Re: 2001 dodge neon check engine lite is on code 1495...
P1495 Leak Detection Pump Solenoid Circuit Open Or Shorted Code P1495 is for the LDP solenoid circuit. (LDP-Leak Detection Pump). This is a system that seals off the evaporative system of the car and then pressurizes it with the LDP. The computer looks to see how long it takes to pressurize the system, (depending on fuel level) and then determines if the system is leaking. Emissions regulations require this to cut down on fuel vapours from escaping to the atmosphere.You will likely have to get a dealer to diagnose this, unless you can find a shop that has a manual and DRB scan tool.

a collection of codes like these need to be erased and then see which ones come back. this kind of thing often happens when the engine is cranked for a long time. 1- 1684; battery was disconnected 2- 0122; tps 3- 0320 engine speed malfunction 4- 0106 map 5- 1282 excessive injector pressure 6- 1495 leak detection pump
P0300 - generic misfire.
P0301 - misfire at cylinder 1 = the spark was not generated at some time at cylinder 1 P1494 - Evap Leak Detection pump pressure switch condition = the ECM detected the leak detection pump switch did not change after the solenoid was energized P1495 - leak detection pump solenoid circuit = the electrical circuit that commands the solenoid of the pump is interrupted You need to check the wiring to the solenoid and the solenoid itself, located under the driver's side in the cast cradle under the steering gear. A good expertise of car electrics is required for that, you will need a good repair shop.
this code refers to leak detection pump, you may have either a broken vaccuum line or a loose gas cap. if you are not familiar with leak detection you may want to get a shop involved, the price shouldn't be outrageous
if I am not mistaken that is the code for the engine temp sensor, it kind of works as a choke, it tell the computer the ngine temp so it can lean out the fuel mix. I think the code says engine is taking too long to warm up. A faulty sensor will read -40 C all the time
