A good ground connection is also extremely important. C1178 2005 2005 Pontiac Montana engine problem because the presence of voltage at the panel harness won't make the panel work if there is a bad ground connection. Since the instrument cluster is mounted in a plastic dash, a separate ground wire or ground circuit through the wiring harness is usually needed to complete the power circuit. Refer again to the wiring diagram to find the ground path, and then check it with your ohmmeter. Do not use a self-powered test light because it cannot measure resistance (any resistance will lower circuit voltage).

Probably the biggest result of injector failure is due to the injectors having excessive return flow or back leakage.

The OBD system looks for broken or malfunctioning emissions control components and C1178, 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 C1178 2005 2005 Pontiac Montana 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 C1178 2005 2005 Pontiac Montana and other malfunctions in the fuel system problems that traditional tailpipe tests were not designed to identify.
