Passenger side coil pack has erratic output - driver side seems normal - is this the main computer ECM or PCM

This code could also mean the transistor inside the engine computer is fried . New PCM/ECM needed .

P2308 Dodge Description The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. When the ignition coil driver is switched on, current rapidly builds up to a maximum value, determined by the coil inductance and resistance. When the current is switched off, the magnetic field collapses which induces a secondary high voltage surge and the spark plug is fired. This high voltage surge creates a flyback voltage which the PCM uses as a feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2308 code sets when the PCM detects a short to voltage in the circuit.

P0350 - Ignition Coil Primary/Secondary Circuit Description: Each ignition primary circuit is continuously monitored. The test fails when the powertrain control module (PCM) does not receive a valid ignition diagnostic monitor (IDM) pulse signal from the ignition module (integrated in the PCM). Possible Causes:

• Open or short in the Ignition START/RUN circuit
• Open coil driver circuit
• Coil driver circuit shorted to ground
• Damaged coil
• Coil driver circuit shorted to VPWR

Diagnostic Aids: Use the 12-volt non-powered test lamp to verify START/RUN voltage at the ignition coil harness connector.
Check the coil driver circuit for open, short to VPWR, or short to ground. Application Key On Engine Off Key On Engine Running Continuous Memory Coil pack ignition testing GO to Pinpoint Test JC . Coil-on-plug (COP) ignition testing GO to Pinpoint Test JB . Without me testing , it's hard to say what you got going on ! Coil packs ? What engine does it have ? 5.4 L ? should have coil on plug ignition .

I looked up info for your vehicle, it shows coil on plug ignition, no coil pack, Is that correct?

The ecm or pcm is the computer. Am I misunderstanding your post?

The power scorce isn't the ECM .Test another coil for 12 volts key on run the configuration of the wires in side the connecters will be the same .Then see what is hot in coil B connector if you have the same voltage and tests the same then the coil pack is likely the problem but test the grounds on B and check the main wire OHMS before you start spending money

If it's a 2.2, its on the passengers side, mounted to the engine block just above the motor mount. It sits under the coil packs. If you meant PCM, its inside the truck passenger side, behind the glove box.

are you able to have the engine code read? for free at any autozone or advance auto parts store? sounds exactly like you have a bad computer,located on the passenger side at the kick panel where your right foot would be if you're setting in the passenger side seat.!1st i would check your ecm fuse located under the hood in the main fuse box on the driverside fenderwell,all good? then move towards the computer. thank you for choosing fixya.com!

If those three items are replaced and it still doesn't fire up, look for a possible computer problem.
Or, look for a broken wire or fuse for the ignition system.

Good luck on this repair.

1998 Ford Truck Expedition 4WD 5.4L EFI 8cyl

PCM Ford's Location:
* Ranger - behind instrument panel (cowl), center to both driver and passenger sides.
* Explorer/Mountaineer - behind instrument panel (cowl), (access from engine compartment dash panel) on passenger side to center of vehicle.
* All other F-Series, Expedition/Navigator - lower dash panel on passenger side.
* Excursion - lower dash panel on driver side.

The PCM is behind the glove box and has a big harness connector in the firewall that you access from the engine compartment.

REMOVAL & INSTALLATION



Fig. 1 The calibration number will be needed to order such parts as a replacement PCM, various sensors, and almost any emission control component. Typically this number is attached to a label found on the driver's door or the door pillar


1997-00 F-150, F-250, Expedition and Navigator



Fig. 2 Loosen the connector retaining bolt and remove the PCM connector



Fig. 3 Remove the passenger side front door scuff plate



Fig. 4 Remove the passenger side kick panel



Fig. 5 Remove the PCM bracket clip and remove the PCM

1. Remove the battery and the battery tray.
2. Loosen the connector retaining bolt and remove the PCM connector.
3. Remove the passenger side front door scuff plate.
4. Remove the passenger side kick panel.
5. Remove the PCM bracket clip.
6. Remove the PCM.
   

To install:

1. Installation is the reverse of removal.
2. Tighten the PCM connector retaining bolt to 36-44 inch lbs. (4-5 Nm).

Hope helps.

2 different 3.8's for that. Will send other picture as well, you pick what you have.

It sounds like you have a problem with your crank sensor or cam sensor!! You will have to take to a dealer that knows how to learn the crank sensore.. Yes it has to be learned into the computer.

Also there was a sevice bulletn on mising being that the intake valves needed to be replaced and reseated.

The transmission code is being sent because of the randome missing.. so it will not upshift into I think 4th (lockup). and the other is sent to torque because of the random miss also..

Solution!!!!!!! take to dealer and have them relearn crank sensor!!!

Hope this helps
