Can a misfire cause oil burning?
Plus, a lot of people don’t know that when a misfire occurs in the intake, some of the flame is sent through the ventilation tube into the valve cover and beginning to burn the oil and oil guide seals on the valve train. This can lead to pre varnished oil and oil consumption.
Can bad coil packs cause oil consumption?
It’s possible in an indirect way but oil leak would not be the primary problem. A bad ignition coil causes misfires, leaving unburned fuel in the cylinder. Now, the fuel goes in two directions from there: the exhaust port and into the crank case.
Can bad spark plugs cause more oil consumption?
Consequently, worn or cracked intake valve stem seals can; leak oil through the, valve guides. Also, the spark plugs might show some oil ash accumulation; on the side of the electrode, facing the intake valves. On the other hand, most oil consumption is; through the pistons and piston rings.
Can a P3400 code be a false positive?
Sometimes the P3400 can be a “false positive” in the sense that it is indicating the sensor is bad (or oil pressure is actually low) when in actuality, the computer is not managing the VCM properly. Also what ends up happening is excessive oil consumption at lower speeds (~40 MPH).
What causes the P3400 code to set on an odyssey?
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…….

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.
Why are the DTC P3400 and p3497 set?
DTC P3400 (rocker arm oil pressure switch B) and/or P3497 (rocker arm oil pressure switch C) may also be stored. POSSIBLE CAUSE During a cold start, the engine oil pump outputs high oil pressure. DTCs P3400 and P3497 are set because of the high oil pressure measured at the VCM spool valve.
What does P3400 stand for on Honda Odyssey?
P3400 relates to bank 1, which is the rear cylinder head VCM solenoid. As a test, I unplugged the oil pressure sensor, and the Odyssey now ran in 6 cylinder mode ALL the time.
How much is the oil pressure switch on a Honda P3400?
This is a little basic video i made on p3400. There is a troubleshooting guide in the honda service manual, but an oem rocker arm oil pressure switch and oring is only about $27. Takes a couple minutes and is worth a try.
