Where is the throttle position switch on a car?
The throttle position switch signals the movement and position of the throttle valve to the Engine Control Module (ECM). The switch unit is installed at the throttle housing and attached to the throttle butterfly spindle.
What should the throttle switch read with the throttle open?
With the throttle closed, the ohmmeter should read infinite (∞). With the throttle wide open the ohmmeter should read zero (0) ohms. The switch in resistance should occur just before the throttle reaches full open. If reading at the DME plug are unsatisfactory, the test should be repeated at the switch.
Where is the throttle position switch in Pico auto?
Go to the drop-down menu bar at the lower left corner of the Waveform Library window and select, Throttle position switch. The throttle position switch signals the movement and position of the throttle valve to the Engine Control Module (ECM). The switch unit is installed at the throttle housing and attached to the throttle butterfly spindle.
Can a faulty throttle position switch cause poor running?
A faulty throttle position switch (TPS) can result in a number of poor running problems. Because they can result in such a large number of problems, faulty switches often go undiagnosed.
The throttle position switch signals the movement and position of the throttle valve to the Engine Control Module (ECM). The switch unit is installed at the throttle housing and attached to the throttle butterfly spindle.
How can I test the throttle position sensor?
Check the manufacturer’s pin data for the fuel injection Electronic Control Module (ECM) throttle position sensor connection terminal. Back-probe the correct multiplug pin with the Back-pinning Probe as in Figure 2. Ensure that a good connection is made through to the wire or terminal and the probe has pierced through the wire and plug insulation.

How does the throttle position sensor ( TPS ) work?
An excessively high voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM). Electric Throttle Control Actuator consists of throttle control motor, throttle position sensor ( TPS ), etc. The throttle position sensor responds to the throttle valve movement. The throttle position sensor has the two sensors.
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.
How can I check the throttle position on my car?
Slowly, move the throttle through its full range of movement from its “closed” position to its “full open” position, while observing the digital readout on the DMM. It should increase or decrease steadily and evenly as the throttle linkage is moved through its full range.
What does the p2135 code on the throttle mean?
The throttle position sensor is located on the throttle body and once it fails, code P2135 may get triggered. What Does the P2135 Code Mean? Diagnostic trouble code (DTC) P2135 stands for “Throttle/Pedal Position Sensor/ Switch A/B Voltage Correlation.”
