High idle after riding

[Msmitch459]

You may want to clean your throttle body linkages as well.

Cleaned. No change

Using the app on my phone I saw TPS at 0 at normal idle and it would change going up as I moved the throttle up. When it was stuck in high idle the TPS read 1 and would not go lower even though the throttle was all the way back at home position. Bad or good?

Steve I am not up on the phone app so I can not speak to whether the numbers you posted are volts or percentage. Have done a full ISCV RESET and if so what are your voltages on the tps? It should be .60 +/-.02 with the stepper motor fully retracted and .72 +/- .05 after you tell the motor to move in .12 volts. What readings are you getting? Personally I think you tps is worn but would like to know the readings first before I take a chance and put my boot in my mouth. Of course any of you smart phone app people feel free to speak as to whether the phone app looks like the normal computer app. Oh and screen shots for traing aids are a good thing.

For Android, this is what it looks like on a "Tab" - Don't know bout phone, I think the same tho....

Ok great now I have a better idea. Can you post what the ISCV reset screen or tell me if it show voltages. This is what steve needs to look at as the voltage points and changes are more finite or smaller increments. Its hard for me to explains but the ecu is a computer and has different types of variables some for math and some for compensation think of it as zero percent throttle is different depending on the air temperature so it can idle right whether its 32 degrees outside or 80 degrees .this way it can look at the required air fuel ratio the out side temp the engine temp throttle position engine load and squirt the right amount of fuel. I do not want to confuse people but the ecu is running a lot more caculations and reading in the background then some people realize aftet all it is a computer. My bet is a bad tps but i would fist run ISCV reset which it homing the machine to a constant base line and if it acts up it is most likely getting a false or inconsistant reading from the rehostat / TPS. I hope this makes sense and I am not confusing people. If so I might be anle to explain it on the phone verses typing.

Thanks for the pictures.

Yea, I'm not at it now but when you hit the set ISCV box, it takes you first, to setting the TPS volts, then goes to the box to set ISCV volts. Hope that helps

Thanks I was hoping it had it. I still am willing to bet steve has a bad TPS SENSOR.

hi Steve, I have the same issue with my 08 classic. it was down right dangerous!. I cleaned every linkage and every spring; I reset all my perimeters in my map but the problem persisted.
I then decided to remove my idler stepper motor as shown in Warp 9.9 photos. I took the rubber boot off and soaked the motor in WD 40. I then pushed the "arm" in and out about a 100 times (exaggerated); replaced the rubber boot and put it back on my bike. I then reset my map tune and gave her a 12min tune. hey presto, bob's your uncle, all fixed! that was a year ago and no more problems. I think it was just gummed up with dirt and needed lubrication.
maybe this will work for you. total cost was about 1hr of time.
cheers

Thanks. I took it in to be sure and they told me to change the TPS. I'm just waiting for it to arrive. Maybe I'll try this while I wait.

Is the Primary TPS up front or back by the seat? Page 171 shows it in back by the seat.
Triumph Rocket III Service Manual (Page 171 of 425)

I ordered part number 2 from Bikebandit and it is the front sensor.


Who has changed this and which one is it? I'm thinking BikeBandit has it wrong but I needed to know before I call and complain.

I have a 2009 Rocket III
