Sensor And Harness Verification by Comptek, Inc.
New Federal Emissions standards are causing many automotive companies to redesign their powertrain packages to provide better fuel economy and fewer pollutants. As a result, many powertrain subsystems and devices are becoming more sophisticated. This was the case with one manufacturer of exhaust systems who was chartered with the requirement to test and verify electronic components that were now required as a part of the exhaust assembly.
The manufacturer was required to verify the functionality of temperature probes and pressure transducers that were mounted to the exhaust assembly and connected by a common wire harness. A pressurized leak test was also performed on the part.
Comptek used itís computer based controls expertise to deliver a simple and cost effective system that would plug into the harness connector and test the harness and electronic devices for continuity and functionality. The computer based system was simple and easy to use for plant floor assembly personnel. The system was configured to run functional tests on various exhaust assemblies and save the performance results to a database. Engineers could query the database to determine failure trends in their assembly process.
