What does a VTEC oil pressure switch do?
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. When this system fails to operate properly the ECM may set a code.
