THROTTLE POSITION SENSOR CIRCUIT HIGH VOLTAGE
Code 21 - Throttle Position Sensor (TPS) Circuit
The Throttle Position Sensor (TPS) provides a voltage signal that changes relative to the throttle blade. Signal voltage will vary from about 0.5 at idle to about 5 volts at wide open throttle. The TPS signal is one of the most important inputs used by the ECM for fuel
P0223 HONDA Throttle Position Sensor 'B' Circuit High Voltage
Jun 14, 2015The throttle position sensor has the two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the Engine Control Module (ECM) In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM.
Throttle Position Sensor (TPS) - Function - Failure - Testing
A potentiometer, however, sends a very low voltage to the (ECU) when the ignition is on but the throttle is off. It then increases the voltage as the throttle is increased, usually reaching a peak of 5 Volts when the throttle reaches its maximum.

P0123 OBD-II Trouble Code: Throttle Pedal Position Sensor
Throttle Pedal Position Sensor/Switch (TPS) A Circuit High Input What the P0123 code means P0123 is the generic OBD-II code which indicates that the Engine Control Module (ECM) has seen the TPS circuit A output voltage go above the sensor's expected voltage
P2138 Throttle/Pedal Pos Sensor/Switch D/E Voltage
Jun 07, 2016Voltage typically ranges from.5-volts at closed throttle to 4.5-volts at wide open throttle. If glitches or other inconsistencies are detected, suspect that the sensor being tested is defective. Some manufacturers require that the throttle body, throttle actuator motor, and all throttle position sensors be replaced together.
Part 1 -Throttle Position Sensor (TPS) Test (Ford 5, 5)
Jun 24, 2020The throttle position sensor gets 5 Volts and Ground from the ECM. As the engine in your pickup or van idles (and the throttle plate is closed), the throttle position sensor sends the ECM a voltage signal of about 0.9 to 1 Volts.
