Ok so here goes. This post is going to contain a ton of info and is a problem that I have never seen discussed anywhere on the internet because I have searched the hell out of it. I kinda don't even expect it to get replies since it seems no body has ever run into this issue before but I'm asking anyway.
2003 ZX-6R 28k miles.
Problem: FI light, code 32, Sub-Throttle sensor malfunction.
Info pertaining to the problem: I've had this problem since I got the bike over a year and 12k miles ago and I'm getting sick of knowing that there is a problem with my bike.
A few months ago, after a valve adjustment, the mechanic switched the main throttle and sub throttle sensor plugs which caused all hell to break loose on the ride-ability of my bike. While chasing that problem down myself the service code switched from code 32 (the problem I'm having now) to code 11, main throttle sensor malfunction. After referencing the manual I noticed that the input voltage range of both of those sensors are identical and the output voltages of those sensors are damn near identical. This leads me to believe that the actual sensor is fine since the code 32 disappeared while the plugs were switched.
This lead me to think that there was a short in the wiring somewhere that carried an input or output signal from the sub-throttle sensor. Earlier this week I ordered some posi-taps (the things that are used to power stuff like power commanders) to jump the wires direct from the sensor direct to the ECU. I was so hopeful this would solve my problem but nope, exactly the same.
I've been staring at the wiring diagram for my bike for hours trying to find out how there would still be a problem and I cannot figure it out since I'm more mechanically inclined than electrically inclined.
There are three possible solutions that I can imagine.
1) The actual sensor is bad and the fact that the code switched after my valve adjustment was just a fluke. I would need to order a new throttle body assembly.
2) The ECU is bad. Skeptical of this too since the bike has run as good as I can tell since I've had it. I would need to order a new ECU to fix this.
3) My thought that it is a wiring problem is correct but I just can't figure out how the wiring harness is broken. A solution to this might be to replace this section of the wiring harness...
And if that didn't work I would have to order an entire wire harness.
Ok so if you made it to the end go have a beer and call your old English teacher and tell her you just read a damn novel. If you have any clue as to how to solve this issue, you wont ever realize how much I would appreciate that. This problem has me beat...
