Code 16 means the PCM is offline or there is a communication issue between the PCM and PATS controller. Depending on model and year, the PATS controller could be in the instrument cluster, BCM or stand alone PATS module.

The Crown Victoria has a 4.6L engine first of all next how was the running condition before this happened? If it was normal no check engine light on and idling fine then check the emissions lines from the tank to the evaporative canister also check the idle air control valve hose this valve is metal and looks like a vacuum cleaner power head or a hammer head shark yes I said that you can go to rockauto.Com and look up the vehicle then the part to see what it looks like anyway also check the throttle body clean it with spray ///////now obviously I'm not there to see what's going on with the car and only you know how you went in the ditch there's a emissions line with a plastic fitting around the engine crossmember on the rear side of the engine and transmission this may have broken and is letting outside air into the system I know on a 97 it's there cause it happened to me might still be there but I'm not sure still all the lines and hoses must be checked under the car the emissions canister and valve is uder the trunk you ll see a metal cover over it with hoses going in it take the cover bolts out don't worry about the bolts there going to break from rusting out you can get regular bolts / nuts / washers to hold the cover on/////// also is the car driving in all gears and not slipping in and out of gear if yes good if not the shifter cable at the bracket on the transmission is separated from the cover and lug that holds it in place and this will make the transmission go in & and out of gear into neutral making the idle rpms go up and back down when it's in the right position if so you must replace the shifter cable it can't be fixed also check the motor mounts if you broke one the engine moved and is pulling on the cable from the gas peddle good luck stephen
No if it starts but you have to keep your foot on the gas to keep it running and then it dies when you take your foot off the pedal the fuel pump is working otherwise no gas at all if it was not working the throttle position sensor is bad the contact in the sensor is worn out at idle spot but when you first star it the sensor is in a different position and with your foot on the gas you can keep it running right racing like a normal engine but if no gas peddle it won't run if you just turn the key to start like normal but there's also a possibility that the idle air control valve is shot to both are on the throttle body you can look at them at rockauto.Com I'm assuming that your using premium gas and your throttle body is clean if not clean it out and see what happens before you spend $$$ on parts and check all your vacuum lines
There is a switch on the brake pedal lever that ties all of those components together. Most likely switch was hit with driver foot and jarred loose or broken.
Idea was to prevent someone from starting car or moving car without the drivers foot on the brake. Often brake lights will not light up. Fix that part and everything will release.
There are three fuse's for the instrument cluster , all located in the central junction box (fuse panel ) inside the vehicle ,under the dash !
Fuse # 14 a 10 amp , fuse # 23 15amp. and #6 15amp . Look behind right and left kick panel . But i don't think this is a fuse problem , gauge itself could be bad .
The Crown Vic has issues with the spark plug wires, replace them if the spark plug connector boot looks burned or has holes burned into it. Replace just one wire at a time!! Also do you have a check engine light? You should if your engine has a misfiring cylinder.
You can't by-pass this system. Try locking/unlocking the doors with the key fob. If that doesn't work, try locking/unlocking the drivers door with the key. If still no luck, try disconnecting the battery for a minute or so. Do you have another key you can try?
The best place to start is take it an have it checked for DTC'S -diagnostic trouble codes ! Not with a code reader ,as these just read OBD2 codes .Not Body control module codes >

if the drive belt is correctly fitted and tensioned the alternator should be charging....have it checked and, if necessary, replaced
I am assuming that all the charging components, such as the regulator, are integrated in the unit.
Also, have the specific gravity of the cells in your battery checked for health/condition...might be the battery is not holding a charge very well, could be a dead cell.
