  1. Connect Bosch Lambda Control Tester (KDJE-P600 ) to vehicle. Unplug oxygen sensor. Run engine until operating temperature is reached. Read and record voltage on tester with engine idling. Reconnect O2 sensor. Push 12-volt button on tester.
  2. Set engine speed to 2000 RPM. If engine is at operating temperature, voltage reading should not vary from previously recorded voltage by more than 0.8 volts. If reading is correct, lambda control is working and test is complete
