i have put a new fuel pump on. no change. and i don't have any warning lights on. how do i check the throttle position sensor?
I have a extensive thread on this. You need a extremely accurate digital meter , preferably with a 2 decimal place reading ability and the Kawasaki harness . The part in 52Degrees mentioned about dipping is accurate and something I would look for when having inverter misfire/ hard tripping, some older inverters couldn't run without a signal, a spot where the wiper made contact on the wire wound resistor could get fouled with dirt / air contamination. There is a extensive test in the service manual, not all of those tests are with the key on. FYI that harness is about $20 and the tests are main and sub throttle position sensors .
I also mentioned the crankshaft position sensor as to corrosion. I still would put my money on either the main or sub sensor , one of those tests is the supply voltage, this is a 5 VDC operating system much like a USB power, 2015 on, all the sensors are powered by 5 VDC .
That is why I suggested checking that area.Also when I say accurate meter, use alligators, when measuring ohms , pay attention it says with power off, not that it matters but if you have a REL
on your meter, I think the range is 10k ohms for the test, you press REL and short your leads out, the meter subtracts the value of resistance of the leads, however to be honest, the most your leads should be is 2 ohms, so I doubt you would see a difference.
Use alligators and you may need to read the instructions in the manual several times to grasp the method, I have explained that in my post and actually added coloured tape to my harness as their explanation in the manual suffers from translation problems into English.
I have updated that thread and also found my settings for reference.
