Measure 3-pin TPS sensor with MULTIMETER

The 3-pin TPS sensor can be checked with a multimeter in a few minutes.
With a multimeter on the scale of 5 kilo ohms we will proceed to measure the total resistance of the TPS sensor, it should mark a value of 5 kilo ohms.
If it marks a value close to zero it means that it is shorted, if the value is very high, 1 Mega Ohm or more then e; sensor is open. In either of these two cases it is necessary to change it.
If the first measurement of 5 kilo ohms is correct then we must move on to measuring the path of the sensor between the pin corresponding to ground and the central or signal pin.
To determine which is the ground pin, it is necessary to identify in the wiring which is connected to the chassis.
On the 5 kilo ohm scale and between pins 1 - 2 we should have an initial value of around 1 kilo ohm.
With the help of a large flat screwdriver we proceed to move the axis of the TPS sensor, simulating the acceleration of the car, we should notice that the resistance rises evenly to 5 kilo ohms.
If the resistance between pins 1 and 2 does not behave progressively and without jumps then the TPS sensor is damaged and must be replaced.
If the measurement between pins 1 and 2 goes to 0 ohms or a very low value, if the resistance rises to a very high value and then returns to a range less than 5 kilo ohms, it is indicative that the TPS sensor has a cut in the track and there is no choice but to change it.
