There are a few ways that you can bypass the VTEC oil pressure switch. One way is to purchase a replacement VTEC solenoid and install it in place of the old one. Another way is to disconnect the wire going to the VTEC oil pressure switch and connect it to ground.
This will trick the ECU into thinking that there is always oil pressure present, and it will engage VTEC all of the time.
- Disconnect the negative battery cable
- Drain the engine oil
- Remove the oil filter and pressure relief valve spring using a pair of pliers
- Unscrew and remove the vtec solenoid cover bolts with a 10mm socket wrench or ratchet, then pull off the cover to access the vtec solenoid wiring harness connector plug
- Cut and strip away about 1/2-inch of insulation from each of the 4 wires on the vtec solenoid connector plug using wire cutters or a utility knife, then twist each wire around a small screwdriver until it’s tight against itself so it can’t move anymore
- Doing this will prevent any shorts from happening when you bypass the vtec oil pressure switch later on
- Use a multimeter set to its ohms function to test for continuity between each of the 4 wires on the vtec solenoid connector plug and ground (any bare metal part of the car body)
- If there is continuity, that means that particular wire is good and you can proceed to step 7
- If there is no continuity, then that means that particular wire is bad and you’ll need to replace it before continuing further
- You can also test for continuity by touchi7ng one probe of your multimeter to each wire on the connector plug while touching the other probe of your multimeter to ground (again, any bare metal part of the car body)
- If your multimeter beeps or lights up, then there’s continuity and that particular wire is good
- Replace any bad wires before proceeding to step 7
- 7) Take some electrical tape and wrap it tightly around all 4 wires where you stripped away insulation in step 5 , overlapping each layer by about half an inch
- This will insulate them from each other so they don’t short out when bypassingthe vtec oil pressure switch later on
- Make sure not to tape over any ofthe exposed metal connectors at either end ofthe wires!
How Do You Bypass an Oil Pressure Switch?
Assuming you would like tips on how to bypass an oil pressure switch:
The most common reason for wanting to bypass an oil pressure switch is because it is preventing the engine from starting. There are a few ways that you can bypass the switch, but it is important to understand that this is not a permanent solution and should only be done if absolutely necessary.
One way to bypass the oil pressure switch is to simply disconnect it. This can be done by locate the wires going to the switch and cutting them. This will allow the engine to start without any oil pressure, so make sure you keep a close eye on your oil level and do not run the engine for too long without adding more oil.
Another way to bypass the switch is by jumpering it. This means connecting two wires together so that electricity can flow through and trick the system into thinking there is enough oil pressure. To do this, you will need to locate the two terminals on the switch that need to be connected.
Once you have found them, use wire strippers to remove some of the insulation so that you can connect the wires directly together with a piece of electrical tape or wire nuts.
Once again, neither of these solutions are permanent and should only be used as a last resort when trying to start your engine. Be sure to check your oil level often and add more when necessary while running your engine with a bypassed oil pressure switch.
What Does a Vtec Oil Pressure Switch Do?
In order to understand what a VTEC oil pressure switch does, it is first necessary to understand what VTEC is. VTEC stands for Variable Valve Timing and Lift Electronic Control. It is a system found in Honda engines that allows the engine to operate with more than one camshaft profile.
This system improves fuel economy and emissions while also providing increased power when needed. The oil pressure switch is a part of the VTEC system that controls the oil pressure in order to activate the different camshaft profiles.
When the engine is operating at low speeds, the oil pressure switch activates the hydraulic valve lifters, which allows for lower lift and shorter duration intake valves.
This reduces fuel consumption and emission output. When the engine speed increases, the oil pressure switch deactivates the hydraulic valve lifters and allows for higher lift and longer duration intake valves. This provides increased power output from the engine.
How Do You Test a Vtec Oil Pressure Switch?
In order to test a VTEC oil pressure switch, you will need the following tools:
-A multimeter
-A 12 volt test light
-An assistant
First, locate the VTEC oil pressure switch. It is usually located near the oil filter on the engine block.
Once you have found it, disconnect the electrical connector from the switch. Next, using your multimeter, set it to the ohms setting and touch the probes to the two terminals on the switch. If there is continuity between these two terminals, then the switch is good and does not need to be replaced.
However, if there is no continuity between these two terminals, then this indicates that the switch is bad and needs to be replaced. To test this further, you can also use a 12 volt test light. Simply connect one end of the test light to ground and touch the other end of it to each terminal on the switch in turn.
If continuity exists between those two terminals, then they should both light up brightly when touched with one another.
Can You Disable Vtec?
VTEC, or variable valve timing and lift electronic control, is a system found in many Honda engines that allows for more power and efficiency. The system works by changing the timing and lift of the valves based on engine speed; at lower speeds, the valves open less to save fuel, while at higher speeds they open more to allow more air and fuel into the cylinders. VTEC can be disabled through a process called “limp home mode.”
This is typically done when there is an issue with the VTEC system itself, or with one of the sensors that tells the system when to engage. In limp home mode, the engine will run without VTEC, typically at lower power and with reduced fuel economy.

Where is the Vtec Oil Pressure Switch Located
The vtec oil pressure switch is located on the back of the engine, near the firewall. It is a small, black, rectangular switch with two wires going to it.
Vtec Oil Pressure Switch Circuit High Voltage
If you have a high voltage reading on your VTEC oil pressure switch circuit, there are a few things that could be causing the problem. First, make sure that all of your connections are clean and secure. If they’re not, that could be causing an electrical issue.
Second, check your oil level and make sure it’s full. If it’s low, that could be the reason for the high voltage reading. Finally, if none of those things seem to be the problem, it’s possible that the switch itself is faulty and needs to be replaced.
Vtec Oil Pressure Switch Honda Crv
If you own a Honda CRV, then you know that the Vtec oil pressure switch is one of the most important parts of your engine. This tiny little switch controls the oil pressure in your engine, and if it fails, your engine will not run properly. Here’s what you need to know about this vital piece of equipment.
The Vtec oil pressure switch is located on the side of the engine, near the oil filter. It’s a small black switch with two wires coming out of it. When you start your engine, the oil pressure in the system rises and closes the switch, allowing oil to flow through to the Vtec system.
If there’s not enough pressure, or if the switch is faulty, then your Vtec system won’t engage and your engine will run rough.
Replacing the Vtec oil pressure switch is a pretty simple job that anyone can do at home with just a few tools. You’ll need a newswitch (you can get these from any Honda dealer), some pliers, and a ratchet set.
First, removethe old switch by unscrewing it from its mounting bracket with a ratchet. Then disconnectthe two wires going to theswitch by squeezingthe pliers together and pulling them apart.
Now take your newswitch and screw it into place in the bracket using a ratchet (it should go in easily by hand).
Reconnectthe two wires to thenewswitch – they only fit one way so don’t force them – and give it acoupleof cranks to make sure everythingis working properly before putting everythingback together again.
And that’s all there is to replacingyour Vtec oilpressureswitch!
How to Straight Wire Vtec
If you own a Honda vehicle equipped with Vtec, you may be wondering how to straight wire the system. While there are many ways to do this, we’ll walk you through the easiest and most effective method.
First, locate the two vtec wires on your engine block.
These will typically be labelled “VTEC Solenoid” and “VTEC Pressure Switch”. Next, use a pair of pliers to twist each wire clockwise until it is tight.
Now it’s time to connect the wires to their respective destinations.
The “VTEC Solenoid” wire should be connected to the positive (+) terminal of your battery, while the “VTEC Pressure Switch” wire should be connected to a 12v source such as an ignition switch or keyed power source.
Once everything is hooked up, start your engine and enjoy the increased performance that VTEC provides!
Conclusion
Vtec oil pressure switches can be bypassed by tapping into the wire that goes to the switch and grounding it. This will fool the computer into thinking there is enough oil pressure, even if there isn’t.
