VTEC (Variable Valve Timing & Lift Electronic Control) is a system developed by Honda to improve the volumetric efficiency of a four-stroke internal combustion engine, resulting in higher performance at high RPM, and lower fuel consumption at low RPM. ... It was invented by Honda engineer Ikuo Kajitani.

What are the symptoms of a bad VTEC solenoid?
What are the symptoms of a bad VTEC solenoid? The most likely scenario with a VTEC solenoid failure is when you get a check engine light, and the car will likely go into limp mode, often leaving you fearing the worst.
Can you drive with a bad VTEC solenoid?
In some cases, the motor may run (not very well) with a broken or damaged variable valve timing solenoid, however it will likely not run for long due to the critical role the VVT solenoid plays in the timing of the motor.
How do I fix my VTEC system malfunction?
The most common cause for Error Code P1259 or VTEC system malfunction is low oil pressure. Thus, make sure you check your oil if it's due for service. Change oil and filter if necessary. Clear the codes and then give it a try.
How do I know if my VTEC is working?
The meter should read very very low voltage until vtec hits. If vtec activates then the voltage should read around 12. if not then your ecu may not be functioning properly.
What happens if you don't replace a oil control valve?
But with a faulty oil control valve or VVT solenoid, excess engine oil may be introduced into the VVT system which can result in rough idling, stalling, or just poor engine running in general.
What happens if you dont use VTEC?
If you disable it, then the engine would be stuck in either high or low RPM mode, and it would function at less than best capacity whenever the RPM was not in the right range.
What does the VTEC 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.
Is it bad to hit VTEC?
In a straight line, 'hitting VTEC' often results in noticeably more power and a satisfying sound as the cam profiles shift. ... The clip below answers that age-old question and to our surprise, yes, you can hit VTEC in reverse, not that doing so serves any real purpose.
At what RPM does i VTEC kick in?
At low RPM, the VTEC-E system effectively forces the engine to operate as a 12-valve engine - one of the intake valves does not open fully, thus decreasing fuel consumption. At 2200RPM, the VTEC-E system engages the 2nd intake valve, effectively resuming operation as a normal 16-valve engine.
