What should my throttle position read?
What should my throttle position read?
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.
When does the throttle position sensor read 19%?
All of the sensor readings seem to be accurate, with the exception of the throttle position sensor, which reads 19% when the car is at idle with my foot off the gas. When I accelerate, the throttle position climbs correspondingly.
What should the ohmmeter read when the throttle is opened?
When the throttle valve switch is turned on, the ohmmeter should read resistance around 0 Ω. Slowly open the throttle valve and when the switch opens the resistance should be equal to infinity and remain the same even if the throttle is fully opened. Connect ohmmeter between the ground and the full load mode terminals.
Which is the correct position for the throttle?
The ECU will use voltage as a reference to a bad TPS, not position. 5v usually for a bunk sensor (eg, a short). You calibrate voltage to its relative position. There is some play, generally, to adjust it physically. While the voltage is within a range, the position of the throttle can certainly be 0-100. 0= your foot’s off the gas.
What happens when the throttle switch is closed?
When the throttle switch is closed, ohmmeter must read circuit break (infinite resistance). Slowly open the throttle valve. When the switch opens it should click and the resistance should remain equal to infinity. When the throttle valve opening angle becomes greater than 72 degrees, the resistance will be equal to 0 Ω.
What does it mean when you say throttle open or closed?
Answer Wiki. Petrol engines have a throttle plate that restricts air to the engine. This is a butterfly or slide valve. With the ‘throttle open’ full air pressure gets into the engine and it produces maximum power with the ‘throttle closed’ the engine moves to idle. Partial throttle gives you the power between full power and idle.
What should voltage be at wide open throttle?
The initial voltage reading should increase smoothly as you open the throttle plate to its wide open position. At wide open throttle, you should see about: 4.5 to 4.9 Volts. Now, slowly release the throttle plate to its fully closed position, all the while observing the multimeter’s reading.
