Prologics automotive sensor voltage probe

The Prologics Sensor Voltage Probe is a versatile automotive tool designed for testing and simulating sensor signals. It offers four key functions:

• Voltage Simulation: Outputs 0.5V–7.0V at 3A or 0.2V–7.0V at 150mA, emulating signals from various vehicle sensors.
• Voltage Measurement: Measures up to 70V DC with polarity detection.
• Resistance Measurement: Measures resistance up to 5kΩ.

Ideal for 12V and 24V systems with ECM/ECU, it can be used independently or alongside a diagnostic scanner. This tool helps technicians determine whether a fault originates from the sensor itself or from wiring and connectors during troubleshooting.

Features

• Fault Recognition via Error Codes: The probe allows simultaneous observation of sensor data while reading diagnostic scanner error codes.

• Sensor Signal Simulation: By simulating sensor output signals, the ECM/ECU response and efficiency can be evaluated.

• Typical Applications:

  1. Simulates outputs of Crankshaft Position (CKP), Camshaft Position (CMP), ABS, Wheel Speed (WSS), Coolant Temperature, Lambda (O2), MAF, MAP sensors, and more.

  2. Imitates sensor signals under different engine operating modes without removing the sensor unit.

• ECU Monitoring: During simulation, Live Data on the diagnostic scanner is monitored to assess ECU activity.

• Fault Diagnosis: Helps identify whether faults are due to sensor issues or wiring/ECU connections, reducing unnecessary part replacements.
