HONDA V-Tec Pressure Switch Video

Describes the operation and testing of the Honda V-Tec hydraulic pressure switch. The ECM monitors the V-Tec pressure switch for a quick response. If the PS does not respond in a specific way and at the right time, it sets a DTC and flags the check engine light. See how it works here with our video training.

@rawrzers Did you do an OIL change? Beware of wrong oil viscosity. If so, replace oil with right value. It is possible to actuate the V-Tec manually and either? listen for engine RPM change (not much). If oil is fine, check for oil pressure. There may be a small filter under the V-Tec Solenoid. Remove the Sol and check that you have pressure. Take any precaution not to cause a fire with the oil. post with more...

@07hondacbr Vtec will never kill the engine,? unless something's shorting when the Vtec solenoid is activated. Look into that path. WHat's shared with the Vtec sol.????

Is it IMportant to have the vtec? pressure switch connected if its obd1? and also does it play a role when vtec is kicking in....

@ADPTraining .... I need to look at this? problem closer, thanks.

@VMATT500C Drivability issues depend on the system. If Honda programmed a? limp-in mode of lower performance, then the ECM may reduce injector pulse, etc. On older systems, the ECM didn't do much in way of reducing performance. But newer vehicles are tougher.

What is? the drivability problem?
