Symptoms of a Bad Throttle Position Sensor
Symptoms of a Bad Throttle Position Sensor Fleas caused the Black Plague. A few misplaced carbon atoms sank the Titanic. Tribbles crippled the Enterprise. Sometimes, the smallest and most seemingly innocuous things can cause the biggest problems, and that certainly is true of one little sensor on top of your engine. These days, engines have become so utterly dependent on this simple sensor that many use it exclusively in place of the reliable old throttle cable. It doesn't take much going wrong in the throttle position sensor to cause a whole plague of issues -- possibly including a bit of unintended acceleration to warp speed. TPS Sensor Function At heart, a TPS sensor is effectively a dimmer switch. It's a "potentiometer," a kind of variable resistor that can increase or decrease the amount of voltage that makes it from one end of the sensor to the other. Inside the sensor is a crescent-shaped strip of material with a certain amount of resistance. A metal arm...
