when i am shifting from 2-3rd and higher, i cant seem to accelerate beyond 5500 rpm. does this happen to anyone? it seems like as soon as the VTEC kicks in at 4800, the ECU is cutting off the power and limiting ll revs from 2nd gear and beyond to 5500 rpm and goes no further. is there anyone in here that can give me an input on whether this is normal????

by the way, this seems to have been happening ever since the A1 service. at first i thought it was the octane being 91 so i tried 93 and still had the same results. does anyone know if this rev limiting at 5500 rpm is normal or could it be possible that the service dept., decided that i dont need to rev more than 5500 anymore? i will really appreciate your help in this. thanks a bunch.

I am assuming automatic here??? If so I cannot comment (6MT). But just in case I have no issue hitting 6800!

I have the AT and have no problem pushing it to 6800. But when I do the ECU cuts off and starts sputtering. I would take it in and have it checked if it is doing that to you.

Using 91 or higher octane, you should be able to achieve 6,800 rpm in any gear, at which time the rev limiter will cut in. 5AT and 6MT are the same, it is the engine that is governed, not the transmission.

If you are sure the gas is actually the octane specified, which if you tried two different octanes (from different stations, I hope) it should be good, then you should take it in for service.

It could be a faulty knock sensor, or a faulty cam position sensor, or a multitude of things, but the service department should be able to figure it out for you. It may even have set a code. Does your MIL (Malfunction Indicator Light) come on when this happens?

i have a 6MT and yes i did try different octanes (91 and 93) from different gs stations but it still limits the rev at 5500 rpm. There is no MIL, the car seems to be completely normal other than the rev limit. i will have to take it to the service dept after all. thanks for the input guys ...really appreciate it a lot.

My guess

To borrow from my S2000 experience, you may have an issue with a manifold air pressure (map) sensor.

If this thing is not happy, you can not go in to vtec mode and the engine sputters in a most unhappy manner.

They may just have bumped it during service so the contact is off.

The dealer should be able to diagnose this pretty easily.

direk_04TL

i totally agree. however, wouldnt this behaviour trip the SERVICE ENGINE light?

clutchcargo

Hi Direk,

I agree with your logic but in the S2000 , no warning light is triggered.

The car runs perfect up to the vtec changeover point then sputters miserably.

slajan

and cluthcargo, thats exactly whats happening with the TL...serious sputters and car refusing to go at higher rpms

Hey, I am currently going through the same issue with my 03 tl. My issue started when I had the 1st transmission changed out. Mine is an auto, it hits 5500 rpm and bounces like hitting a rev limiter, but mine is an auto, so it has an added issue. It will not allow the car to change gears. If you have any ideas or any comments. Please let me know as well. Ill keep you updated with the outcome of mine, but the bad thing is this is the 10th visit to the shop and they have no idea. At least its under warrante!

Holy thread resurrection! I have an 01 CLs 5AT and, and have experienced the same issue.I believe it has something to do with the PCM/ECU. More specifically, in relation to the tranny, MAP sensor, or CPS. I say this because I get the problem in one specific situation. It happens when I am on the highway, in 4th gear for a bit, and drop down into 3rd gear at around 70 (VTEC engagement). It will often rev limit at 5500 yet if I upshift to 5th gear, drop back down to 4th, then drop to 3rd, it does not happen. This is what leads me to believe it may have something to do with how the ECU/PCM. Any engine codes thrown? If so I would definitely make an appt for the tranny. If not, get the ECU/PCM checked out.

nightrider, were you able to get this issue fixed? if so was it a definate fix and how did you know what the item causing the issue was. Did your car go into VTEC?

TLgirl34

It's kinda random, but a friend of mine with a 4-cyl accord described similar symptoms except the check engine light came on. He took it to auto zone to have the codes read and it was something about the air fuel mixture (I don't remember the exact verbage). Anyways, long story short, while they were messing around with it, they figured out it was 2 quarts low on oil. They topped him off and reset the check engine light and everything has been fine since. Apparently the VTEC is oil activated and if you don't have enough oil, no VTEC for you.

got my car back from the shop. Truned out that it was a connector that had a bent pin. They replaced and fixed the problem. Dont know it that will help you out. but maybe?

For what it's worth...I found out that the revs are limited to 5500rpms with the e-brake engaged, but should be free revving otherwise...

NightRider

Mine had something to do with the either my VTEC controller or the oil. Once I got the oil changed, which is around the same time I took the VTEC controller off, no problems ever since. If it was the VTEC controller it was because it was throwing off the a/f and cam timing.
