The OBD system looks for broken or malfunctioning emissions control components and U1126, while tailpipe tests sample a vehicle's exhaust to see if it is above or below certain prescribed limits. Given the robust nature of today's emissions control components, it is entirely possible for an individual component to U1126 1999 1999 Ford Smax 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. In addition, OBD also monitors for U1126 1999 1999 Ford Smax and other malfunctions in the fuel system problems that traditional tailpipe tests were not designed to identify.
