It's not a Leak Detection Pump (LDP). Its a EVAP System Integrity Monitor (ESIM). They are not the same thing. Older Dodge Caravans used a LDP but the newer ones use an ESIM. There is a lot of confusion in the auto parts world about exactly what this component is called. An LDP uses engine vacuum to cycle a diaphragm to pump up the system to test it for leaks. A system that has an ESIM uses the normal pressure variations created in the gas tank when the fuel vaporizes and condenses to test the system so no pump is required.

My car (2015 Jeep Renegade 2.4l 4-cylinder) has had tripped P0440, P0452, and P0456. I took it into my local mechanic for diagnosis. After the problem being diagnosed and having the engine computer flashed by Mopar, I have narrowed it down to being this specific part. I ordered parts and after watching this video, I feel more confident in being able to perform the job myself because labor is expensive 😅 I appreciate the how-to in the previous video!

From my understanding, if it rattles when you shake it, it is toast. It shouldn't rattle like that.

For some reason Mazda decided to make this replacement job almost impossible.

Well, Iowa has NO such emissions tests; and as we are now deep RED, and getting REDDER, there never will be, thankfully. If there were, 2/3 of all farm vehicles would fail miserably.

Electrical testing of components should be included in repair videos to prove their at fault in my opinion otherwise just a parts changer.

I was unable to fill gas tank without the nozzle clicking off continuously. Changing this was an option. The video i watched said if you shake the part and it rattled, it was no good. Mine did that and the new replacement did not rattle. I drove to gas station and was able to fill up tank with no issues. 2014 Ram 1500.

@MrMctheking

I have purchased the exact item from the link. It arrived and looks and functions differently than the one in your video. The weights don't move and there are 2 instead of one. The new one looks exactly like my current one with the 2 weights and the current weights don't move either. Amazon tells me I bought this exact one 5 years ago and that is the one I am replacing.....Even in the item images there are two weights not one like you show......so whats incorrect here? The part or that it should have a single weight or that they should move? Thanks---In NY and they really care

Rural counties in Oregon don't require Emissions tests that I'm aware of. Yet.

Nice job with a bit of humor and wit. You may have saved many from expensive tests and repairs that were not needed Thank you!

@sourdruid1

Ended up researching my p0440/p0456 code and this did the trick. I initially got got the purge valve code and changed that and still had the code. Checked vacuum hoses and charcoal canister and after more research saw nothing wrong so last cheap option before a smoke test or canister change would be the detection pump.

Hello, thank you ver much for your video, congrats for your Good work! I have a question about the eléctrical switch, is there a way to check it? I provided 5v to the switch simulating the pcm and there is no any sound inside, I should hear the mechanical switch movement sound, right?

@jnstrcklnd

So i have a p0456 code and i replaced this today. The old one rattles like your did and the brand new one i installed doesnt rattle.

@kevinlange7319

With the Engine off, and a Smoke test running I get smoke out of the ESIM breather vent behind the Gas Filler. (2015 Jeep JKU). Is the Valve for the vent supposed to be closed with engine off or open?

@dustenevans6047

I have 2018 charger sxt plus replaced purge valve canister, fuel tank pressure sensor still have code p0452 had water in my Evaporative System Integrity Module and the charcoal canister bought new esim and baking the charcoal canister at 225 degrees over night to dry, I’m curious how did I get water there and why? Also will this help?
