Question about 2004 Lincoln Navigator

Open Question

PRNDL error, no park assist error message

Error message/warning bell occurs frequently. Truck starts and seems to run fine. Brought to dealer to diagnose and they replaced park assist module first, followed by Powertrain Control Module. Neither has fixed this issue. Anyone help would be appreciated.

Sounds like a dealer only part. Sorry. There are other routes you can take with these vehicles. you can change out the air bag suspension with regular shocks and struts.

SOURCE: Po304 cylinder 4missfire on Lincoln navigator

for p0304 the possible solutions:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
I know this tool is helpful for your car.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

This is a devious problem which could lie anywhere. So many things not functioning would perhaps be a ground problem. Maybe take some extra care in cleaning the battery terminals, check if the ground wire is connected to the chassis. Do you have rodents in your area? Maybe they nibbled some wire somewhere?

Volvo V-70 drivetrain & electronics faults

I suspect you have some loose connections or shorts in the wiring harness. I've had similar strange things happen with an Olds Bravada. Various transmission shifting problems, faults, etc. that all seemed to come from the engine's computer system getting incorrect voltages and readings due to wiring faults/shorts.

When turning the key to start the car, 4 out of five times car wont turn over, starter is fine, battery fine, when i put the car in neutral, it will turn over, after it has run, the problem seems to...

If the engine will always crank over normally when the transmission is in Nuetral but not in Park then you may have a failing transmission mounted Park/Nuetral safety switch. [This switch may also be called a Range position switch or a PRNDL switch] If the problem will occur equally when in Park or Nuetral then you would need to test to see if the starter solenoid control wire is actually being powered up when the key is in the crank position and follow the circuit back to find the cause of the problem. Good luck, hope this helps.

You're shifter indicator appears to need attention. The PRNDL = Park - Reverse = Neutral - Drive - Low
These are the gears. You need to have a high end electronic pc test and see what error code it is 'throwing'

PRNDL error, no backup aid

i think the computer is telling you that it is not recognizing what gear you are in as you can only start the vehicle in park or nuetral. thats the best i can do for you sorry
