I'm trying to smog my 1997 honda civic lx, I've been through 2 or 3 drive cycles and my monitors arent resetting. My ecu is a p2e-l31 and I know usually it's an l32 that comes stock I think. So either maybe it's my ecu that's the wrong one or my ecu resets whenever I turn off the car

 

Post all CEL codes that return after resetting the ECU and driving the car.

Post the most recent smog emissions report.

 

There was a dx racing exhaust with headers before with no cat or 02s so it immediately failed, and it throws p1298 the eld fuze I replaced it tho and all the wires from it look fine
I have the cat and 02s on it now tho and still they wont set

 

L31 vs L32 is not likely to be your issue. Make note of it and move on.

Your car should have a "DX" exhaust on it with the combined manifold/catalyst. and the O2 sensors mounted before & after. You won't be passing smog any other way.

Do you mean a P1298? There is no readiness monitor for the ELD circuit, fix your issue there, do a drive cycle and that will be fine.

 

Your car will never pass smog with a bad cat, missing O2 sensor, and ELD code.

 

The cat and 02 are brand new, just put on by a shop 100miles ago, I replaced my eld in the fuze box and still nothing

 

There is no CEL on, but whenever I plug in the scanner it throws that code. I've erased it and drove through the cycle a few times now

 

Will having the code make it where my monitors arent resetting? Maybe it's a bad wire

 

What you are saying is that the ECU is still throwing codes. Are you see the original codes, a subset, or new ones?

FYI - The ELD code did not tell you to replace the ELD sensor. It told you to troubleshoot the ELD circuit to pinpoint the specific problem.

 

It just keeps showing the P1298 code that's it

 

Just eld circuit high input, a diagram for this would be nice to know what I'm looking for

 

From what I can see my wires look fine

 

Is it a pending code or a permanent code?

Every time you clear codes you reset all of the readiness monitors, and then you have to go through the full drive cycle to get back to readiness.

 

Does the charging system light in the cluster work?

 

actually the cel was removed when I got the car along with a few other bulbs but I replaced the cel bulb so I know it doesnt come on. I didn't see a charging cluster light in there

 

it says its saved in the ecu and it's been a couple weeks since I erased the code I've just left it alone. I'm taking it to a shop tomorrow to diagnose it so I can fix it

 

Turn key to the ON(II) position without starting the engine. Is one of the lights that turns on and stays on in the cluster the charging system warning light (battery symbol)?

 

So if your CEL doesn't work you aren't passing step 1 of any smog check. You need to start there.

 

cel lights up when i turn the key to accessory. i dont see a battery light though, what does that mean?

 

Possibly a bulb out, if you never see it come on at all. Not a smog inspection issue so no worries.

 

Check whether dash fuse 15 is blown. If fuse 15 is blown, search for the fuse 15 Honda TSB, which is a problem with wires shorted to ground on the rear of the intake manifold. Also replace the fuse to see if it blows again.

The fuse 15 problem can cause CEL code P1298 (ELD) and O2 sensor codes, among others.

 

fuze 15 hasn't popped

 

Could somebody send a link for the drive cycle on a 1997 civic lx, d16y7

 

Your post mentioning that the cluster warning light for the charging system does not work is consistent with a blown 7.5A fuse 15 but is not proof.

Given the additional link of O2 sensor and ELD CEL codes to the Honda fuse 15 TSB (link below), you should consider checking whether both test tabs of fuse 15 have battery voltage with the key in ON(II). It's an easy verification test.

Do voltage tests using a multimeter on the hood 7.5A BackUp fuse 47. If this fuse is blown or removed, the ECU will not be able to store drive-cycle information.
