Top 10 2003 Dodge Neon Questions & Answers

I replaced the lower passenger side engine mount and the vibration is still there but a bit less vibration. The lower passenger mount was worn out. I was told by the Dodge service dept that it takes 5 hours to change the main hidden engine mount which is mid way up the passenger side of the engine. That main hidden mount cost 75.00

To get to it you would have to remove the wheel, inner fender plastic work, windshield washer fluid tank, and etc.

Don't delay on this. Take the vehicle in and have the oil pressure sensor checked. It could be just the sensor or it could be something more serious. A drop in oil pressure could lead to catastrophic engine failure.

Hay i'm back today I fixed the vibration and noise problem 01-10-2009 I removed and replaced that what Dodge calls the rear engine mount the one that is through the frame rail on the passengers side. acording to the Hayes service manual it dident seem diffacult but I was wrong the manual does not tell all , the engin has to be completly free so you can push back the engine toward the drivers side to give you enough room to pull out mount from frame rail took me between 3&4 hrs I'm a industriar truck Tech by trade and had all the tools nessary to do the job call me if you want here is my home phone num. 850-971-0085

the computer may need to be reflashed. if it is running then it is not a bad sensor. either of those being bad would cause it not to run.

Ok here is a simple question, has any one checked the battery connections? if not do so, remove the Battery ends and use a wire brush to clean the battery lugs and cable ends, if every thing is corroded use a mix of baking soda and water to remove the corrosion, while you are at it make sure the other near by connections are good, I hope this helps

You dont have to pull the tranny to fix this. Some so called "experts" on here shouldnt be giving advice if they dont know. The solenoid pack is located in the front the transmission just below the air filter and in front of the input speed sensor you just replaced. Unbolt the connector with a 10mm socket then the bolts connecting to the tranny. Replace with a new one 140 bux or close(get a new one). Installation is vice versa. Easy fix for any person who is mechanically inclined. Always get a second or third opinion when asking a thousand dollar question on any website. Some people think they know....but they dont.

I'd recommend Preston antifreeze, manufacture recommends a 50-50 ratio of antifreeze and water

The fuel pressure for that car would 53 to 63 psi. Anything in between 53 and 63 psi is good. Hope this will help you.

P0340 - Camshaft Position Sensor Circuit Malfunction
This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
Hard starting or no start
Rough running / misfiring
Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
a wire or connector in the circuit could be grounded/shorted/broken
the camshaft position sensor may have failed
the PCM may have failed
there exists an open circuit
the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
Visually inspect all the wiring and connectors in the circuit
Check for continuity in the circuit wiring
Check the operation (voltage) of the camshaft position sensor
Replace the camshaft position sensor as required
Check the crankshaft position circuit as well
Replace circuit wiring and/or connectors as required
Diagnose/replace the PCM as required


Hope helps.

The dome lamp receives power from the 10 amp micro fuse located in the Power Distribution Center (PDC) on the M1 circuit. This circuit is HOT at all times. The ground path for the lamp is provided in two different ways.

One way is through the door ajar switches. Circuit M2 connects to all the door ajar switches from the dome lamp. The switches are case-grounded to the body. When a door is opened, the plunger in the switch closes, completing a path to ground.

The second ground path is through the headlamp switch. Circuit M2 is spliced in with the door ajar switches. When the operator turns the headlamp switch to the dome lamp ON position, a ground path is provided through the switch on the Z1 circuit. This ground terminates at the instrument panel left center support.

The time delay relay is used to allow a time-ON function for the ignition switch lamp. Power for the relay is received on the M1 circuit from the 10 amp fuse located in the Power Distribution Center (PDC ).

When a door is opened, or the headlamp switch is moved to the dome lamp position, a ground path is provided for the relay on the M2 circuit. This energizes the relay, closing the contacts. When the relay contacts are closed, power is provided through the relay to the M50 circuit.

The M50 circuit supplies current to the ignition switch lamp in the steering column. Ground for the lamp is provided on the Z3 circuit. This circuit splices with the glove box lamp, the ash receiver lamp, and the PRNDL lamp. The Z3 circuit terminates at the instrument panel left center support.

So, I would check the time delay relay since it supplies power to the circuit. Also, check for a good ground at the instrument panel left center support.
