2009 - 2015 Honda Pilot p3400 p3497 Valve Pause System Stuck Off Fixed! Replace Oil Pressure Sensor

Sorry my audio was recording through one channel only on this and a few of my other recent videos. I just fixed the problem for all my future videos, but I can't change the audio on this upload.

Just a quick video showing how I replaced the Oil Pressure Sensor / Switch on the Rear Bank (Bank 1) on a 2011 Honda Pilot. The vehicle had lost power and the check engine light came on. After reading the codes, I found that it had a diagnostic trouble code P3400 for the Cylinder Deactivation System. Other Code Readers might say 'Valve Pause System (VPS) Stuck Off'.
The P3400 code is for the Rear Bank of cylinders (Bank 1) nearest to the firewall. If you have the DTC P3497 it is for the Front Bank of cylinders (Bank 2) nearest to the radiator.
You will see that this is a very quick repair (less than 10 minutes).
This also applies to other Hondas with the active displacement or the VCM (Variable Cylinder Management). The repair would be the same process for the P3497, but it's located in the front bank of cylinders, on the front, passenger-side of the engine.

This can be an intermittent or constant problem and can be caused by several things but is commonly caused by a faulty oil pressure sensor.
It can also be caused by Low Engine Oil Level or Dirty Oil.
In our case, changing the oil pressure sensor (or switch) and O-ring solved the issue. This part is also called the rocker arm oil pressure switch.

This problem is quite common among many other Honda and Acura Models including the Honda Odyssey, Honda Accord, Honda Ridgeline, Acura MDX, Acura TL and more.

Tools Needed:
Large flathead screwdriver to remove the engine cover
24mm Deep socket and ratchet and/or breaker bar

Torque specs I found online: 25Nm or approximately 18 ft. lbs. I recommend checking that in your manual to make sure that's correct.
Do not overtighten this sensor, because you can easily strip the threads.
We were not able to clear the DTC for the P3400 because it was listed as a 'permanent code', but after driving the car for several days, that code went away on it's own.

Thanks for watching!

Dude, thank you so much for this video. My wife had this problem today and we thought we would have to limp the car to a mechanic. I saw this video and did the repair myself. You totally saved us. Cheers.

Wife’s truck went into limp mode tonight. Got the same code on the side of the road, watched the video and changed it in under ten minutes. Up and running. Thank for the video!

[stephaniebowers]

Worked for me, code is off, eco light comes on. Hardest part was finding/retrieving old oil pressure sensor after dropping it. Finally remembered telescoping magnet wand - worked like a charm. Thank you!!

[CaryCrites]

Huge thanks for putting this video out. Saved me a bundle!

[thadankside]

Thank you so much for this simple and east to follow guide on how to resolve those codes. All the Amazon links worked perfectly.

[chudmarcus]

Thanks for the great update, it's a big help. I was just curious what's the app you're using on your phone for all those notifications?

[bipaholic]

Thanks, I am going to change both on my wife’s Pilot today

For those un-informed about the Variable Compression Management (VCM) issues, and the engine failure it can cause, then look into the VCM bypass/delete options that are available. Every car manufacturer that has produced ‘cylinder de-activation’ (eg Ford, GM, MB, etc) vehicles in the past and present all prematurely end up in junkyards!

[moteske]

Why do you have to seat the oring first instead of positioning in place prior to putting the new sensor on it? Seems like an opportunity to drop the o ring.

[duckwacker]

We need a video on how to disable the the vcm

[sammy]

Could this also activate a vtm-4 light?

[garrettstone]

Thanks for the video. Should the check engine light disappear immediately after this fix?

[pitburg]

Would a dirty oil filter throw this code had this issue replaced vcm valve ran fine about a year now having the same issue but sensor appears to be working thought maybe the filter from sitting?

[jb_optnz]

Thank you sir, today, you was my hero

[purpstatus]

And BANK 2? Isn't there an oil pressure sensor there as well? If. So, is it for the rockers? Someone put a 100 ohms jumper on mine for some reason, and I think that the vvt is not properly oiling the rockers on Bank 2

[waynehart]

My local firestone said all parts that may need to be replaced were prior to me bringing my 2010 Accord to them. Said it needs the ECM/PCM to be updated to clear permanent code. Any input?

[gregnixon]

This did not clear the P3400 code for me. I have eliminated the other possible causes, except bad wiring. Oil is clean and full. I cleanned the MAF sesor too. It's time to take it to someone. Changing the oil pressure sensor is a one-minute task. Nothing to it.

[elche]

Great explanation. Thanks so much for sharing

[vivianisa]

All the items are listed on your links including the sensor?

[dontew]

Does this work for a 2015 honda accord exl? can someone respond i cant find a video
