Honda V6 Engine J35A7, with VCM (Variable Cylinder Management)
shown in the 2010 Odyssey Ex-L

## Reason

* Check engine light P3400
* Valve Pause System (VPS) stuck in off position - bank 1

## Supplies

## Tools

1. Ratchet socket/box wrench
2. 24 mm deep socket
3. Torque wrench (set at 13 ft pounds)
4. Pick

## Preparation

1. Pop the hood
2. Remove the engine cover

## Oil Pressure Switch Removal

1. Find the bank 1 (in the back, to the firewall) oil pressure switch
2. Remove connector to the oil pressure switch
3. Use a 24mm deep socket to remove switch
4. Use a pick to remove the existing gasket, possibly stuck on the engine
5. Clean the surface

## Oil Pressure Switch Replacement

1. Lubricate the new o-ring with engine oil.
2. Put the new o-ring back on the engine contact.
3. Thread the oil pressure switch on, and make sure the o-ring is in place.
4. Torque the switch to 13 ft lb or snug.

## Check

1. Start engine and check leaks
2. Clear code and test drive

## Additional comments

Some service manuals (on older models) suggest the use of liquid gasket on the thread.
However, I don't see anything on the factory switch thread and skip this step.

It is working fine and so far no leak on the Odyssey.

Thank you Professor. How would you determine if it was the bank 1 or bank 2 oil pressure switch? Thanks again.

[cubmancan]

Thank you, Sir! Great video! Could I ask you what OBD reader you are using here? It seems to give more specific information than some others!

[miguels]

Nice video thanks how I clear the engine light?

[truslo]

Do the same steps apply for the J35Z2 - VCM engine? (2010 Accord V6). Same code and my dealership wanted to change the entire rear spool valve

[ekaterinabaldina]

Hi! What instrument did you use to loosen the oil switch?? Did you use torque wrench to tighten it?? Thank you!

[phroskies]

Same code for a 2011 V6 accord. Is it the same thing?

[JohnEscobar-jx]

Hey man! Can this be done with a 2009 accord ? I get the p3400.

[dontew]

Can someone please tell me is the switch in the back of the engine or do I have to remove the passenger tire.

2015 hond accord v6

I have a 2011 Honda Pilot, I need to replace this part. How do I know what the part number is ?

[taurotech]

tanks so much but have a ?you put new ring end what can oil mix with ring tnaks again

[qvmb]

I’m getting this code along with a misfire on Cylinder 4. Do you think replacing this will fix it? Or is it something else.

[Username-wx]

Where can we get the parts number ? And o ring gasket

[jacksonparkhurst]

Was it driving bad when the engine light came on? I'm thinking the reason my pilot is driving bad is this but I'm not sure.

[SuperJayjay]

I couldn't remove the connector in tight space.
