The Sensor Voltage Probe can perform four functions namely:
• Simulation of 0.5V ~ 7.0V (3A output).
• Simulation of 0.2V ~ 7.0V (150mA or 0.15A output).
• Volt measurement up to 70V DC with polarity check.
• Resistance ( ) measurement up to 5K

The simulated voltages output is mainly used to emulate the
signals generated by different types of sensors in the vehicle.
It can be used in all automobiles (12V/24V systems) with ECM /
ECU either independently, or very often it is used together with a
diagnostic scanner to distinguish faults whether that lies in the
sensor itself or related to the connection (connector or wires)
during troubleshooting phase.
From the reading of Error codes on the diagnostic scanner, faults
are recognized, as the sensors data which is imitated at the same
time by this probe were observed.
Through the simulation of the sensor output signals, the ECM /
ECU response as well as its efficiency can be estimated.
Typical Applications
1. Simulates vehicle sensors output signals of Crankshaft Position (CKP) sensor, Camshaft Position
(CMP) sensor, ABS sensor, Wheel Speed (WSS) sensor, Coolant Temperature sensor, Lambda (O2)
sensor, MAF, MAP, etc.
2. Imitates sensor’s signals at different working modes of the engine. This is done by simulating the
signals with this VR1 Probe without removing the sensor unit. During simulation process, the ECU’s
activities are monitored on the Live Data screen displayed by the Diagnostic Scanner.
In this way, we can determine the real cause of the fault whether it lies in the cables connected to the
ECU or at the sensor itself before any replacement of parts take place.
