Check Engine light, what is P1494 code?

[V10 ACR]

I recently threw a Check Engine light. Does anyone know what P1494 code is and what I need to do to correct it? Thanks.

1494.... I am at work. But is that not Emissions related?

Is your gas cap on?

That was the first thought. I checked the cap, it was on snug. I loosend the cap slowly and could hear a very loud sucking sound for a few seconds. That makes me think that the cap is sealed fine. Any other ideas? The web shows the following:

P1494 Leak Detection Pump Switch or Mechanical Fault (Chrysler, Jeep)

Is this a gas cap problem or is it something else?

Thanks

I think that's the code for driving like a granny. Drive faster!

I'm at work too so I can't check my manual, but I believe that is the leak detection pump code, which can be anything from the gas cap to something in the fuel system path that gets pressurized during this check.

Check the gas cap. Remove it and re-install it beyond the first few clicks. I usually count about five. Have the code cleared and wait a few weeks. I had the same code a while back and that's all I did. The code hasn't come back in six months.

P1494 - LEAK DETECTION PUMP SWITCH OR MECHANICAL FAULT . There is a service bulletin for certain years pertaining to this problem . Some cars will fill the vacuum line going to the LDP with oil , causing this dtc to trip .

Chris,
Thanks. Is this vaccum line something I can check and clear or do I need to take it into the dealer for service?

You could probobly clear it and it won't show up for a while I don't think it will effect anything. It's an emmission thing. There might be a leak somewhere where the pump is at.

I was just about to say I had the same problem but I guess JiPi beat me to it. I removed my gas cap and replaced it. Then cleared the code (or maybe vice versa). Anyway, it went away and didn't come back. Give it a shot.
