Got a P1495 and P1494 code indication my leak detection pump may have failed. Does anyone know where this pump is located on the vehicle?

Thanks,

Hi, If you look under the drivers side just under the steering gear if I remember correctly you should see a cast aluminum plate, Its under there. However, I'd also suggest doing a vacuum test on the entire system because leaks elsewhere can sometimes generate the same codes.

 

Thanks for the reply. That was very kind of you to try and help. I will look at that issue today when I get home. I had some suggest it was by the gas tank and some suggest it was up front so I was trying to narrow my search. I was getting a battery lite previously which I traced back to the PCM. After replacing the PCM with a rebuilt one the battery lite issue went away but the LDP issue arose. I still have the old PCM so I may just put it back in and see if the LDP code goes away. Anyway, I'll keep you posted on what I find and thanks again for your help.

I cleaned up the contacts on the original PCM and put in back in the van. All problems went away. No codes, alternator charging, working like a champ. This has been a weird one but at least it has had a happy ending. Thanks to all for helping with your input.
