 If the resistance value is greater than 200kΩ , the LCD will

show “0L”.

There is also another way to prove continuity of connections to

ground or battery. Power up the connection using the power switch.

If the circuit breaker trips you know that you have a good solid low

resistance connection.

NOTE: You can use the probe tip to pierce the plastic insulation on

a wire. This means that you can test the circuit without

disconnecting anything.

3.3 Signal Circuit Testing

Once you extract a DTC from the vehicle and realize that

troubleshooting begins with some kind of sensor circuit, there is a

quick test you can perform to verify the code. Testing your sensor is

easy while using the tool.

For example, you suspect there is a problem with your M.A.P. sensor

circuit, then follow the procedure involved with testing this sensor:

 Set the tool in AC Voltage mode, using the probe tip with

chassis ground or the auxiliary ground lead.

 Connect vacuum pump to MAP sensor.

 Contact the probe tip to the MAP sensor positive terminal and

observe the LCD readings which should be a sine wave in

normal condition.

 Apply vacuum.

 Release vacuum and observe the LCD readings.（Figure 10）
