What does error code P0351 for 2000 Ford Explorer?

Answer 1

This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD2 vehicle diagnostics. Although generic, the specific repair steps may vary depending on make/model. The COP (coil on plug) ignition system is what is used on most modern engines. There is an individual coil for each cylinder that is controlled by the PCM (powertrain control module). It eliminates the need for spark plug wires by putting the coil right above the sparkplug. Two wires are dedicated to each coil. One is a battery feed usually from the power distribution center. The other wire is the coil driver circuit from the PCM. The PCM grounds/ungrounds this circuit to activate or deactivate the coil.
