Electronic Ignition (EI) System
The Electronic Ignition (EI) system consists of
- ten ignition coils.
- ten spark plugs.
- Crankshaft Position (CKP) sensor.
The EI system is a coil-on-plug ignition system which uses one ignition coil for each cylinder attached to the spark plug. The PCM receives a signal from the CKP sensor and sends low voltage signals to each of the ignition coils. The ignition coils turn low voltage signals into high voltage pulses which are passed through the spark plugs to ignite the compressed fuel and air mixture.
Crankshaft Position (CKP) Sensor
The CKP sensor
- is a variable reluctance sensor.
- is triggered by a 40-minus-1 tooth trigger wheel mounted on the crankshaft.
- provides base timing and crankshaft speed (RPM) to the PCM.
For removal and installation, refer to ELECTRONIC ENGINE CONTROLS .
Ignition Coils
The 10 separate ignition coils
- change low voltage signals from the PCM to high voltage pulses.
- produce the high voltage pulses to the spark plugs.
- are connected directly to each spark plug.
For removal and installation, refer to IGNITION COIL-ON-PLUG .
Spark Plugs
The 10 spark plugs
- change a high voltage pulse into a spark, which ignites the fuel and air mixture.
For removal and installation, refer to SPARK PLUGS .
Refer to the INTRODUCTION - GASOLINE MODELS .

Removal and Installation
- Remove the engine cover. For additional information, refer to «INTERIOR TRIM AND ORNAMENTATION»(/ford/econoline-e250/2012-2013/remont/exteriorinterior-trim/#interior-trim-and-ornamentation) .
- Remove the Air Cleaner (ACL) assembly. For additional information, refer to «INTAKE AIR DISTRIBUTION & FILTERING»(/ford/econoline-e250/2012-2013/remont/removal-installation/#intake-air-distribution-system-intake-air-filtering-system) .
- Disconnect the ignition coil electrical connector.
- Remove the bolt and the ignition coil. To install, tighten to 6 Nm (53 lb-in).
- To install, reverse the removal procedure. Apply dielectric compound to the inside of the coil boots.
Scheme 6
- Remove the ignition coil. For additional information, refer to «IGNITION COIL-ON-PLUG»(/ford/econoline-e250/2012-2013/remont/ignition-system/#engine-ignition-system-68l-e-series__ignition-coil-on-plug) .
- Remove the spark plugs. To install, tighten to 18 Nm (159 lb-in).
- Inspect the spark plugs. For additional information, refer to «ENGINE SYSTEM - GENERAL INFORMATION»(/ford/econoline-e250/2012-2013/remont/mechanical/#engine-system-general-information-e-series) .
- To install, reverse the removal procedure. Adjust the plug gap as necessary. Refer to «SPECIFICATIONS»(/ford/econoline-e250/2012-2013/remont/ignition-system/#engine-ignition-system-68l-e-series__specifications) for the correct spark plug gap specification.
