(Car: 98 GSR)
Alright guys, ive been troubleshooting this for days now. Its getting old.
Okay, so the VAFC install went smoothly, didnt install the VTM wire initially...alright.
So, like a million other guys, i was on the highway, did a 5th gear pull, CEL, code 22. Ah, oil pressure sensor! Ah, Apexi has updated instructions...oh look, i need to install the VTM wire. Done.

However, we still have the problem --- you know the one, revvin it to 5k and it is in a safe mode of sorts...wont let you go...rev limits...
But, this only happens on the highway, in 4th or 5th gear pulls...never when im jettin around town redlining 1st or 2nd...only the high gears.

Ive resoldered the VTM wire already, the connection is perfect.
I have no clue what else to do...I realize some say clean the vtec solenoid, but having this happen right after the VAFC install just seems too fishy for it not to be the VTM wire. Can anyone help me, anyone...please. I cant stand garbage like this.

Oh yea, another piece of info to make the story a bit better....just installed my skunk2 cams, gears, valvesprings, and retainers, within a week of the VAFC install. However, this install went flawlessly, with no issues whatsoever...so just take that into consideration.

Well, thanks for reading thus far guys...please, if anyone would give me something, anything to work with, it would be appriciated.

did you reset your ECU after reconnecting?

 

yessir, nearly 4 times by now (you know...figured maybe the first 3 times the car just wasnt getting the point )

hey you know what? quick side note...my friend redstargsr said i can pull the hazard fuse to reset the ecu...is this true?
thanks dlo,
rob

one more thing --- when you pull the harness out of the ecu, and replug it in, does that reset it also?

 

bump for the night

 

Rob, it's probably a bit of a long shot on this one, but try swapping MAP sensors with somebody.

The only basis I have for this tho is way back in '98 my brother's GS-R had the same problem with his Field's VTEC controller. After the MAP sensor was replaced, he said it was just fine.

 

just unplug and replug the battery

 

Robbie, take out the motor, suspension, and interior, buy a crappy hatch and you'll love it. Trust me. I have been reading a couple of threads and have asked a few people to check out this thread so we'll see what they say. As for now, check to see if you have a dented oil pan or something of the sort. I don't see how it could be a wiring related problem. Also, I read that you should try and connect a wire to your Vtec Solenoid and to the pos. side of the battery and if you hear a clicking than it's good, if not, it's bad. Just what I've read. Good luck man

you pull the radio memory fuse for about 30 sec. and that resets the ecu.

 

oh i realize that resets the ecu, but it resets everything else too (i.e. vafc, radio, etc), trying to find away around that.

 

ben, how exactly do you switch a map sensor...?
also, do you think we couldve messed with the vtec solenoid on the install??

 

Solenoid wasn't even breathed on when we put everything else in.

MAP sensor is the small black box with two feet (where the screws are) on top of the throttle body.
Swap MAP sensors by removing the two small phillips screws and teh vacuum line & wiring harness socket. Install replacement reverse of removal.

Is it still giving you code 22 when you experience this problem?

 

Yes, as of last night I know it happened. Is there anyways to check the Map Sensor to see if it's bad before we replace it?

hey buddie...check this...when i did my vafc install i ran a tps wire code...cant remember what one but u get the point. i found out that after i started the car and actually flipped the ecu over and just tried to reposition the ecu the code went away. check to make sure it isnt a short in the harness by starting the car and moving or flipping the ecu over. i know its a long shot but it fixed mine. also if you havent done so already put the old gsr ecu in and try running that to see if it will shoot out that same code. good luck bro and call me up IM me or whatever so we can get this fixed. oh yea also look under the hood. there is a fuse that is specifically for the ecu, pull that one instead of all the other fuses. it seems pointless to pull a radio fuse to reset ur ecu. u know the rest of the routine.

Since you're still popping 22. I'd be willing to bet that it's not the MAP sensor. Let me link you to some CEL 22 posts. There have been plenty of them.

That's all that I could find for now.

 

yo marsh, this has all been happening on the stock GSR ecu...sent the jun one back in place of a kenji.

ben, thanks for the links...unfortunately i beleive ive seen all of them.
ot: ben, thanks for the help again.

 

^^

 

anybody else have any ideas? please.

 

i guess noone else has any experience with this issue...

 

my .02
remove the VAFC and make sure vtec is still working
if it is, re-install and recheck everything.

im thinking the VAFC is bad. but i could be wrong.
also make sure the wiring for the VAFC is in good condition, my buddy had a spliced wire in his prelude and caused a 22 and limp mode.

I would say go over your connections again and make sure you didn't bend any pins at the back of the computer.

 

I had the SAME problem. Mine was just loose connections. Make sure all your wires a connected! After this experiance I SOLDER all my wires together.

 

hey man, i read a couple of your posts about it. see, unfortunately all of my wires are soldered...and imo they are soldered quite well...i can literally pull on them and they wont budge...do you recall which wire it was that had a loose connection?
thanks so much ---
oh yea, yours does work now, right??

 

you there BVM??

 

Check your oil level. My car does it sometimes too. Whenever it does it to me, I just shut the car off, turn it back on, pop the clutch and I'm out of Safe Mode. Dont ask why, I dont know.
