What does the VTEC system in a Honda engine do?
Image Gallery: Engines The VTEC system in Honda engines allows the engine to have multiple camshafts. See more car engine pictures . If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about the camshaft that controls the valves.
How tall is the Honda Civic 4D 1.5 VTEC E?

How does the camshaft in a Honda engine work?
The camshaft uses rotating lobes that push against the valves to open and close them. Check out How Camshafts Work for more information. It turns out that there is significant relationship between the way the lobes are ground on the camshaft and the way the engine performs in different rpm (rotations per minute) ranges.
Where is the thermostat located on a Honda Civic?
Once you have the coolant drained from your engine, you can begin our how to guide on how to replace a Honda Civic thermostat. The thermostat housing on your Honda Civic is located behind the distributor and mounted just above the starter.

What does the thermo switch on a Honda radiator do?
If the fan switch relay is giving off the appropriate readings and is in working condition, move on to the next step. The thermo switch (also called the cooling fan switch) sends a signal to the cooling fan, so the fan turns on if the coolant gets too hot.
Where is the ECT sensor on a Honda Accord?
Follow these steps to test it: Locate the ECT sensor, which is just below the distributor. Unplug the sensor. Bridge the gap in the sensor connector with jumper wires. See Contact Test in Step 1. If the radiator fan does not come on, you will need to replace it. Figure 4. Location of ECT sensor for a ’98 Accord.
Where is the solenoid on a Honda Accord?
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. Figure 3. Solenoid location.
How often do the valves open and close in a Honda engine?
That would work great for the engine as long as it ran at this very slow speed. When you increase the rpm, however, this configuration for the camshaft does not work well. If the engine is running at 4,000 rpm, the valves are opening and closing 2,000 times every minute, or thirty to fourty times every second.
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.
