Throttle Position Sensor Simulation & Diagnostic | TPS Signal Simulation to Diagnose Engine ECM

In this video I explain how to simulate the throttle position sensors when there is a fault on the throttle body or there is limited engine RPM. When there is a throttle position sensor fault, it could be caused by throttle body, wiring or Engine Control Module. In the previous video, I explained how to test the sensor and wiring, but in this video I explain how to simulate the sensors output signals to see if this fault caused by ECM. This test will give you this certainty when you want to change the Engine ECM.
