EFI Sensor 
Test Lead Kit

This complete kit of adapters is designed to make the job of testing EFI sensors a whole lot easier!  Properly functioning sensors are absolutely essential on any EFI equipped engine.  When your diagnostic tool indicates a sensor problem, your next task is to verify the sensor's operation with a digital voltmeter or sensor tester. Most voltmeters and sensors testers are supplied with insulation piercing test probes which punch a hole in the sensor wire's insulation providing a path for moisture and corrosion.  These test adapters clip directly onto the sensor and provide easy access to the sensor's voltage supply and output terminals without piercing the wires!  Save time and frustration.  The kit includes adapters for MAP, IAC, CTS, MAT, TPS and Knock sensors.
