Returning home from our summer in Anacortes, and Port Townsend the dashboard was showing a "Check Engine" light. It had become an intermittent problem with my Caterpillar 3126 since our May trip to Armitage Park Campground in Eugene, OR. The light was also accompanied by a noticeable drop in power.
Our SilverLeaf Electronics VMSpc software running on a laptop plugged into the Safari's diagnostic port was reporting:
ENG PID 1 43 UNKNOWN COMPONENT, Unknown Failure
Knowing that diagnosing this problem was beyond my knowledge and tools, I dropped the motorhome off at Peterson Cat in Portland, OR. Pro Tip: Always take photos of your rig whenever you bring it in for service just in case something unfortunate happens.
Problem Resolved
Peterson Cat diagnosed and solved the problem. During the Injector Solenoid Test, all six injectors passed but the #1 connector was found to be very loose. The overall wiring harness checked out OK. Petersons replaced the injector wiring harness for #1 (a short adapter that connects to the larger harness) and installed a new valve cover gasket. The Check Engine light has not returned since the service, and the engine's power has been restored.
