2000 Plymouth Neon Question: p0455
Answer #1joelburke26 from Joels Auto Service, February 23, 2011, 18:24Master
my scanner shows that as evap emissions leak(large leak detected) that would be tough to find unless you see large cracks or broken fuel lines,seperated evap lines and things of that nature.a mechanic with a smoke machine could find the leak and thats probably what you'll have to do to get it fixed.

P0455 - EVAP LEAK MONITOR LARGE LEAK DETECTED

Immediately after a cold start, with battery/ambient temperature between 40 °F - 90 °F and coolant temperature within 10 °F of battery/ambient temperature.
