Using a wideband sensor in a permanent installation

摘要

As a test, we substituted a wideband sensor for the narrowband sensor in a 2004 Holden Astra. The S-curve output from the Wideband Controller was then fed to the car's ECU (in place of the output from the original sensor). This worked OK and no error codes were produced by the ECU. However, we did have to keep the heater circuit to the original narrowband sensor connected to achieve this result.
