Should throttle body be closed when car is off?
Often deposits become thick enough to prevent the blade from closing all the way – even when you take your foot completely off the gas or put your car in idle. In that case, the throttle body blade will be able to close entirely when your car enters idle.
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.
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.
How can I Reset my throttle position sensor?
Reprogramming or resetting your sensor can sometimes solve these issues. This step can also be necessary when you install a new 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.
What do you mean by Absolute throttle position?
Absolute Throttle Position — The absolute throttle position (not the relative or learned) throttle position. Usually above 0% at idle and less than 100% at full throttle. Calculated Load Value — Indicates a percentage of peak available torque.
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.
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.
