- A little off-topic for the farm, but part of being a self-reliant homestead is being self-reliant for all that we have stewardship of. In this case, our 2012 Honda Accord EX--L V6. Check engine light came on, code was a P3400. Diagnosed as a rear oil pressure sensor and how to replace. It's a 10 minute fix and not scary at all! Also applies to any other 2008, 2009, 2010, 2011 or 2012 Honda with the active displacement or their, VCM (Variable Cylinder Management). Fix is the same for the P3497, but it's the front pressure sensor located on the front, passenger-side of the engine.
Honda part number: 2008-2020 Switch Assembly, Oil Pressure - Honda (37240-R70-A04)

Thank you!! This fixed my problem! I was getting the P3400 code on a Honda Pilot 2011. My oil pressure switch on the left side by the oil stick was completely cracked! I went to Advance Auto and got the part for about $38 and the 24mm deep socket for $8. Problem fixed for less than $50!
Hi my honda has the same code P3400 bank 1 on a honda pilot 2011 what should it be thanks ..
I got both codes p3400 and p3497. Ill be going to Advanced Auto too.
Thanks a lot! My crosstour lost power and felt like it was misfiring about 5 miles from my work this morning. My friend had a scanner and the P3400 code came up. 45 dollars and I fixed it in the parking lot after work. I had to get the part from the dealer because I couldn't wait. The light went out and I drove it 40 miles home with no issues!
Awesome! Glad I could help!
Did u have any more trouble out of your Crosstour bc mine just threw a p3400 code
Same thing happened to me! Drove without the alternator until the battery drained out (I'm an idiot) and after fixing the alt I got the check engine light with this code.
Great video. Very helpful, especially where you took time to circle the sensor. Thanks.
A++ video. A simple DIY that the dealer wanted 300$+ for I did it in my driveway in 10 mins.
I encountered the same problem and saw the solution from the video, bought the sensor, and it worked for me, but after only 3 months the problem came back to me again and he asked me to change the sensor P3400
waths the name of the sensor
It's the oil pressure sending unit. Here's my affiliate link to the part. It's the Honda OEM part. amzn.to/3tSSoCs
I bought a spare part with the same description, but after a period of time the same malfunction mark returned and upon computer inspection the code appeared P3400
Did u reset the engine light or did it remove on its own as soon as you replaced it?thank you. Might do it myself tomorrow
In most cases, oil pressure sensor was not the culprit, it is the O ring being hardened over the years and it caused lost oil pressure.
Replaced mine.. typically how long after would the check engine light shut off if that solved it?
Thank you so much. You already know how much money you saved me. Wife and I are going out for a very nice dinner!
Take all the credit!
love the FF/RW sound, reminds me of back to the future... nonono this sucker's electrical, but I need a nuclear reaction to generate the 1.21 jigawatts ~ !
Typically driving so many miles after a fresh oil change will fix the issue to allow the computer to register no fault. Cleaning the sensor gently is another approach. Majority of the time sensors aren’t faulty. Honda’s, especially the Odyssey’s are known for puttering until you service the vehicle. It’s odd, but consistent
U gotta release the push lock on the top back side of that connector, just squeeze top and it unlatches at bottom rim of connector, pull up as u squeeze
I bought my Honda V6 in California (Cali emissions). Is it the same part number? I see BOTH switches have the same part number, but... do they differ between Cali and non-Cali? Thank you.
Lol! I have had this code come up intermittently on my Odyssey. It usually means that its time for an oil change. After I change the oil and make sure that the oil level is good, the light goes out. It doesn't happen everytime but maybe once a year or so. I don't know why but that valve is very sensitive to either oil level, pressure and/or cleanliness of the oil.
Just wanted to update with my issue. I was getting p3497 error then started getting misfires in cylinder 2 and 4 too. I changed all 6 spark plugs took the VTEC or spool valve housing off took a flat head and was moving the spool valve inside housing back and forth with carb cleaner inside soaking it for a few minutes. I put everything back forget her and the pilot if driving so smooth right now. No codes have come back for a couple days now
Awesome! It's a complex system, thanks for the feedback!
Hey, Julian you still code free? Just wondering if that worked...
Cranberry Place Farm yes it worked perfectly. Once it did it i instantly felt the difference. So to anyone getting that code instead of buying anything. Take solenoid housing off and Just move spool valve back and forth with a flat head with a little carb cleaner in it because it just maybe sticking
Mine has misfire on cylinders 1,2 and 3.
Will try this. I think mine has cylinder 3 deactivation mode.
I have P3400 code on my honda odyssey. I deleted the code without replacing this sensor. Drove it for a month ~ 900miles and the code didn’t came back. If it’s the sensor, the code should still come back? Since the code didn’t come back without changing anything, I am wondering what’s the root cause it pop out, thoughts?
I change mine it worked for 40 miles and then it came back I reset it and I'm gonna wait and see how long it lasts before that sensor flips off again.
Did it ever come back on? I'm having the same issue
@@C_P0well75 I change the front solenoid and oil sensor and I have the rear one left to fix my check engine is still on. I left it like that so my Eco mode does not enable and the Van works better like that so it's fixed but not fixed but it is running better without eco mode turning on.
I fixed mine and my 2010 accord is running good now but the Check engine light is still on. It went off for a while when I first drove it and it’s been on ever since for a few days. I had the scanner read it and it was the same code p3400 so what could it still be?
Find a fix yet?
@@Jmp1019 turns out just needed to change my oil, all good.
I have a 2010 Honda Crosstour, the part you named (rear cylinder deactivation sensor) is not coming up at any part store. Is there another name for it ?
I do have the same code P3400
I need you to show me where the other one is please?
Has the light come back on? Has this fixed the issue entirely?
Still good. Has not come back on.
So both sensor part # is the same?
Yes, sir. Super easy job... As long as the engine isn't hot!
How do you reset the 3700 code? Thanks
How did you reset the code to make the check engine light go off?
I used a Bosch obdii code reader that has a reset feature. Most on Amazon or auto parts stores can do it, just make sure in the functions is says, "clear" or "reset" fault codes. I'd give you my model of reader, but frankly, I don't like it very much and am shopping for a new one myself next time something breaks.. :-) Hope that helps!
When you searches for the sensor, what was it called? I have a 2008 odyssey with the same code but says deactivation system bank 1. Is this similar and if so what sensor would I search for on rock auto?
Oil pressure sensor. Here's my affiliate link for the OEM part..amzn.to/335qtEe
What was the Honda pilot doing before you changed the sensor?
Check engine light was on and the "Eco" light quit coming on. No other sign aside from poor gas mileage, which dropped about 20%.
My 2011 Honda odyssey touring check emissions and the cod 3400 so that mean change the same as your car?
Same engine, should be same fix. Mine didn't have any other codes so there may be something else going on. This was super easy and inexpensive, so worth a try...
What’s the part called you replaced?
Oil Pressure Switch (not Sensor)
is it same part number for both bank 1 and bank 2?
They are the same part
Yes.
What's the name of the part again
Question: Did the car was making rattling noise at cold start or while driving?
No noise. Car ran completely normal. If it's rattling, I'd be worried about oil pressure or a lifter maybe...
cool bro, I got the same code on a 2010 accord, what is the part # or link to where you bought it , put an affiliated link so you can earn a small commission too with 40k views people need it
Thanks! Here ya go! amzn.to/2ZvAlp3
I had p3497 code i changed front switch but the code came back on. What should i do next?
If you cleared the code and it came back, that unfortunately wasn't the cause... It could also be the valve timing control solenoid, oil pump, pressure regulator or a PCM issue... Sheesh! At this point I'd continue up the foodchain, or, run it by a mechanic. This fix is by far the most common cause of failure. You could try swapping it with the rear to verify that the code doesn't change to make sure there's not something wrong with the circuit. I believe they're the same part.
Michael Cranston swap what with the rear ? The pressure sensor or the solenoid it self ?
@@julianphillips7391 the front sensor with the rear that I changed. See if the code follows the sensor.
Michael Cranston ok i guess i should of mentioned which i forgot to was that i changed the 2 VTEC solenoid gaskets as preventative maintenance so oil doesn’t leak onto my alternator and after changing the gaskets is when code p3497 came on. I took to a mechanic and he said change pressure sensor which i did.
Michael Cranston i just added a quart of oil because i also read low oil can cause this. If error light comes back I’ll swap sensors thanks
Change the sensor twice, still happens
Hi great video! Do you have the link/part number for the sensor?
Sorry for the delay... Didn't receive a notification... www.rockauto.com/en/catalog/honda,2012,accord,3.5l+v6,1502539,electrical-switch+&+relay,oil+pressure+sender+/+switch,4588. Part 37240R70A02. Hope that helps!
Hi, do you know what to do with the check engine light after the parts are replaced?? light is still on (of course), but how do i fix that?
If you have the scan tool, it should have an option to "reset check engine light", or "clear fault code". Otherwise, the light will usually reset in a period of time without the code.
My car is making a weird sound, almost as if coming from the serpentine belt but the belt looks fine. I have the same p3400 code so I’m hoping this will fix my problem. It seems as if it’s fixing everyone’s p3400 code to do fingers crossed I guess.
Sounds like 2 problems.. That oil pressure sensor is super easy. Step 1! Good luck!
My honda 3.5 is junk...nothing but trouble..
Hondas are junk now, my 2014 Pilot also has the 3400 code😡. No more hondas for me
Man, I feel your pain! Hopefully yours will be as easy of a fix as mine was and you too will be done with the "money light"! I'm cheering for ya! I haven't had any issues since and it's approaching the big 100k... 300k is my goal, if I (or my kids) don't wreck 'em first!
@@cranberryplacefarm1342 thank you. I also hope its an easy fix. Thanks for the vid
eddsramm1 did it fix it? I have a 2014 pilot with same code.
Hondas are not junk lmao
Have you considered acting classes to learn to emote?
I took an acting class in college... It didn't go well...
@@themikecranston you faked it?
