Low oil level can cause this P3400 code to set. A loose gas cap and/or dirty cabin air filter WILL NOT cause this P3400 code to set. The most obvious symptom was that the Odyssey was operating in 3 cylinder mode nearly ALL the time. There was a significant drop in power. Heres why…….
What to do if your car has a P3400 code?
The most common cause of this problem is low oil level or pressure. Start by checking your oil levels and put more oil in if necessary. If that does not solve the issue, then you should have a manual oil pressure test done. Afterward, you can try driving the vehicle and see if the code reappears.

Is there a P3400 code for the VPs?
VPS seems to be a “vapor pressure sensor” and is most likely mounted on the fuel tank. You may in fact have a problem with your VPS, but that would not set a P3400 code. It would set something in the P04xx range, as it deals with the EVAP system.
