SKS-3057B diagnostic tools according to the working principle of all kinds of sensors in the Auto electronic control system. This equipment has the function of voltage, frequency, counts and duty cycle test. It can analyse accurately for the Voltage, frequency, pulses, duty cycle, sensor signal of throttle position sensor, air flow sensor, crankshaft and camshaft position sensor, manifold absolute pressure sensor, oxygen sensors, temperature sensors, knock sensor, etc. 

Functions:

1. Oxygen sensor fault diagnosis; 

2. Temperature sensor fault diagnosis;

3. Throttle position sensor fault diagnosis;

4. Manifold absolute pressure sensor fault diagnosis (Voltage and frequency signals);

5. Air flow sensor fault diagnosis;

6. Magnetoelectric sensor fault diagnosis;

7. Photoelectric sensor fault diagnosis;

8. Hall-sensor fault diagnosis.
