Where is the vaccum located on 2005 dodge neon


Sounds like you mean the problem could be a leak in the EVAP system. The computer vents the gas tank to the vapor canister several times while you are driving.
The engine produces vacuum when it is running.
Do you have the actual trouble code ?

Check your vacuum lines, it sounds like one did not get reconnected correctly. When this happens you check engine to come on and will cause your engine's rpm's to rise.

Has code 0420


This code indicates that the catalytic converter is not functioning properly. This could be due to a poor state of tune and the poor running engine is overloading the cat to the point where it can't control the emissions, or the cat is simply worn out and needs to be replaced.

I have a 97 dodge caravan. the only code i have is from the check engine light. the code is 12,54,55. can anyone help me understand that code?


If it's a '97, go down to autozone and have them check your check engine light. This will give you an OBD code that you can google to find the actual problem.

P-0420


The definition of code P0420 Is Catalyst Efficiency. You may have an oxygen sensor problem or a catalytic converter problem. Your vehicle has 2 oxygen sensors. Check your oxygen sensors.If they are then you may need a catalytic converter. Depending on your mileage it may be covered under a Dodge emissions warranty. Have it checked by a certified garage first and in the meantime contact your local Dodge dealer and find out the emissions warranty most are 8 yr or 80,000 miles.

My 2003 dodge sx2.0 rt car has an engion light on and the code that is comming on in the dash display is p 0441


first inspect all the small vacuum lines connected to the intake manifold. The plastic lines are often the cause for this code, as well as the covered vacuum lines. Also look at the gas cap.is it tightened properly and check the inside seal of the cap is it cracked.if so replace it.

I have 2005 neon sxt keep having code po457 evap emmission loose cap /off replaced cap from chrysler ck eng light comes back on same code anybody have any suggestions


fuel cap is just one of the causes. Here are 2 others:
  • possible vacuum leak
  • NVLD switch is stuck or malfunctioning
NVLD switch communicates with your car's computer. A bad switch will throw a P0457 error code. Check for a vacuum leak 1st but if none is found, the NVLD switch should be changed.
Below is a link that explains more thoroughly what the module does; I do wish you the best of luck with your Neon and hope you found this information helpful. Take care!

Engine running at 1500 rpm to 3000 rmp when started but stays at 1500 at a red light when driving car stay at 2000 to 2500 rpm


Your problem is typical to a vacuum leak. Check all of the vacuum lines connected to the engine for proper connection, and make sure there are no cracked vacuum lines. If you don't see any vacuum hose problems you will need to check the intake for leaks. The easiest way to do this is to take a spray bottle full of water and spray it around the intake and intake hoses with the engine running. If there is a change in engine RPM's while spraying with water, inspect area for the source of the leak.
