Hello - I have a 2012 Volvo S60 2.5 turbo and it is currently throwing a trouble code P2402 - Evaporative Emission System Leak Detection Pump Control Circuit High.

According to yourmechanic.com, there are several possible fixes for this issue which are as follows:

• Replace the evaporative pump and fuse.
• Replace the evaporative pump relay.
• Repair the evaporative pump connector pins for corrosion, melted, or loose connections.

I believe I have located the pump on the rear passenger side, but I have two questions:
1.) Where are the Evap pump relay and fuse located? Is there a diagram available?
2.) Should I just replace the pump and fuses? ($85) Or, should I diagnose further? There doesn't seem to be another solution other than corrosion or lose connections.


Any repair advice is welcomed. Thanks in advance.

 

see if this relay map from the 2013 is the same for your car: Cars & Fuses: 2013 Volvo S60 - Fuses

seems the procedure I'd follow is 1) check for a blown fuse 2) check for connectivity through the relay 3) check for voltage at the pump - there's also a purge valve (on my S40 it was up on the front cowling up top on the drivers side by the radiator) but that may throw a separate code. 4) check connections for any melted connectors. Odds are if your pump or relay shorted it would take out the fuse but you need to figure out which...

 

I see that it has a fuse for the EVAP valve, heated oxygen sensor. (position 39 on the diagram) Is this the same as the evap pump?

Also, it doesn't seem to indicate where the relay for the pump is located.
