Where is the oil pressure switch located on a 2008 Honda Odyssey LX with a 3.5 Vtec engine? Just to let you know my van doesn't have it above or behind the oil dipstick.

The oil pressure sensor is located above the oil filter, it is a single wire connector with a rubber boot over it, not the 2 wire or 1 wire plastic connectors. Should be able to access it from the passenger wheel well.

If it's not on the cylinder head,it will be on the oil pump housing.

    Thank you, I will check that and let you know.

    Okay, I checked over by the oil filter, pulled what I thought was the oil pressure switch out, but the part I got PS702 from Autozone is too big for my car. So.. Im back to square one. Thank you to everyone who has helped so far its greatly appreciated. My problem is that my oil pressure light comes on intermittently, blinks while driving, stays solid when in park. If I turn car off/on it goes off until the next time I turn car on. I check my oil daily and its full, just did oil change in last 3 weeks so oil is clean. Pepboys, Oreillys & Autozone all offer same part for my car. There wasn't a rubber boot over what I thought was the oil pressure switch in my car and the plug didn't fit the part I got. Could there be another type of oil pressure sensor/connection I don't know about?

SOURCE: location of oil dipstick

The oil dipstick is located at the back of the engine.  If you look at the engine from a top view it is located at about 11 o'clock.  It's black.

SOURCE: Can't find the ''cabin air filter'' on my 1996 Honda Odyssey

A 1996 Honda Odyssey is not equipped with a cabin air filter. If I was looking for a restriction in the cabin air, the first place I would look is on the inlet side of the A/C condensor. ALL cabin air travels through the A/C condensor ALL of the time. (The heater core only sees air when the temp door is not directing the air around it and always after it has been through the condensor first.) I have seen gunk as hard as concrete clogging the condensor just from layers of dirt that collects on the wet coils then dries.

Testimonial: "Dear dttech, Thanks for the tip on the possible blockage on the inlet side of the AC condensor. Makes alot of sense and I will check there tonight. Is is difficult to access that area and how can I clean it once I get to it. Do I have to completely remove the condensor ? Thanks again for your help."

What does a po1259 code for a 2001 honda accord 3.0 litre, v-tec b-1 sys. failure mean

Here is the explanation from engine-codes.com

P1259 Honda Description
The VTEC system activates the VTEC solenoid valve by command from the powertrain control module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that is installed in the valve system to switch valve timing between Low and High. The PCM monitors oil pressure conditions in the hydraulic circuit of the VTEC mechanism according to the VTEC oil pressure switch downstream of the VTEC solenoid valve. If there is a disparity between oil pressure condition in the hydraulic circuit that is determined by the PCM command, and the oil pressure condition that is determined by the status of the VTEC oil pressure switch, the system is considered faulty and a DTC is stored.

I have a 2004 Honda Civic VTI, the engine checklight came on and I went to 3 different computer diagnostic centres and the scan showed VTEC system failure. I changed the VTEC solenoid, change vtec pre

What is wrong is that you changed a part

You failed to follow any trouble charts because
you have none

The sensor was most likely okey & just doing it's
job of reporting a fault

You could have a mechanical problem such as a timing
belt issue or worn VVT Actuators on the end of the cames

You have to diagnose code related issues & then find out
why a sensor reported as it did

Even if you scoped the sensor you would most likely
assume it was bad,not so,have to keep thinking why the
data was bad

You need professional tools & look at several pieces of data
overlayed on a big sceen at one time

Repair shop or dealer for that issue

How do I replace oil pan gasket on a 2003 Honda CR-V

My honda accord 2003 V6 hiccups when I step on the gas, and the right signals do not work. The code P1259 came up and I was wondering excatly what does that mean?

This is an error code related to VTEC related Honda engines. I am sending you a little reading on that error code.. Best of Luck..


The Check Engine Light (CEL) is on. Trouble code P1259. Tests/Procedures: 1. Locate the Variable Timing/Lift Control (VTEC) pressure switch, on the back of the cylinder block, by the oil filter.

2. The VTEC oil switch is normally closed and grounds the reference voltage from the Engine Control Module (ECM) on the Blue/Black (BLU/BLK) wire.

3. At approximately 4000 RPM, and when driving the vehicle, the VTEC system should turn on. To turn the system on, the ECM energizes the VTEC Solenoid valve and it allows oil pressure into the intake valve rocker arms, the oil pressure opens the VTEC oil pressure switch so the ECM can verify that VTEC did turn on correctly.

4. The code will set below 4000 RPM if the reference voltage is not grounded. The code will set above 4000 RPM if the VTEC oil switch does not open.

5. If the code sets at 4000 RPM or higher, the problem can be a low oil level or pressure, or a malfunction in the VTEC assembly. Potential Causes: Low Engine Oil
Plugged Oil Passage
Insufficient Oil Pressure
Plugged Oil Screen
Insufficient Oil Volume
Malfunctioning VTEC Oil Pressure Switch
Defective VTEC Solenoid
Tech Tips: When the P1259 code sets at 4,000 RPM or higher, always verify that the engine oil level is full. Also, if there is an oil pressure or volume problem, always verify that the oil pan is not pushed up and is too close to the oil pickup tube, causing an oil volume problem. Be very careful when supporting the engine with the oil pan.

TELL ME WHAT CHECK ENGINE LIGHT CODE YOU ARE GETTING.CODE SCAN AND TELL ME WHAT CODE YOU ARE GETTING.MOST VTECH ENGINE HAS PROBLEM WITH VTEC SOLENOID OR VTEC OIL PRESSURE SWITCH.MOST TIME CHECK THE OIL PRESSURE BY REMOVING VTEC OIL PRESSURE SWITCH FROM THE LOCK UP SOLENOID AND CONNECT AN ADAPTER BETWEEN THE SWITCH AND THE SOLENOID. BUT I CANT SAY ITS YOUR VTEC SYSTEM UNTIL YOU CODE SCAN CAR.OIL PRESSURE SHOULD BE 50 PSI @ 3000 RPM OR 85 PSI @3000 RPM.

I have code p1259

code 1259 is the actual v-tech code and oil pressure codes go from po520-po523. Many people do not have any idea what v-tech actually means. It's an actual oil solenoid valve that opens up above 4000 rpms and adds extra oiling to the cylinder head. To set this code po1259 you would have had your car above 4000 rpms for more than 3 seconds i believe and have this valve not work. Chances are that the valve it's self in the head is bad and setting this code. I have had it happen on a few other Honda's

I have a Honda 2004 CRV - the repair ( OBD II) code is P2647 - what does that mean?

P2647 VTEC Oil Pressure Switch Circuit High Voltage - With Automatic Transmission Basicallly the sensor has gone bad or an oil passage has become blocked.

**. Locate the Variable Timing Electronic Control (VTEC) pressure switch on the end of the cylinder head. Honda has had problems with the VTEC oil pressure switch, there is an updated part number for the vehicle (37250-PNE-G01). On this vehicle the VTEC oil pressure switch can fail at any RPM.
2. The VTEC oil switch is normally closed, and grounds the reference voltage from the Engine Control Module (ECM) on the Blue/Black (BLU/BLK) wire. If the code sets at idle - 2500 RPM - and the Brown/Yellow wire has a good ground, then suspect a faulty VTEC oil pressure switch.
3. At approximately 2500-4000 RPM and when driving the vehicle, the VTEC system should turn on. To turn on the system, the ECM energizes the VTEC Solenoid valve and it allows oil pressure into the intake valve rocker arms, the oil pressure opens the VTEC oil pressure switch so the Engine Control Module (ECM) can verify that the VTEC did turn on correctly.
4. The code will set at idle to 2500 RPM if the reference voltage is not grounded. The code will set above 2500-4000 RPM if the VTEC oil switch does not open.
5. If the code sets at 2500-4000 RPM or higher, the problem can be a low oil level or pressure, or a malfunction in the VTEC assembly.
Potential Causes: Low Engine Oil
Plugged Oil Passage
Insufficient Oil Pressure
Plugged Oil Screen
Insufficient Oil Volume
Malfunctioning VTEC Oil Pressure Switch
Defective VTEC Solenoid
