Lambda sensor tester and simulator
TSL-3 - DeltaTech Electronics (DTE)
The TSL-3 tester is used to diagnose the most common zirconia lambda sensors. It also serves to simulate the rich and poor fuel mixture. In order to test the lambda sensor first, it is necessary to locate the signal wire of the lambda sensor (preferably using the diagram) and next to connect it to (in parallel - according to the technical drawing), for example by means of the pin sensor or just the pin itself, the blue wire of the TSL-3 tester.
