  • 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.

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.

What is a rocker arm oil pressure switch?
