Hey, so I’m buying a Honda tomorrow for a daily driver, and I was test driving it today. I couldn’t get it to rev all the way out and it would only hit 5k before it acted like it was hitting limiter. I was wondering if it was because the engine wasn’t heated up all the way or if it could be something else. I’d love to hear what you guys think, so please let me know, this is my first Honda. I’m usually working on Volkswagens.

 

Don't be in rush to purchase.

Does car have a salvaged title?

Have you checked whether the car has the stock D16y8 engine and P2P ECU?

What CEL codes are stored in the ECU?

Post some pictures.

 

well, the car is stock, and it has a clean title. I’m in a rush to buy the car because other than the fact that it didn’t rev out all the way, it drove perfect and when I scanned the car with a computer nothing came up. There were no lights on either. I’ll try and find a picture of the engine to post on here.

 

Your picture says otherwise. Don't be in a rush to purchase a potential nightmare. Be smart so you don't end up with buyer's regret.

Why do you assume this^ is a small issue?

Details?

Post the head and block codes. Also post a picture of the ECU label.

 

Its in Limp mode..

 

Take it for another test drive with your code reader connected... go into the "Real Time Data" display and find the RPM value. Run the car back up to redline (after you properly warm it up to operating temperature) and see if the code reader shows a RPM value at or near 7000 RPM.

 

do you know how to fix it? It feels like it has all its power, and the car drives fine.

 

I should’ve thought of that. Will do and I’ll tell you the results

 

I don’t think it’s a small issue, but I have extra money, and about a week after I get the car to fix it and everything. Someone said the car was in limp mode. I really shouldn’t have buyers remorse because the car is only 1k and it still runs and drives

 

Take the neg battery terminal off for a few mins and or the ECU or ECU fuse, this should re set the ECU and sometimes clears the limp mode.

 

thank you! I’ll let you know the results tomorrow. Hope this works, I did a little research and now have a few ideas of what it might be. Hope I don’t have to buy a new ECU

 

 

LOL This re sets the ECU!

 

You are a tech idiot. Just stop posting in tech forums.

Do you know what the definition of limp mode is?

 

Yea you fool!,

Also known as ‘limp home mode’, limp mode is a security feature in cars which activates when the engine or transmission control unit picks up a fault. Once it detects a problem, limp mode will cause the less important parts of the car, such as air conditioning, to switch off, and the speed of the car will be reduced. This is to ensure the fault doesn’t cause anything serious to happen and helps the car to ‘limp home’. The limp mode feature is designed to let you know that there are issues occurring with the mechanisms of your car, which could be detrimental and will need to be fixed immediately.

When you reset the ECU it can clear the fault code! I have done it a 1,000 times so stop with your no experience having self! you make your self look even more stupid you Donkey!

Copied from @fcm
At our shop, [Dave Ward Auto Electric] we disconnect the batt. to reset the ECU/ECM, [or any control "module"] for no less then 5 min, on most cars we disconnect both the pos.(+) and neg.(-) terminals and connect the terminals together to insure all cap, [wherever they are] are "drained", then the pos.(+) batt. cable is reconnected, then the neg.(-) batt. cable is reconnected.

This insures all "modules" are reset, there is no assuming. 94

OP read this article don't listen to that clown he has no real world experience!

Hey wunfkngidiot --> Your peanut brain never considered that when you clear hard sensor codes, they return.

 

Hey Mulletfag he doesn't even have a hard sensor code!!!! Tell me what code he posted??? that's how big your peanut brain is lmfao

Again you have no REAL WORLD experience! go back and hit the books son! There has been plenty of times I had a rev cut from limp mode with NO codes shown and re setting the ECU clears the limp mode and the engine revs freely Sometimes the ecu will still store codes and not flash a cel which may be the OP's case..


Here's a perfect example of clearing the limp mode by re setting the ECU,

Hey, wunfkngidiot,

You are the one who called it Limp mode, which only occurs with at least one hard sensor code.

Double knucklehead posts.

 

And I bet your dumb *** it will clear when he re sets the ECU like I mentioned!

Go hit the books son I think its even bed time for you in fact!

 

So, were you wrong that the OP's car was in limp mode, genius?

Waiting eagerly for your genius tech response.

 

No Mulletfag its in limp mode like I said and the ECU probably has the code stored.

But like I said re set the ECU and see what happens OP !

 

Hey wunfkngidiot, your tiny brain is now leading you in circles and causing you to contradict yourself.

Thanks for the evening entertainment.

 

Anytime MulletFag! I think your mom made dinner!, get out the basement and go wash up!

 

Here's a brilliant idea for you. Go clear the non-existent codes from your ECU so that your engine will stop running in limp mode.

 

Well MulletFag if you read this article I posted your peanut brain would of learned something new today,

There are several reasons why you may need to reset your car's Engine Control Unit (ECU). If your fuel economy suddenly declines, resetting the ECU can at least provide a temporary fix. After you install aftermarket parts, resetting the ECU will help your car's computer "learn" and accommodate the new parts. Sometimes a faulty check engine light may appear, so resetting the ECU can make it go away. If any of these problems are affecting your Civic or Accord, it is very simple to reset the ECU. Keep reading and this how to will guide you through the process.


And I guess Tchleung and wantboost are wrong in this post that the ecu will still store codes and not flash a cel…
