Bike into the shop today;
told my throttle position sensor may be blown. if this is the case, the sensor comes attached to the metal piece it is screwed to and costs over $1000.00.
Anyone had to replace this unit ?
the FI blinked once, twice and eight times, it was the eighth time that indicated the throttle position sensor - mechanic is checking the wiring from the sensor to the computer and suggested it could be the cable or the fkking computer -
Anyone had to replace the computer in their hornet ? Not many wrecked hornets here, sydney australia, so not many second hand parts for the hornet.
I have everything crossed it is only the cable wiring, but if not, I will have to wreck my wallet for wreck my hornet - it is a 2002 model with 54 thousand kilometers on the clock, so is old, but not very worn.
Hmmmmm, I'm hearing my BCHS auto shop teacher again, a brilliant guy Willie was. This goes back over 40 years and if anything, it rings more valid now than it did then. He was ahead of his time. One of the best teachers I ever had.
"Guys, what was the last thing you did to the car, or the last thing the last guy did?"
"Guys, don't be a parts replacer!"
"Guys, always start by going back to the basics first. Higher level diagnostics go by the ladder of complexity".
"Guys, diagnose first, then fix."
"Guys, diagnose correctly first time so you only have to fix it once."
I've not heard of a duff ECU so view that as unlikely.
Have you tried to self check feature off your dash?
I trust you have the factory manual for all the codes info.
Keep in mind the following based on your stated 1, 2 & 8 blink code faults.
1 is MAP related ONLY
2 is MAP related ONLY
8 is TP related ONLY.
All three fault codes are for connections faults and/or duff sensors.
None indicate ECU involvement.
Unless an electrical event has fried multiple sensors at the same time, that leaves us with the probability of there being zero chance of a MAP and TP independently failing at the same time.
That leaves us with the only common denominator across all 3 codes that does not involve sensor failure(s), namely connections, in other words, continuity.
Hopefully the above helps you.
Try a PM to Mr. Tharlson if he does not chime in on this thread.
