This guide is for automotive technicians and DIY mechanics who need to test and diagnose oxygen sensor issues. The Draper 24708 allows for testing of lambda/oxygen sensors, both heated and unheated, by simulating rich and lean mixtures. It features an LED display for monitoring the sensor signal, but it requires a separate 9V battery for operation.

This tester is designed for Zirconia and Titania lambda/oxygen sensors, accommodating 1 to 4 wire configurations, both heated and unheated.
No, a 9V battery is required and must be purchased separately.
Observe the LED display while simulating rich and lean conditions. A functioning sensor will show a crossover signal on the display.
The wire piercing clamp provides a quick and easy way to connect to the positive wire of the oxygen sensor without cutting or stripping the wire.
No, this tester focuses on simulating rich and lean mixtures to check the sensor's response and does not cover all possible failure modes.
Check the 9V battery and replace if necessary. Ensure the battery terminals are making proper contact.
Check the connections to the oxygen sensor. Ensure proper wiring and that the sensor is receiving power.
Verify the sensor type compatibility and ensure proper connection to the sensor's wires.
