- Connect adapter cable between differential pressure regulator and multimeter. Start engine and bring it to operating temperature. Confirm that lambda control is working. Unplug connector from throttle valve switch. Bridge 2 leads on wiring to ECU.

) less than measured system pressure. If pressure reading is not correct, test control current to differential pressure regulator and test TD ignition signal.
