Heres my issue i got a P1259 code for vtec malfunction...so i replaced the vtec solenoid and the pressure switch on the side if the motor fresh 5w20 synthic oil change and this code keepscoming anything i might be over looking ..any input much thanks stumped

 

Not sure about the code, but i do know a common vtec problem is sometimes a bad thermostat, not totally sure if thats your problem, someone else might have a bit more info on this

 

Is your speedo and odometer working? Is VTEC even engaging? If not, it could be the VSS.

 

The speedo works and ill check out the thermostat

 

Vtec engages sometimes not all the time its qeird

 

Hmm...might try checking the port where the solenoid mounts to the block. Might be clogged. Check the wiring on the Vehicle Speed Sensor anyways. Wouldn't hurt.
