How do I bypass the VTEC oil pressure switch?
The VTEC Oil Pressure Switch Wiring can be easily bypassed as follows:
- Locate the VTEC Oil Pressure Switch Plug on your engine harness (this wire comes from OBD1 ECU Pin D6).
- Simply TAP this wire into the VTEC Solenoid Valve Wire (the VTEC solenoid wire comes from OBD1 ECU Pin A4).
What does the VTEC oil pressure switch do?
VTEC stands for Variable Valve Timing with Electronic Control. The variable valve timing oil pressure switch is a normally open switch located at the VVT solenoid. When the VTEC oil pressure switch closes, the voltage should drop to zero. This is how the PCM knows if oil pressure was applied to the VTEC system.
How do you test a VTEC pressure switch?
To test for continuity on the vtec switch, set the meter appropriately (like picture) and touch one lead to each of the two pins on the vtec switch itself. To test for continuity of the vtec circuit in the ECU, you woud touch one lead to each of the pins in the unplugged wiring harness.
How do you know if your VTEC solenoid is bad?
Here are a few symptoms of a worn out or broken VVT solenoid.
- Check Engine Light comes on. Since today’s modern cars are controlled by an Engine Control Unit (ECU), virtually all individual components are monitored by the ECU.
- Engine oil is dirty.
- Rough engine idle.
- Decrease in fuel economy.
How do I know if my VTEC is working?
SO MAKE SURE YOUR CAR IS WARMED UP AND YOU HAVE A SUFFICENT OIL LEVEL. When the wires touch you should definately feel a differance, well, that is if your vtec is working.
How do you replace a VTEC oil pressure switch?
Remove the electrical connector to the VTEC oil pressure switch (aka valve timing oil pressure switch) and the 2nd connector to the spool valve assembly. 4. Remove the three 10mm bolts mounting the spool valve assembly to the cylinder head.
How to replace a VTEC spool valve assembly filter?
To create space remove the single 10mm bolt mounting the power steering high pressure line to the valve cover. 3. Remove the electrical connector to the VTEC oil pressure switch (aka valve timing oil pressure switch) and the 2nd connector to the spool valve assembly. 4.
Why is my VTEC switch not working properly?
Make sure you check your oil level ASAP as some VTEC DTCs are set due to a loss of oil pressure due to low oil levels. The misfire DTC’s can be disregarded until the VTEC system is operating correctly. Well, I took it back to the dealer where I bought it and they told me it was the oil pressure switch.
Do you cut the solenoid wire on a VTEC pressure switch?
Do not cut the VTEC solenoid wire, simply connect the Vtec pressure switch wire to it. That’s it, your ECU will now be fooled into thinking that it has a VTEC pressure switch and VTEC will now function. Enjoy!
