I took my civic to get emissions and it failed the Hydrocarbons test and the Carbon monoxide test. My CO % Read at 9.19 and it has to be 0.94 or under and my HC ppm read a 298 and it has to be 167 or under. I have reset the timing and replaced the spark plugs adjusted the valve lash. i have no idea on what else i can do. i know there is something wrong cause the CEL is on but when i try to jump it off the SRS blinks and the CEL stays steady.

 

When the key is turned to ON(II) (engine not running), does the CEL remain on steady without the service connector jumped? Or does the CEL turn off after 2 seconds?

Have you also replaced the plug wires, cap, and rotor?

(The blinking SRS light indicates a problem with the airbag system)

 

O2 sensor may be stuck... Need to do pinpoint testing at the sensor connector.

 

the cel goes off with out the jumper in it, but once the car is cranked it comes back on. But i just fount this out today i have the p06 non-vtec ecu and i need the p08 vtec jdm ecu. i have just ordered one of those and i hope it will fix it. cause the car runs like crap.

 

just bought a new 02 and it didnt fix it.

 

That would be a good start...

 

i heard that a p06 has the wrong idle and compression settings and it will never work with my jdm d15b vtec

 

that is correct.

 

You definitely need the proper ECU.

Nonetheless, here is how to pull the CEL code(s):
The next time the CEL turns on while driving, pull over and leave the engine running. Then jump the service connector.

 

I got 8 quick flashes which is Code 8 TDC position

 

im gona yank out that sensor right now!

 

Check whether the TDC sensor has 350-700 Ohms of resistance.








If the resistance of the TDC sensor is fine, check the TDC wires for a short or open.

 

where is that sensor located at?

 

It's inside the distributor.

Just measure resistance across terminals C and G of the distributor plug (not the wire harness plug).

 

someone just said its located by the timing belt? http://www.google.com/imgres?imgurl=...26tbs%3Disch:1

 

No, that's an 01 Civic (7th generation). You have a 5th generation Civic.

 

its bad... how do i take it out?

 

You generally must replace the entire distributor housing when any of the distributor sensors are bad.

If you can find a TDC sensor (resistor), it is possible to remove the bad one and solder in the new one, but most people don't do this.

 

so i need a new dizzy?

 

(is admiring the amount of awesomeness this thread is going through)

 

on 2nd note everything is fine with the dizzy, so it has to be the ECU Ordering a P08 now.

 

I had that damm cel 8 forever and I new my dizzy was good so I never replaced it. I later found out that one of the pins was slightly depinned so it was not making a good connection. So if you know your dizzy is good, I would make sure that it plugs in nice and tight and when you look at the plug you can see all the pins.
