Servo tick, tick, tick

Hey everyone, new to this so please bear with me. I am hoping to get some direction regarding my 2003 cbr 954. I reset the diagnostic system and after doing so I am getting a constant tick sound from what I believe is the servo motor. If anyone has any insight as to what this might be or how to solve the prob it would be greatly appreciated!!!

Thanks

Re: Servo tick, tick, tick

to the site! You must be talking about the servo that controls the intake flap and the exhaust valve. The internals are I believe a set of 5 gears, if it's ticking, check if one is stripped. Do you get any FI code?

Re: Servo tick, tick, tick

Hey, thanks!
The reason I reset the diagnostic was because I was getting a solid (red) on the indicator after riding for 10 min. The ticking was not there before I reset the system. Now when I turn the key on (no sound) until I turn on the run switch, then the ticking begins and does not stop. I still get the solid red but no other series of flashes to reference.

Re: Servo tick, tick, tick

The servo does not receive a signal before 3k rpm, at which it rotates the first 90 degrees.

Does it sound like a relay?

The servo is on the left side under the tank/seat. take a listen and see if thats the problem

Did you keep riding? Did you notice a change in exhaust note and power overall?

Re: Servo tick, tick, tick

I did keep riding for another 10 min to get back home and didn't notice a change in power although I was a little gun shy and kept the rpm below 4k. I just checked the diagnostics again and I'm now getting 3 long - 5 short which is described as a faulty egcv and air intake valve servo motor. The sound is a tick combined with a softer buzz and is coming from under the tank.

Re: Servo tick, tick, tick

What I don't understand is why this occured after reseting or shorting the diagnostics. This noise occurs immidiately and while the bike is idling at less than 1.5k.

Re: Servo tick, tick, tick

just to clarify, you reset the diagnostics, went for a ride and then it happend, right?

Sounds like you have a manual. You can test the servo, but first it'd remove the cables from the HTEV and see if the valve turns freely, carbon tends to build up and block rotation, causing the servo to get stripped. If its free, follow the procedure for code 35

Re: Servo tick, tick, tick

Sorry for the confusion. No the solid light came on during my ride, then I rode her home and reset. During the reset process the noise began. I shorted the system under the seat, turned on the key, (still no sound). It began when I removed the short wire and then put it back as described in the manual.

So now you have code 35 and the noise with the ignition on and the killswitch in the 'run' position?

Sounds like the HTEV is jammed and the servo is grinding itself since it is trying to set the valve to the 90 degree position.

Have you removed the cables and rotated the valve by hand?

Re: Servo tick, tick, tick

Absolutely magic...I hope. The noise was defiantly coming from the servo once I took a closer look I could see and feel it trying to turn. I removed the cables from the exhaust valve and when I spun it, it did sound and feel like there was some carbon build up. I then fired her up and the noise was gone as was the pgm-fi light. My only remaining question is that if the servo doesn’t turn until 3k why was it trying to turn at lower rpm. Is it a second turn at 3k? Could it now be stripped and still seem fine until I get her back on the road? Anyways I guess I will find out when I put her back together and hit the street tomorrow.

Thank you so much for your help!!!!! The next time I ask a question I’ll be sure to be better prepared to troubleshoot before I ask!

Thanks again

Re: Servo tick, tick, tick

Ps. If you come up this way let me know. The sea to sky up to whistler is an outstanding ride! Winter games athletes are not the only ones benefiting from the infrastructure developments up here! There is also some great riding on van. Island.

Been a long time since I had mine connected but I don't think this is correct.
I first heard my servo while sitting at a traffic light.

Re: Servo tick, tick, tick

May be a silly question but what mods do you make to replace or bypass it. You still need something controlling your exhaust valve do you not? Because it is 200.00 for a new servo and if it goes I'd rather modify as opposed to replace.

No.
Just set it to one of the positions and disconnect the cables.
