P1298 Code For 02 Honda Civic Si

Model: Honda Civic Si Fault Code: P1298 Posted: 2007-05-13 08:31

I am getting this code - P1298 Electrical Load Detector High Input - Has anyone else delt with this before? The load detector is located on the fuse panel. I have read that the fix is to replace the fuse panel including the ELD. Can this also be caused by a short? If so what is the best way to diagnose the short??

Usually what causes this code is a blown fuse from the wiring harness shorted on the underside of the intake manifold. It usually rubs on the brace or the bottom of the intake and shorts out a wire and blows a fuse. Do you have any other codes? If so post them. Check this first and tell us which fuse is blown inthe fuse panel. It'll help find the short.

By the way, Clopticon has to be the coolest name we've had on this forum so far.

Thanks for the info! P1298 is the only code that is returned. I will look at the fuse panel to see if any of them are shorted. I will post what I find. PS. The nme is a play on the Decepticons from the Transformers and my last name.

It thought it sounded awfully "transformer-y" Btw: transformer movie? Coooooooool! But I wonder if that cassette tape Decepticon Laserbeak will be a CD instead?

I visually inspected all of the fuese with the exception of the power windows and all were intact. The windows work so they are intact. Should I take the manifold cover off and inspect the wiring harnesses?

Well, if there were no blown fuses(make sure and check under dash fuse panel and under hood distirbution box if it has one) and the code is still present, then it's not a short in any of the harnesses. The ELD is probably bad. The Electronic Load Detector basically monitors how much current the charging system is using so it knows how much to charge the battery. If there's a short, it creates a HUGE amperage draw and the PCM sets this code. But if you don't have any fuses blown, the ELD is likely the faulty part. It's not an uncommon failure, and there's alot of reports of those going bad. Honda has a TSB out on it and you can buy the ELD separately, but you'll likely have to go to Honda for the part. The first step(checking fuses) may not have helped, but that's the first step to diagnosing the ELD.

Thanks for the all your info! I was really hoping that it was a short but electrically everything seems fine. Everytime I pulled a fuse I kept thinking "Its this one! Nope damn!" I am afraid that its the ELD. Hopefully a new one wont cost me a lot. I will update the post with my findings!

Yeah, feedback on what fixed it helps us know what pattern failures there are. It's a big help and plus, let's us know when we do any good!

I have the P1298 trouble code but my scanner says "fuel air metering". Is this correct or am I looking at a different problem? I will check the fuses first to try to determine the problem. I have a 2002 Honda Civic.

Thanks for the advice, Darkrooms, I have an '02 Civic Si as well and my check engine light just came on last night. The ECU insists on dropping the fuel cutoff to 4,000rpm now, so I'm hoping this is an easy issue to fix. I'm about to run out to check the fuses now, but just thought I would ramble off some info on what codes I'm getting: P1298: Electrical Load Detector Circuit High Input Probably Causes: 1) Open or short circuit condition. 2) Failed ECM. P1259: VTEC System Malfunction Probably Causes: 1) Low oil/pressure. 2) Blocked oil passage. 3) Failed VCT oil control valve.

Just checked all the fuses (both under the steering wheel and in the engine compartment) and I didn't find any blown... any other ideas? I really appreciate the help!

There's an area on the engine, under the intake that the harness likes to rub and short. If you had no blown fuses then That's not likely the problem. ELD failure is a fairly common problem.

Makes sense, is there a way I can inspect the ELD? I'm just coming from a '91 CRX, so I'm not sure what the ELD is, where it's located, or how to check it. I have a DMM that I can check resistance/voltage/current with if that helps. Thanks

I don't know if this is related, but only a week after buying my '02 Si, the passenger-side headlight went out. The same day my check engine light came on, I noticed the driver-side headlight is out. Each light went out only about 2-3 weeks apart... seems odd. Perhaps it's related to the ELD's warning of high voltage input, *shrugs*

The check engine light went out on it's own today, I drove it for another 20 minutes or so after it went off and it never came back on, we'll see how that goes... thanks again for the advice!

Hi, my name is Nic and im going to school for auto technology, I stumbled across your postings and wondered if I may ask a question. I have a 2002 Civic Si, which has the P1298 ELD code and a few other codes. Currently, there is some sort of electrical short or draw that is preventing the brand new alternator from charging the battery. We have replaced the ELD sensor, which some of the students in the school diagnosed, and the car idled fine for close to an hour. Upon the initial test drive however, the battery light came back on. The codes did not return until the engine was placed under load. ANY help or advice that can be given is EXTREMELY appreciated. Thank You

Hello I had a similar problem on my 98 Honda Civic what i found after having diagnostic ran on my car at autozone that my was failing on codes p1298, p0141, p0135, p1456 what i found from searching other forums that a wire harness rubs agianst the back of a metal bracket that hooks to the exhaust manifold and engine block. Looking at the wires you can not see where the wire is damaged without removing the metal bracket. Once i did this one wire had been damaged and shorted out on the bracket causing my computer to throw all four of these codes. I repaired the wire with electrical tape for a quick fix. I also changed the 7.5 amp fuze that was being blown due to the short and reset my computer havent had the problem since. This wire harness is easy to find on 98 civic its located almost directly above the oil filter to the right of the alternator underneath the car you should see a blue plug and the wires coming from this blue plug ride behind a metal bracket wich as stated above are screwed into the back of the exhaust manifold and egine block once you remove the bracket check these wire for any damages im guessing their the same on a 02 civic.
