Q: VTEC not activating

asked by on

My car's VTEC doesnt activate. I heard it could be the solenoid.

The VTEC on your vehicle can be affected by using the incorrect oil viscosity or the VTEC solenoid may be defective. This can be determined by scanning for codes and conducting a diagnostic check to see if the solenoid is bad. I recommend seeking a mechanic, such as one from YourMechanic, to come and test your vehicle for you and determine what repairs are needed.
