What should throttle position 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. You should see the percentage of throttle opening gradually increase to 100 percent at wide open throttle.

What percent should TPS be at?

The TPS on a ETC (Drive by Wire) car should be ballpark 8-18% (it will depend on your setup, but these values would be a reasonable median value), so what your seeing sounds normal.

Is throttle body open at idle?

In that case, the throttle body blade will be able to close entirely when your car enters idle. Even when your throttle body's blade closes entirely, some air has to get through to the intake manifold. Otherwise, your engine would stall.

What are the symptoms of a failing throttle position sensor?

What is relative throttle position?

Relative Throttle is the throttle position compared to the learned closed position. As in, if 9% Absolute is with the throttle fully closed, then Relative will read 0% in the same position.

How to Stop Car Hesitation (Throttle Position Sensor)

What happens if TPS is not calibrated?

If your TPS is faulty or uncalibrated, the sensor will be unable to accurately determine the position of the sensor. This will lead to a variety of symptoms, all of which are caused by the fact that the ECM is delivering the wrong air/fuel ratio to the cylinders thanks to the bad sensor.

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.

How do you reset a throttle body?

Leave the key off for a moment, turn the key to the "On" position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.

How do I reset my accelerator pedal sensor?

Resetting your electronic throttle control manually can be a tricky job. First, make sure the accelerator pedal is fully released. Next, turn the ignition on and then turn it off and wait for ten seconds. During these ten seconds, be sure the throttle valve is moving by listening for a sound of operation.

Should throttle body be closed at idle?

A small airflow rate at engine idle is required to maintain a low engine speed and to save fuel consumption. Since the throttle plate is almost closed at idle, the plate and bore tolerance becomes important in determining the plate open area and thus the airflow rate.

Is throttle body supposed to be slightly open?

Most if not all butterflies on throttle bodies do not close all the way. It stays open to a predetermined gap. The IAC further regulates how much air to increase or decrease as needed to maintain preferred idle.

Is throttle plate closed at idle?

At idle, the throttle plate in a port injected engine is completely closed!. The air needed to keep the engine running is supplied by an idle air bypass valve and a passage the runs from in front of the throttle plate to behind the throttle plate. is cracked slightly open to all enough air to maintain idle speed.

Can TPS cause misfire?

If you start to experience engine misfires, stalling, or rough idling when the car is stopped, it can also be a warning sign of a failing TPS.

How does electronic throttle control achieve the correct idle airflow?

Normally, at engine idle condition, the electronic engine control is intended to operate the engine at a fixed RPM regardless of load. It does this by regulating mass airflow with the throttle command from the driver at zero.

How do you diagnose throttle body problems?

How do you fix high idle after cleaning throttle body?

Cleaning the throttle body allowed more air to enter the engine, and the computer is compensating by adding more fuel. The idle will relearn if you put the vehicle in drive and allow the idle to come down with all accessories off for about two to three minutes.

What causes throttle body failure?

Possible causes of a malfunction

One of the main causes of a malfunctioning throttle body is internal contamination. Due to the contamination accumulated in the throttle body, the throttle valve can no longer move properly, causing problems with the control of the air supply.

Can TPS cause high idle?

It could either stay shut or it won't close properly which is a severe issue. If it stays shut then your engine is not going receive air and it won't start. When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle.

What is idle relearn?

In the event you are experiencing an erratic idle after loading a tune or after performing any action that clears KAM (Keep Alive Memory), an Idle Relearn can help you get back on track. The KAM or “Keep Alive Memory” is the memory that is stored in the powertrain control module (PCM).

Does a new throttle position sensor need to be calibrated?

Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to "TPS Raw" in the Analog Settings.

What does closed throttle mean?

When you're approaching a hazard or a difficult to read road situation, you should come in on a closed throttle. This automatically reduces your closing speed (see the article from last issue), sets the bike up for a quick direction change or a stop.
