What should my throttle position percentage be?
Press down on the gas pedal very S-L-O-W-L-Y until the throttle is all the way open. You should see the percentage of throttle opening gradually increase to 100 percent at wide open throttle. If the TPS has a worn spot, most likely it will be between 0 and 20 percent throttle opening.
What does code p0122 on the throttle body mean?
What Does Code P0122 Mean? The throttle position sensor (TPS) is located on the throttle body. It is a type of variable resistor which changes its resistance value according to throttle position. As the throttle is opened, the voltage reading goes up.
What is the diagnostic code for throttle pedal position sensor?
P0122 is a diagnostic trouble code (DTC) for “Throttle Pedal Position Sensor/Switch (TPS) A Circuit Low Input”.
Why is my throttle position sensor too low?
As a generic powertrain code, this error message refers to many OBD-II compatible vehicles. Primarily, this code relates to the throttle position sensor and its voltage. When notified of this error, it is safe to assume that the A sensor is reporting voltage that is too low, likely between 0.17 and 0.20 volts.
What happens when the throttle gets stuck in an open position?
When the throttle gets stuck in an open position than your vehicle will receive too much air and cause it to have a high or fluctuating idle. What are signs of a bad Throttle Position Sensor? Acceleration issues: A bad TPS may cause all sorts of power issues. Your engine may start up but it will have little to no power and it causes it to shut off.
What Does Code P0122 Mean? The throttle position sensor (TPS) is located on the throttle body. It is a type of variable resistor which changes its resistance value according to throttle position. As the throttle is opened, the voltage reading goes up.
What is the error code for throttle position sensor?
If the module detects that the sensor is operating outside of a predetermined range, error code P0121 will be set. A throttle position sensor operating outside of a predetermined range can trigger code P0121.
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.
What’s the lower voltage limit for code p0122?
Depending on your vehicle, your TPS lower output voltage limit should be around.17 to.20 volts, and if the ECM detects that it has dipped below that, then it will trigger Code P0122. What Are the Symptoms of Code P0122?
