Given the robust nature of today's emissions control components, it is entirely possible for an individual component to P1B89 malfunction without leading to an immediate increase in emissions at the tailpipe. In such cases, other components (like the catalyst) can temporarily compensate for the part that is broken however, these other components can only do double duty for so long before they, too, begin to malfunction.
