What should throttle position sensor 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.

How do you reset a throttle position sensor?

The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.

Is the TPS on Keihin FCR necessary or not?

I found out by simply disconnecting it. It was the last step on my research as I had problems in acceleration, that felt like ignition failiures.

How to set the throttle position sensor ( TPS )?

Choose the mV setting if your meter has the option. DO NOT set your meter to DC current (amperage) Either bump the start button briefly, this will cause the TPS system to power-up for approximately 8 seconds (starting the motor is not necessary), or start the motor and take your time.

How to tune the carburetion on a Keihin FCR?

Keep in mind that you will spend much less time tuning the carburetion in following order: 1. Main fuel jet and main air jet (must be selected first since they feed the emulsion tube, which feeds the needle jet and jet needle). 2. Needle: a. root diameter b. taper c. clip position (which includes the L1 measurement) 3. Slow fuel and air jets. 4.

How do you adjust the throttle position on a car?

1. Loosen the jam nut and unscrew the throttle stop screw all the way so that the throttle blade closes fully against the throttle body itself. 2. Turn the stop screw back in until it just touches the linkage, then turn in ¼ turn more. This extra ¼ turn keeps the throttle blade from sticking against the inner bore of the throttle body. 3.
