★ Top Answer
The B1342 code appearing on a Ford F-150 indicates a failure in the Electronic Control Unit (ECU). Typically, this code is accompanied by other issues or codes. The ECU is essentially a computer system that relies on a network of sensors to oversee various aspects of your engine's operation, such as fuel efficiency, emissions, and fuel injection. Among its crucial functions is controlling spark timing, which is responsible for igniting the fuel/oxygen mixture in your engine with precise timing. A misalignment in this process can lead to severe and possibly damaging engine misfires. If you experience intermittent engine stalling, especially during startup or while idling at stoplights, it might indicate a defective ECU.

My 2007 Ford F-150 initially had a problem where it would crank but not start. I decided to replace the engine control unit (ecu), and the truck was running perfectly for a few days. However, this morning I encountered the same issue of it cranking but not starting again, and I received error codes B1342 and C1300.
