This EM272 Lambda Tester and Simulator is designed to measure the crossover changes which occur in the closed loop control system. This device is able to indicate which wire on the lambda sensor the tester is connected to (ECU, open circuit, or ground). In addition, the presence of the heat generated from the supply voltage also can be identified by using this device. 

Main Features

  • Tests 1, 2, 3, and 4 wire sensors
  • Tests heated and non-heated sensors
  • Identifies which wire the tester is connected to, i.e. Ground, heater, or ECU supply
  • Rich or lean signal simulation to check ECU reaction
  • Wire piercing clip for easy connection
  • LED light path displays the crossover signals of the Lambda sensor
  • Low battery indication
  • Sealed control switches for a workshop environment
  • Durable ABS enclosure

Package Includes

  • Main Unit
  • Carrying Pouch
  • User Manual
