This is an all in one sensor simulator. Rather than switching out sensors to verify an issue you can plug this simulator in and send a signal to the computer to see if the computer recognizes the change. Not only will this validate the computer thought process but it also verifies wiring and connection integrity. This simulator will mimic most automotive sensors from O2, camshaft, crankshaft, wheel speed and so on.
Manufacturer warranty: One year
