 Subject: P1494 error? LDP Help please
IP: Logged
Message:
I have the engine code error:
P1494 - Leak Detection Pump (LDP) pressure switch problem - electrical or the pump itself
I have no idea what that is. I read some posts on it saying it was Underneath the battery on the drivers side front. I don't know what it looks like. I did take the engine all apart once because I was going to swap engines, but then I put it back together since I sold the engine. Maybe I forgot to plug a wire back in. Or the engine overheated once and maybe an electrical circuit got wet.
Anybody know how to fix this?

Check your connections and vac lines on canister
drivers side down by frame
could be gas cap
the gas tank vent system is pressurized threw the
canistor any leaky line or a bad gas cap will
trip the code

Thanks for the help. I'm only able to check the site on the weekends since I work out of town (construction). Sorry for the late response.
I'm thinking it's a vac line, gas cap seems fine and I had the problem after I put the engine back together. I probably missed a connection somewhere or a hose is loose. I'll go out today and check all the connections.

I had the same code about a year or so back. And the gas cap looked fine to me also but I said ahh hell i'll spend 10 bucks and get a locking one anyways. And guess what? It fixed the code.
