This code will not stall or no start of your engine, evap only work when engine is off, it is to reduce the fume your gas tank lets out to protect the o zone, but it will not pass Emission test, also could be some thing a small as your gas cap not sealing right.

P0455 P0442 codes 2001 dodge ram 1500

P0442 Means you have a small leak in your EVAP system. P0455 is a large leak.
The EVAP system prevents gas vapors from entering the air .
This code can be set by a leak in the lines or a clogged charcoal canister.
Most common reason is If you did not put your gas cap on all the way.
Hope this helps

Dodge Durango code shows 0051: where is Sensor 1/Bank 2? Where can I find a pix or diagram? Code also showsP0700 & P0455; what do these mean? Thanks.

Bank 1 is the same side of the engine as the number one cylinder. Bank 2 is the other side of the engine. Sensor one is always before the catalytic converter. Sensor 2 is always after the catalytic converter.

P0455 is an EVAP leak check the evap hoses for cracks/leaks.

P0700 is a generic code that lets you know you need to scan the transmission control module to see what codes are stored in it.

That last time I fixed this code it ended up being a leaking EVAP hose on top of the fuel tank. I had to drop the tank and put new sealant on the hoses to stop the leak.

I have a 2001 dodge ram with a 5.2 liter 318 engine. i checked my code & it came up as #P 0455. the problem i am having is when you first touch the gas, it has just a little bit of hesitation &...

P0455=EVAP Emission Control System Leak (Large Leak)

Possible gas cap fix, cheapest try first.

Check the gas cap thoroughly, the P0455 code your getting for the large leak isusually a bad gas cap.

Also check the lines on the canister tank,right underthe passengers side of the cab, there are two lines on top that will rotand fall off or get loose enough that they will cause that problem.

You can also check on the passengers side fender well under the hood andlook at the elbows on the EVAP valve that has the hoses that run downto the canister tank, chances are one of them is loose or bad.

Best to get a factory service manual to have handy through all of this. has complete factory ones for around 20 bucks. Here is a link 2001 Dodge Ram Service Manual.

2001 Ram 3 error code come up, are there related? P0123 P1596 P0455 Thanks , I just bought the truck 2 months ago and at that time it was emmission tested and it passed. Im in ontario!!!

123 is TP sensor , 455 is leak in evap system, quite often bad gas cap seal or not on tight, if not that, check all hoses to evap canister & purge solenoid for possible leak. 1596 is speed control switch malfunction. If vehicle not experiencing any driveability problem, I would disconnect battery for a few seconds to erase codes, then drive it for a while & see if they come back.

OBD II Engine code

P0455 is a EVAP system leak detected code check to make sure your gas cap is tight or if you put gas in it while it was running and can set it . First tighten the gas cap then clear the code and drive and see if the code comes back.
