You are getting a fault message from the PCM that the wrong ignition key was used. This is part of the vehicle's onboard security system. This is part of the immobilizer system.

SOURCE: what is code 1494 mean for 2001 dodge neon

P1494 Leak Detection Pump Switch or Mechanical Fault
Part of the early evaporative emission system. (Fuel tank fumes)

It’s there to allow the computer to run an integrity test of the fuel tank, lines and carbon canister’s ability to contain all of the fumes coming from the tank and all line associated with the system.
The code could be set for a number of reasons such as a faulty gas cap, cracked vacuum lines, solenoids & vent valves stuck to the pump itself.
It can be a very difficult fault to cure being it doesn’t take a very big leak anywhere in the system to set the code and that’s if it’s a leak and not an electrical or mechanical fault.

SOURCE: Engine codes for 2001 Chrysler Sebring P0442 455 and 1685

PO442 means you have a small leak in your EVAP system. Most common cause is a bad gas cap, replace the gas cap with a factory gas cap,after market fail or does not conform to the OEM EVAP system. Other cause would be small leaks in the EVAP vacuum lines. P0445 is also related to the EVAP system and has detected a large leak in the system. Start with the gas cap as mentioned above. P1685 Is an issue with the ignition not recognizing the ignition keys and the car's ignition immobilizer my activate leaving the car not being able to start. That's going to have to be a Dealer repair. Good luck and hope this helps.

Code error for O2 sensor?


Code 21 the check engine light will flash 21 times cycle the ignition key ON-OFF-ON-OFF-ON within 5 seconds. To cycle the ignition key ON means to turn it only as far as it takes to get the radio to come on. It does not mean to turn the engine on.

Check engine light flashing a code. what does this mean


Please visit http://www.troublecodes.net/neon/

for clarification of your error code. But I strongly believe you fixed a low rated fuel pump.

also from your explanation you got code 55 which means no error code was recorded.

Rate this please.
