5-GAS FAILURE ANALYSIS
This manual covers failures of 5-gas tailpipe tests whether you’re performing a state emissions inspection test or are just using a gas analyzer to diagnose a drivability or code complaint. While examples are from emissions test failures in California, you’re allowed to use a 5-gas analyzer everywhere. It’s an underleveraged tool because the gas relationships can get confusing, but we’ve focused on one factor (Lambda) to help you create the best possible cause list and quickly trim it from there.
The manual includes our unique flow charts for determining whether you have a fuel control or emissions control fault, and for eliminating possible causes from there. Also included are the examples, case studies and explanations from the webinar.
