Question about 1996 Chrysler Town & Country

1 Answer

I have a Chrysler voyager 2,5 td 1996, with a bosch vp36 , I have already changed the injector n1, fuel filter , mass air flow, air filter,turbo actuator, checked the wires of the brakes, checked the intercooler pipes,checked for trouble codes(none),checked the egr valve it was fine even so I blocked the air passage trought the valve just in case,and after all of this it runs the same. The van runs fine and revs well till it reaches 2000rpm, after that it loses power like hitting a wall of air, the turbo starts to spin but at 2000rpm slows down and all the power goes away. Other simptoms is that when in idle after some minutes it starts to cof cof cof, (i dont know the word),so I disconnected the injection pump timing solenoid and the simptoms goes away, works fine at idle. another simptom is when I start the engine the trootlle pedal never works at the first push only at the second time. So I would like to know if its possible that the problem is the timing solenoisd that is broken . I have this problem for alot of months and I cannot see other problem that this,

    Hi, Thanks , I,ve already check in the past for the resistence and it mesures 15 ohms, if I disconnet the timing solenoid wires the idle goes fine , if they are connected after a minute or two the car starts with a rought idle and smoke, after changing the fuel filter this simptom got very bad . either way with or without the wires connected at 2000 rpm it wont revs. A guy from a bosch dealer told me maybe the fuel pump is a little delayed but I have to raise some funds before going in a bosch garage because it will be very expensive.
    Also the car is consuming alot fuel 12 litres per 100Km, it has no leaking and I dont see more smoke than the usual in a diesel car .

    Hi, yes I get 12 volts when the car is on idle, the bosch dealer told me that the pump works advanced with the solenoid disconected and when theres power it delays the pump, thats why he says that the pump should be a little more delayed than usual. according to what he says at idle the pump works with the solenoid on power putting the pump in normal advance and when the rpm rises it disconnects the solenoid putting some advance in the pump.So if the pump is more delayed than usual, at idle with the solenoid conected it gives me a rought idle and when I start to drive the rpm rises and the advance goes to normal when it should be with a certain advance. But if it works that way I dont see diference when I hit the 2000rpm, because theres always a lack of power. The only thing I see is that with the solenoid disconected the idle goes fine .

    I had the same problem. In the end - and it was a long and painful diagnosis process - I found out that it was the fuel timing solenoid. Once it was replaced it went back to normal.

The resistance for that selenoid should be about 15 homs

    Are you geting 12v on the timing solenoid wire conector?

03 Nissan Altima showing codes P0304,P0102,P0154,P0113 what are they and how do i repair the problems.


Hi Chris.

p0304 = Number 4 Cylinder Misfire Detected

Faulty spark plug 4
Clogged or faulty fuel injector 4
Faulty ignition coil 4
Fuel injector 4 harness is open or shorted
Fuel injector 4 circuit poor electrical connection
Ignition coil 4 harness is open or shorted
Ignition coil 4 circuit poor electrical connection
Insufficient cylinder 4 compression
Incorrect fuel pressure
Intake air leak

The P0304 code means that the cylinder 4 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 4.


p0102 = Mass or Volume Air Flow Circuit Low Input

Faulty mass air flow sensor
Intake air leaks
Dirty mass air flow sensor
Dirty mass air filter
Mass air flow sensor harness is open or shorted
Mass air flow sensor circuit poor electrical connection

Before replacing the mass air flow sensor, try replacing the air filter and cleaning the air flow sensor with low compress air or mass air flow sensor cleaner.
Reset code and drive vehicle.
If the code comes back, it may be necessary to replaced the mass air flow sensor.


p0154 = O2 Sensor Circuit No Activity Detected Sensor 1 Bank 2

Faulty Front Heated Oxygen Sensor Bank 2
Front Heated Oxygen Sensor Bank 2 harness is open or shorted
Front Heated Oxygen Sensor Bank 2 circuit poor electrical connection
Inappropriate fuel pressure
Faulty fuel injectors
Intake air leaks may be faulty
Exhaust gas leaks

Replacing the Front Heated Oxygen Sensor Bank 2 usually takes care of the problem.


p0113 = Intake Air Temperature Sensor Circuit High

Faulty Intake Air Temperature (IAT) sensor
Dirty air filter
Intake Air Temperature (IAT) sensor harness is open or shorted
Intake Air Temperature (IAT) sensor circuit poor electrical connection

The Intake Air Temperature (IAT) sensor is built into mass air flow sensor or in some vehicles mounted to the air filter duct housing. The sensor detects intake air temperature and transmits a signal to the Engine Control Module (ECM).The temperature sensing unit uses a thermistor which is sensitive to the change in temperature. Electrical resistance of the thermistor decreases in response to the temperature rise. The Intake Air Temperature signal is used as an input for various systems in the vehicle.



Hope this helps

Chrysler voyager se td 96 turbo problem?


Check for a hole in the rubber piping/hose coming from the turbo to the engine throttlebody. It is very common for the hose to get oil on it and that weakens the rubber and pops a hole in it. The smoke when you start it is also common as that engine has valve guides that get worn and the engine oil makes its way into the cylinders after running a while and sitting for at least 3-4 hours. Check that hose for a hole or to see if it came disconnected from the turbo or throttlebody. good luck

2004 jetta tdi, has engine miss & lack of power, has p0101 present, if unplugged has less power, but misses less, already cleaned extremely clogged egr valve, changed engine oil/filter, checked maf...


Running rough?? If i took a guess I'd say there's a faulty injector. Does it smoke like hell ?? Does it also miss at idle?- If so get a line wrench and a rag handy. Start the car and while idling wrap the rag around the base of the fuel line connector on injector 1 and crack it just a bit until fuel comes out. It might spray, thus the rag. If the miss gets worse, that ain't the injector to blame. Continue with the other 3. If you crack a line and there is no or very little change in the miss then you found the guilty party.

On a long shot it could also be a stuck valve.

Did that get it?? It sounds like an issue other than MAF but.... get a multimeter and try probing the connecter to the MAF. When you find out what it is , please let me know. I'm curious

1996 MERCURY GRAND MARQUIS WITH OCCASIONAL SLUGGISHNESS ON ACCELERATION AND SEEMS LIKE IT MAY BE USING MORE GAS THAN USUAL. HAS BEEN WELL TAKEN CARE OF, REG. OIL CHANGES, NEW FUEL FILTER 2 YRS AGO-DR


I would use 10W40 in the 96 and 5W20 or 30 in the 2002.

For the 96 with sluggishness, you need to gently clean the MAF sensor wires with carb cleaner and a toothbrush. It is in the air intake tube. After cleaning, disconnect the battery for 1/2 hour, then reconnect so the computer can relearn the clean sensor. Drive for 10 miles, it will run rough until it relearns.


Section 03-14: Engine Controls, Electronic 1996 Town Car, Crown Victoria, Grand Marquis Workshop Manual
DESCRIPTION AND OPERATION Mass Air Flow (MAF) Sensor The mass air flow sensor (MAF sensor) (12B579):
  • is mounted on the corner of the engine air cleaner (ACL) (9600).
  • uses a hot wire sensing element to measure the amount of air entering the engine; air passing over the hot wire causes it to cool.
  • sends out an analog voltage signal to the PCM (12A650) to determine the intake air mass. The PCM will then calculate the required fuel injector pulse width to provide the desired air/fuel ratio.
The mass air flow sensor hot wire sensing element and housing are calibrated as a unit and must be serviced as a complete assembly.

1996 Altima cranks, won't start


First, never use starting fluid on a gasoline engine. Check for dirty air filter, then check for Mass air flow sensor (Fault code) . This sensor controls fuel mapping, bad signal here will cause over fueling (black smoke) also called loading up (rich). Stopped up Air filter will affect Mass air flow. Perform OBD II test to prevent buying unneeded parts. Also delete stored codes.
