sometimes when i take my foot off the gas pedal the rpm's in my car jump up, starts to rev real high. i have had the throttle body cleaned and aslo had the fuel injection system flushed. they ran a diagnostic on the car and found no issues with the sensors. the also reset the onboard computer. this helped with the high idleing in park but not with the sudden rev up when the gas pedal is released

Hi,how are you?From what you are describing,this is consistent with the throttle position sensor short circuiting at times as long as the sensor has not fully failed it generally will not throw a trouble code.
how much does it usually cost to have the throttle position sensor replaced
The sensor is about $70.00
The throttle position sensor is a rotating type variable resistor that rotates with the throttle body-s throttle shaft to sense the throttle valve angle. As the throttle shaft rotates, the throttle angle of the sensor changes and the ECM/PCM detects the throttle valve opening based on the TPS output voltage.
Hi,let meknow if you need further assistance,thank you.
