I just found the PET for a 2008 and found the part attached to the carbon canister in the FRUNK. I'll post the diagram when I get back to a computer. Therefore it's not near the TB?

Mine had the same error code and it was the picture above.

If that thing is inside the carbon canister, prepare to curse, scratch your knuckles and have a bad day. I replaced my carbon canister trying to fix my problem and did all of those 3 things. Good luck!

That's the purge valve solenoid. That redirects gas vapors into the intake. It's the one you sometimes hear clicking if you listen carefully with the engine running.
In his case,it sounds like it's the pump by the canister... But I wouldn't swap it out just like that without testing. This is a 50/50 chance you'll get it right. Plus it could be an expensive part swap if it's not faulty : just a quick search reveals 180$ :

To the OP, have you checked this code with your new ODB2 meter? Does it read P2402 like the Indie said?

Hey Chrono... Yes it is the same code.

Here's the PET showing the leak detection pump... Its part #11


How can I test the Pump prior to the $180? What should I buy to do it?

Voltmeter.

Awesome Thanks!!!!!

I just need to mock up a 12 volt power source... I'm going to tear into it tonight. I'll try to capture my steps and we can make a DIY post!

I realize this is from a post about a year ago, but did you ever resolve your issue. My 997TT is having the same one and in the PET that I downloaded it doesn't have the page that you shared, in fact it cuts off on the page before and then starts to a new page.

I am having a "P2402 Pump Motor Final Stage : Tank leak diagnosis module" any suggestions?

I have P2402 on my 997.2 base C2. I purchased a replacement pump but have no idea how to get to it. I can't really get the carbon canister our, or can't figure out how. Is the pump under that?

UPDATE: I figured it out. It's inside the carbon canister box, which is a pain to open and close with those metal clamps. I cleared the code and hopefully the fault will not return.

I had similar codes in my car's records from the prior owner. One time was a failing DTML Pump, the other time was a bad gas cap. Details as follows:

DTML Pump:

- Diagnostics for a CEL
- Codes returned for "Gross EVAP leak"
- Smoke tests found no leak but did find the DTML Pump is failing.
- Remove and replace failing EVAP Leak Detection Pump: $532 ($243 labor/$289 parts)

Gas Cap:

- Diagnostics for a CEL
- Codes returned for P0455 Gross Evap Leak
- Smoke test found that the gas cap is leaking
- Remove and replace gas cap: $137

Does anyone know how to open the carbon canister?

I need to replace the fuel leak detection pump.

I opened the canister and replaced the pump.

This is not easy and you need very strong fingers to get the sheet metal clips back on.

Not to mention getting them off in the first place.

Hey Harry, how did you get that punk cannister to open up? (for future reference.)

Just did it this week. Tried many things and broke two tools.

it comes off with a screwdriver.

have a long magnet if the clip goes down the back
