Got my car back.Redline problem. Car not going past 5500-5600 rpm
So I got my car back last week, and ive been testing everything out. My car is redlining at 5500. do you guys have any idea what could be the problem? my car did roll over, and now all i can think of is could it be possible that something is clogged? should i change my spark plugs out? help guys! its kiling me

If I'm not mistaken it's has something to do with the transmission. The car doesn't know it's out of park. So it's limiting the revs. I'm not sure how you resolve this.
It's not oil related.

sad thing is that it's not throwing any codes. Also i dont think it has anything to do with thr transmission. i used the harness from the cl, no splicing was necessarily. can you guys show me where the vtec module would be?

I think rob is on to something with the car thinking its in Park gear and the rev limiter is 5000-5500 in park
Only in drive gears will it go to redline
With a rollover crash there are various sensors that would try to protect the engine
Normally in a roll- the car sits upside down for some period of time, far longer than it was ever intended to, which would be... Not At ALL
Oil gets into places it never should when it sits upside down, you dont like sitting on your head, why would your car?
The vtec operates on sensing oil pressure change and whatever at 4500-4700 rpm and uses oil pressure to operate the vtec system
If a module was damaged or there is a computer thing??
Say, have you tried resetting the ECU??- pull the `clock` fuse on passenger side of cabin
think its #13 - check the diagram on cover panel
pull the fuse for a minute and reinsert
See if the car runs better
Only do that after every effort to get codes- it will clear all codes
Acura has a different code reader than we can use at the parts store. It reads things they wont
Ask a body shop what happens when you roll a TL- what do they have to do?

Gotta ask JUST IN CASE.
Are in park trying to rev to Redline? In wont if its not in Drive.
Just to get that out of the way.
EDIT: IT Said 03 CL-S 6MT under ur name? Are u saying u have an MT or an AUTO?

Its strange there are no codes and its limiting you. It should flash a code if you are in some sort of limp mode.
I think rob has the right idea, just not that its in park.
Look at the trans there has to be a speed sensor damaged. If its not letting you rev the motor must think the car isnt moving

yeah, its kinda odd how there's no codes. Anyways, I resetted the ECU, just havent taken it out for a ride yet. What would i have to check for to find out which sensors are screwed? also, where is the location of the vtec solenoid?
#13
Senior Moderator
Its not the VTEC solenoid. Even if that wasnt working you would be able to go to redline. Look at the trans and all connections on it. Look for any that look damaged, bent or different. ook at the wires.

ill definitely check that out tomorrow. i resetted my ecu yesterday, and now i notice a new code that showed up. havent been able to pull it yet, but i'll let you know the code(s) when i do. also, i noticed that after the check engine light turned on, my car is really jerky when im in gear and i release the gas pedal. like it'll jerk back and forward. also, the idle is really erratic. it would go down to 750 then jump back up to 1500, and you can hear it do that constantly. any idea what that might be?
#15
I think being upside down moved some crud around and the IAC valve on the TB assembly is dirty and sticking or something along those lines
I would ask a few body shops if there is a known issue- and look under the car for a wire unplugged or damaged
With your custom install there may have been some confusion
Like when we put an rx7 rotary engine in a 626 mazda formerly 4 cylinder rwd model
The body shop guys (owner stuffed it into the first available pole)
wondered why there where 2 cross members-
was this engine an option on all of them??? they asked

The thing is that he was the one who did my car before. I didnt have this redlining problem until after the rollover which means it's worked before. i checked the transmission and engine for loose cables, but unfortunately couldnt find anything. the next step for me is cleaning out my IAC valve, which i plan to do right now. although this problem did exist before the rollover, do you think cleaning it might get rid of the porblem?

that code was for the IAC valve. no sensors. I actually just took everything apart and inspected the transmission for bends breaks and missed connections, but unfortunately, i saw none. I just talked to my neighbor a second ago, and he said there could possibly be a transmission governor inside the housing that's not resetting. is that possible?

Oh and also, the IAC Valve has already been fixed. I took it apart today and i found out that the lil biatch was gunked up with something that didnt allow the valve to spin. i sprayed so much carb cleaner in it and after spinning it around a few hundred times, the valve spins smoothly again. now back to the original problem. you said it could be the gear position sensor, can someone show me where the location of that sensor is? i'll take a look at it tomorrow

Im still thinking it has to be one of the speed sensors. (i don't have the manual near me to look where they are) If it were any other sensor or problem i would think it would throw a code. Though i don't know why its not now?

6MTUA5, My speedo does work. Everything is perfectly normal.
Phee, Why would i use the TL harness when i bought the whole front end of a 6-speed CL? The thing you have to remember is that it all worked before my accident, it was after the accident that this problem started.
Kris, I have a feeling it might be the speed sensors as well, but the thing is, I've already searched the engine bay and the tranny housing to check for cracks, dents, missing adapters snipped wiring, but nothing was found. there was no damage to the engine bay as far as i can see. there's not many scratches that i see either which is what i dont get. I checked the inside of my car to see if there's any loose connections, but I dont see any either. The whole no codes thing is pretty annoying as well.

Turbo do you have the MIL on? Get those codes read if you do. I would check your speed sensors. There's two on the trans. Also check the tps sensor for smooth voltage increase; at idle it should be .5 volts, at wot it should be 4.5 volts.

Search how to post pics up. It can't be too hard to find how to do it. Maybe you bumped a connector loose when you changed the starter out? Check the wires around the vicinity of the starter.
#34
I've been over ever single plug and wire 10 times to no avail. I'll try and post the pix when Igget off work on the computer. Only other thing I did was change my radio. Been over it 5 times and even put it back how it was. Still have the issue. Car runs perfect otherwise.

Ok so update, on the interstate on the way to work I decide to punch it.. It rev all the way to 7k like it'sssupposed to numerous times. Got off the interstate and stopped at a light. Punched it and guess what? Vsa light flashed with liss of traction and the car only reved to 5500 again? So maybe it's only lower gears? Please help!

Just to make sure turbo, have you checked the things the people told the op to check? The trans range switch and the vtec solenoid, also your oil level? Those are the most common things causing a red line issue. It never hurts to go over the simple things again.
