What does 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.
What causes the solenoid not to activate VTEC?
If the motor is not maintaining oil pressure or reaching engine temperatures, it can cause the solenoid to fail and not activate VTEC. With the engine cool, pull the dipstick and make sure the oil level is not low. By reading the temperature gauge, when the car is running, we want to make sure it reaches 178 degrees.
What should I do if my solenoid is seeping oil?
Visually inspect the solenoid, oil pan, and oil pressure switch areas for seeping oil. Confirm that VTEC “activates” at 178 degrees. If VTEC does not activate, it may be necessary to replace the solenoid itself.
Why is the solenoid on my Honda Accord leaking oil?
On many Honda vehicles, the VTEC solenoid has been found to be the culprit. More commonly, the gasket could be faulty and all that needs replacing. When this solenoid is bad, the motor’s VTEC will not “activate.”. It is largely dependent on the engine’s oil pressure and engine temperature.
What does VTEC stand for in Honda engine?
As mentioned above, VTEC is an acronym for Honda’s Variable Valve Timing and Lift Electronic Control technology. This is Honda’s variable valve timing system. Effectively, variable valve timing allows engineers to fully take advantage of both the engine’s high and low RPM ranges.
What should I do if oil leaking from my VTEC solenoid?
15815-RAA-A02 VTEC Solenoid Valve Filter (manual); spool valve filter assembly (online parts db). If oil is leaking from the VTEC solenoid, it can only be from these two parts. If you are going to inspect the unit, get the filter since it’ll need to be replaced anyway.
How much does it cost to replace VTEC solenoid in Honda Element?
If it’s hard and brittle, there will probably be oil residue on the bottom of the unit so replace it, the part is about $3. I used a electronic (very small) screwdriver to pick it out of the channel.
How does VTEC work in a Honda engine?
As engine speeds rise, a piston inside the rockers is pressurized with oil, locking all three cams together to increase valve lift. This is where that signature “VTEC kicking in” sound comes from. Now next time you “get into VTEC” while driving your Honda, you’ll know exactly what’s happening inside your engine.
Why is my VTEC oil pressure switch filling up with oil?
Reason for pulling the oil pan and cleaning the oil passages. The new oem vtec oil pressure switch filled up with oil. Had 2 choices, either assume the switch was defective as a brand new component, or too much pressure was building up from restricted oil return passages.
