Ltr450 testing the Throttle position sensor 

Heck yea man! Suzuki for life! Hahaha

I believe in my next video I explain on how to use a meter to set it if it wasn’t in this video.

Clockwise/ counterclockwise is the direction in which the sensor spins when the throttle is twisted

Tps sensor or fuel filter are the first things I'd check since it's a common issue on these quads

First thing I would do is clean all your fuel filters and make sure you got a fresh plug and air filter in her. Then go from there.

It’s a ltr450?

I believe I cover that in the next video. If I'm guessing I'm pretty sure it was the wires on the outside. Not the one in the middle.

You check your fuel filters yet?

What year is your ltz400?

09

So I went back and checked my video. And it shows mine spiking up 3.6#. I would assume there is definitely more then one way for a tps sensor to fail.

Is it leaning popping at all? Just make sure you check all those fuel filters too.

Thanks for replying yeah I went ahead and changed out the fuel pump,did a rebuild kit on the fpr...deleted swirl and a new Injector...bogs down after it's been ran a little hard will cruise fine.. it also has a fuel pak installed not sure if that could be the problem but I'm kinda leaning on the tps because of that reading I got...thanks in advance

R Carr what is a fuel pack?

Not to familiar with it just bought the quad but from what I understand itll adjust the air/fuel mixture for the exaust and air filter setup it has...like I said could be wrong but that's what I was told

Yep. After we put that in it ran great. Just make sure you test it and you know it’s bad. I bought a oem tps for $160

Full Speed Impulse which wires did you use to test it kinda having same problem bogs at low rpm

The outside ones. Not the middle

The red and yellow wire. Should be the three wires total. It’s the ones on the outsides. My next video labeled Ltr450 runs+massive burnout shows exactly how I tested it. Thanks for watching!

@@FullSpeedImpulse thanks man im currently working on mine trying to set my tps up

Alright bud. Hit me up if you have some more questions. Thanks for the view and comments. Hit that subscribe. Will have more quad and dirtbike action coming soon!!! Thanks!!!

@@FullSpeedImpulse will do. What should it be set at. I just wanna triple check

.60 should be what it rests at. If it is incorrect your FI light will go on showing it incorrect.
