temperature sensor (TA) air intake is a thermistor (resistor whose resistance depends on temperature). The resistance of the thermistor decreases as the temperature of the incoming air increases, as shown in the figure.
Turn on the ignition.
Measure voltage between 3 (red (+)) and 32 (black (-)) contacts.
If the voltage is in the range of 2-4 V, then the TA sensor is normal.
Otherwise, turn off the ignition.
Next, disconnect the 2-pin connector on the TA sensor.
Turn on the ignition.
Measure voltage between 3 (red (+)) and 32 (black (-)) contacts.
If the voltage is not approximately 5 V, then the control unit should be replaced and rechecked.
If the voltage is approximately 5 V, then the resistance between the two contacts of the TA sensor should be measured.
If the resistance is not in the range of 1-4Kom, then the TA sensor should be replaced.
If the resistance is in the range of 1-4 Kom, then you should measure the voltage between the Red contact (+) and mass.
If the voltage is approximately 5 V, then you should repair the open in the Black wire between the TA sensor and point G2.
Otherwise, the open or short circuit of the Red conductor between the TA sensor and terminal 3 of the control unit should be repaired.
