1983 Ford F 150 Eec3 Egnition Diagram

By | May 15, 2023

The 1983 Ford F-150 EEC-3 ignition system is a distributorless electronic ignition system that uses a crankshaft position sensor (CKP) and camshaft position sensor (CMP) to trigger the ignition coils. The EEC-3 system is more advanced than the previous EEC-2 system and provides better performance and fuel economy.

The EEC-3 system consists of the following components:

  • Engine control module (ECM)
  • Crankshaft position sensor (CKP)
  • Camshaft position sensor (CMP)
  • Ignition coils
  • Spark plugs

The ECM is the main control unit for the EEC-3 system. It receives signals from the CKP and CMP sensors and uses this information to determine the firing order of the spark plugs. The ECM also controls the fuel injectors and ignition timing.

The CKP sensor is located on the crankshaft and sends a signal to the ECM indicating the position of the crankshaft. The CMP sensor is located on the camshaft and sends a signal to the ECM indicating the position of the camshaft. These signals are used by the ECM to determine the firing order of the spark plugs.

The ignition coils are located on the top of the engine and are responsible for generating the high voltage needed to fire the spark plugs. The spark plugs are located in the combustion chambers of the engine and are responsible for igniting the air-fuel mixture.

The EEC-3 ignition system is a reliable and efficient system that provides good performance and fuel economy. If you have a 1983 Ford F-150 with the EEC-3 ignition system, it is important to keep the system properly maintained to ensure peak performance.

Here are some tips for maintaining the EEC-3 ignition system:

  • Change the spark plugs and ignition wires according to the manufacturer's recommendations.
  • Check the condition of the CKP and CMP sensors and replace them if they are damaged.
  • Clean the throttle body and intake manifold regularly.
  • Use high-quality fuel.

By following these tips, you can help to keep your 1983 Ford F-150 EEC-3 ignition system running smoothly and efficiently.
