Question about 2000 Ford Crown Victoria

1 Answer

Hesitation and stumbling.

Replaced coil on plug ignition coils, new spark plugs, new crankshaft and camshaft position sensors, removed and cleaned all 8 fuel injectors and double checked all wires and plug-ins.
Runs fine with plenty of power until engine reaches operating temperature then begins misfiring. Reads Code 300 on EBDII (Random/Multiple Cylinder Misfire). Looking to replace the EDIS (Electronic Distributorless Ignition System), however this module is not where it is on older models (Driver's side fender). Cannot locate it period. Any help would be greatly appreciated.

Before you do that, check which thermostat it has in it, if it has one that is letting it get too warm or not completely up to temp when the computer think it should be, it would cause this. My 2000 crown vic did the same thing and thats what it was.

Do a 2004 Envoy SLT 4.2L have a Ignition Module?


Crankshaft position sensor,cam sensor . your vehicle should have coil on plug , a coil at each spark plug !
Ignition Coils
Each ignition coil has an ignition 1 feed and a ground. The PCM supplies an ignition control (IC) circuit. Each ignition coil contains a solid state driver module as its primary element. The powertrain control module (PCM) signals the coil driver to initiate a firing event by applying a signal to the IC circuit at the appropriate time. When the signal is removed, the coil fires the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.
During normal operation the powertrain control module (PCM) controls all ignition functions. If either the crankshaft position (CKP) or camshaft position (CMP) sensor signal is lost, the engine will continue to run because the PCM will default to a limp home mode using the remaining sensor input. As mentioned above, each coil is internally protected against damage from excessive voltage. If one or more coils were to fail in this manner, a misfiring condition would result. Diagnostic trouble codes are available to accurately diagnose the ignition system with a scan tool.
If a crank sensor is replaced a Crankshaft Position System Variation Learn must be done and a scan tool is need to do this.

I have a p2323 code and replaced the spark plugs. I pulled the battery cable and after a week the code came back. What could be causing this.


P2323 Dodge - Ignition Coil Secondary Number 8 Circuit Condition - Faulty spark plug or coil boot
- Faulty Ignition Coil 8
- Ignition Coil 8 harness is open or shorted
- Ignition Coil 8 circuit poor electrical connection
Possible symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine may be running rough

P2323 Dodge Description
The ignition system is controlled by the Powertrain Control Module (PCM) on all engines. Each cylinder is equipped with 1 dual-output coil. Meaning one coil mounts directly over one of the dual spark plugs for 1 high-voltage output.
Battery voltage is supplied to all of the ignition coils positive terminals from the ASD relay. If the PCM does not see a signal from the crankshaft and camshaft sensors (indicating the ignition key is ON but the engine is not running), it will shut down the ASD circuit.
Base ignition timing is not adjustable. By controlling the coil ground circuits, the PCM is able to set the base timing and adjust the ignition timing advance. This is done to meet changing engine operating conditions.
The PCM adjusts ignition timing based on inputs it receives from:
- The engine coolant temperature sensor
- The crankshaft position sensor (engine speed)
- The camshaft position sensor (crankshaft position)
- The manifold absolute pressure (MAP) sensor
- The throttle position sensor
- Transmission gear selection

I needto know how to replace a Crankshaft postion sensor A circuit


      • The sensor is mounted in a fixed position in the engine block. The tip of the sensor protrudes into the crankcase at a distance of 0.05 plus or minus 0.02 inch from the crankshaft.
      • A crankshaft adjusting tool may be used to check these rings
      place the tool on the pulley extension surface and rotate the tool around the pulley.
    • If any blade touches the tool, replace the pulley.
  • Inspect the trigger wheel behind the crankshaft pulley and the sensor for damage.
  • If the engine misfires all the time or on acceleration only, test the following components:
    • Engine compression.
    • Spark plugs.
    • Spark plug wires.
    • Ignition coils test for firing voltage with a test spark plug.
    • Crankshaft sensor.
    • Fuel injectors on multiport and sequential fuel injection systems. To remove the crank sensor
  • Disconnect the wiring harness.
  • Unbolt the sensor mounting bolt.
If the crankshaft timing sensor or the camshaft reference sensor is removed, follow this procedure when the sensor is replaced:
  • Thoroughly clean the sensor tip and install a new spacer on the sensor tip. New sensors should be supplied with the spacer installed.

Timing the cams and crank with a belt


  1. Note: Electronic Ignition engine timing is entirely controlled by the PCM. Electronic Ignition engine timing is NOT adjustable. Do not attempt to check base timing. You will receive false readings.

The CKP sensor is used to indicate crankshaft position and speed by sensing a missing tooth on a pulse wheel mounted to the crankshaft. The CMP sensor is used by the COP Integrated EI System to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.
  1. The PCM uses the CKP signal to calculate a spark target and then fires the coil pack(s) to that target shown in Figure 51. The PCM uses the CMP sensor not shown in Figure 51 on COP Integrated EI Systems to identify top dead center of compression of cylinder 1 to synchronize the firing of the individual coils.
  1. The coils and coil packs receive their signal from the PCM to fire at a calculated spark target. Each coil within the pack fires two spark plugs at the same time. The plugs are paired so that as one fires during the compression stroke the other fires during the exhaust stroke. The next time the coil is fired the situation is reversed. The COP system fires only one spark plug per coil and only on the compression stroke.

    The PCM acts as an electronic switch to ground in the coil primary circuit. When the switch is closed, battery positive voltage (B+) applied to the coil primary circuit builds a magnetic field around the primary coil. When the switch opens, the power is interrupted and the primary field collapses inducing the high voltage in the secondary coil windings and the spark plug is fired. A kickback voltage spike occurs when the primary field collapses. The PCM uses this voltage spike to generate an Ignition Diagnostic Monitor (IDM) signal. IDM communicates information by pulsewidth modulation in the PCM.
  1. The PCM processes the CKP signal and uses it to drive the tachometer as the Clean Tach Out (CTO) signal.

2.5L V6

The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by a pulse former within the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition timing is determined by the powertrain control module in response to engine operating conditions based on stored data tables or maps. Once ignition timing has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 5, cylinders 4 and 3 and cylinders 2 and 6) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This ensures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.

The Coil On Plug (COP) Integrated EI System uses a separate coil for each spark plug and each coil is mounted directly onto the plug. The COP Integrated EI System eliminates the need for spark plug wires but does require input from the camshaft position (CMP) sensor.
