SUBJECT:
Simulator Tool for Bosch Oxygen Sensors

MODELS:
All

Situation:




A new tool has been developed to systematically check the various operating functions of the Bosch oxygen sensor system. See operating instructions for details. The new simulator has been designed to easily test the oxygen sensor's

^ heating circuit (Test 1);
^ voltage output (Test 2);
^ DME control module - control circuits (Test 3); and
^ complete oxygen sensor connecting harness.

The simulator should be used if no obvious faults are determined in the oxygen sensor system (i.e., broken/chafed wires, poor connections, rattling, etc.), to determine the exact location of the defect and thus eliminating the need for "guesswork" when an oxygen sensor replacement becomes necessary.

Note:
Testing of returned oxygen sensors (under warranty) has shown a large percentage of non-defective sensors.

The new simulator is used in conjunction with a multimeter and a workshop emissions tester as outlined in the operating instructions.
