagnose it this way yourself.

in the FAQ's its all about replacing parts, ECU codes, and swaps, but my motor is stock and i have done nothing to it. the only thing i have noticed in the past day is that when it sits for an hour or so and i start it, it will jump to about 1.5k idle and after i drive it for 10 minutes it will drop back to around 700rpms. so how can i diagnosis this myself from FAQ's?

my idling problem can be cause i need new spark plugs but i dont think that would throw the check engine light would it?

Lee_Delso

Honestly our just going to have to do the process of elimation....actually why don't you just find out what code(s) it's throwing?

Well you didnt look hard enough. So go to your car open up the passenger side door. Get on the ground and look up into right side of the kick panel. Take off the panel that covers your ECU. You should see a lil connecter with a lil plug that goes into it. The plug will have two wires connected to it. Pull the connector out and jump the plug with a small paper clip. Then turn your key to the on positon and wala you will get your code.

B18Sleeper

wala where do i get my code? where does it show up?

.Ry

oh lol once you have the plug jumped and you turn the key to ON, the the CEL should flash for ya. Then to read it you can use this..... flash flash flash flash flash = code 20 the longer spaced flashes are the first part of the number and the shorter means the second part so two long flashes mean 2 and three short flashes means 3 so 23. here https://honda-tech.com/zerothread?id=682412

ok did it and i got 4 codes. TPS, Electrical Load Detector, and primary and secondary o2 sensor. how can i fix these and which should i worry about? thanks

B18Sleeper

ok just to make sure i did it right it flashed quick 7 times, then paused, then 2 long flashes, paused then 4 long flashes and 1 quick one, then paused again then 6 long flashes and 5 quick ones then paused and repeated from 7 quick flashes. so is this...codes
7 TPS
20 Electrical Load Detector
41 O2 Primary Sensor
65 O2 Secondary Sensor

you know that one thing honda does now-a-days is when you use other fluids (i.e. oil, tranny fluid, etc...) typically the ecu recognizes that it hasnt been changed by "Honda", then the check engine light comes on till you do something to reset the ecu. It happened in my dad's brand new 03 civic ex.

SigmaOmega

basically they want more business, but yea check everything before thinking that its just a false alarm.

B18Sleeper

yea i changed my oil 2k miles ago, it would be a little late for that. and plus with this jumper test i came out with 7 20 41 and 65 which none have to do with fluids.

First reset the ECU, unhook the battery and wait, or take out the radio back up fuse. Drive it around and see if it comes back on. It may take awhile for it to come back on. I would hope most of those are stored codes. I take it you do not have a Helms?

B18Sleeper

can i fix these codes myself or not? cause trully i dont think o2 sensors will hurt me much besides in gas mileage. but what about tps and eletrical load detector? help please

SigmaOmega

yea something is triggering that light to come on

OMG your so smart, i just thought it came on for the hell of it. i know why the damn light is coming on, i just wanna know how to fix the problems. so please stop adding to this with stuff i already know.

.Ry

Well your O2 sensors can go bad, but at the same time? Same as the TPS, I think they were stored codes, but im not sure which ones. My freind has my helms right now or I would be lookin at it for you.

B18Sleeper

what about the electrical detector load? cause all this came on yesterday, so i ahve no idea.

B18Sleeper

i was told that i need a new TB and Fuse box. is this true?

B18Sleeper

i know the TPS isn't the same as the MAP sensor so what would i need to fix this?
