Can I reset a Vance and Hines Fuelpak?

You don’t need to “reset” it. If you’ve got the new settings for the new pipes just alter the current settings to the new ones.

Does TPS control idle?

TPS gives to the onboard controller information about the idling, deceleration, rate of acceleration and the fully open throttle valve state (WOT). Based on the received voltage, the onboard computer can calculate the idling (below 0.7V), the full load (about 4.5V), and the opening speed of the throttle valve.

Why is my Harley in limp mode?

Limp Mode happens when there is a correlation error between the twist grip sensor, electronic control module, and throttle control actuator. It limits the RPMS and throttle response of the bike. Basically, it lets you limp the bike home or to a shop to get it repaired.

Why does my Harley idle so high?

A motorcycle idles high when it is getting too much of an air and fuel mixture in a low speed or neutral position. This is usually caused by the idle screw on the carburetor being out of adjustment, an out of place throttle handle screw, a bad carburetor throttle spring, or a sticky throttle or throttle cable.

Will the Fuelpak void my warranty? Answer: Some dealers will still honor the factory warranty after a Fuelpak installation, but some will not. It is up to your dealer. Often the dealer will honor the warranty if you pay them to do the Fuelpak installation.

Is the Vance and Hines FP3 worth it?

The FP3 reminds me of those days of simple and cheap performance upgrades. For the price, ease of use and performance results, I highly recommend the Vance & Hines FP3. FOLLOW UP 3 months later: Since I installed it on the stock header and pipes, some things have changed.

What should TPS be at idle?

At idle is should be zero or a couple of degrees. Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. If the TPS has a worn spot, most likely it will be between 0 and 20 percent throttle opening. Try holding the throttle between 0 and 20 percent to see if you get a steady reading.

What are symptoms of a bad throttle position sensor?

Can I unplug my TPS sensor?

If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration. Correcting the TPS then produced a correct idle, and no code.

What happens if TPS is not calibrated?

If the TPS fails to send the proper data back to the computer, the correct fuel calculations can’t be made. With some engines, other sensors are able to compensate and provide a guess at how much fuel is needed, but this usually causes the engine to accelerate poorly or sporadically.

How do I test my TPS?

Test the TPS using a digital multimeter. Make sure that it’s still working and, if necessary, visually inspect and test the wires and connector. If the sensor tests OK, erase the code. If it comes back or you notice a performance issue.

Can you drive without TPS?

The TPS or Throttle Postition Sensor tells the ECU how far the throttle is open, thus how much fuel is demanded. You will still be able to drive without a TPS, though not very well. The ECU will see a lean condition from the o2 once to open the throttle and it will atempt to richen it up.
