Default Throttle Position Sensor TPS resistance check


Symptoms. Starting failures when engine is at running temp, but outside air temperature is less than -10c. Idle will sometimes be so low at a stop sign, that the car will stall.

Using my multimeter, I tested the resistance between pins 2 and 3. At approx 1/3 throttle the resistance is infinite. Is the TPS toast?
