What does it mean when throttle position sensor is high?
What does it mean when throttle position sensor is high?
If you notice that the reading is close to the battery voltage, then the ground is good. However, if not, there might be a problem with the power supply. On visual inspection, if you don’t find anything wrong with the throttle position sensor, it is time to test the voltage at the sensor.
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.

Can you test the throttle position sensor on a Lincoln?
Testing and troubleshooting the throttle position sensor (TPS) on your Ford or Lincoln car, pick up or SUV is an easy thing to do. You don’t even need a scan tool to test it.
If you notice that the reading is close to the battery voltage, then the ground is good. However, if not, there might be a problem with the power supply. On visual inspection, if you don’t find anything wrong with the throttle position sensor, it is time to test the voltage at the sensor.
What does inline mean in throttle position sensor Elec?
You need to connect one end to the 5 volt reference sent to the TPS from the ECM and the other lead to the center wire coming out out of the TPS. This is what they mean by inline. While doing this, with the key on, move the throttle plate and the voltage should change smoothly. It is the smooth change in voltage or resistance we are looking for.
How is the idle position of the throttle valve determined?
Idle position of the throttle valve is determined by the ECM receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.
Where does the voltage from the TPS sensor go?
An excessively high voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM).
