flick your key on and off 3 times really fast the gauge cluster will read codes starting with a p write down the codes and look them up also you can temporarily get rid of the check engine light by disconnecting the negative battery cable and turning your key a couples times with the battery still disconnected this will get rid of the light for about a day or so but the problem causing the check engine light will need to be fixed to get it to go away permanantly....
(possibley) but most likey NO
If the light is on, it will need checked and diagnosed.
That is the check engine light.
No, it will not interchange.
yes it will, only a few mods will need to be done
Yes there is no difference in the two years 2001 was a carry over from 2001.
no a 2001 dodge neon motor will not work in a 2000 neon
No, The neon was revamped in 2003, with updated engines and chassis changes. As a Chrysler mechanic, the 2000 dodge neon 2.4L DOHC is the best. That will fit in a 2001 also.
no the light will not come on. i thought the same thing until i was almost right empty. i found that out when it over heated
You will need to get the cause of the check engine light repaired.
YesYes
Yes. The Dodge Neon has an interference engine.
