I’m having v-tec problems with my h22 accord and I need to know the following.

1 I just pulled a code and I’m getting a code 12 which is the Egr valve could this be a possible reason.

2 My tach does not work, I’m not sure if it’s the tach itself or the blue wire on the dizy is not getting power. Would this affect my vtec? I need to know specifically if the tach is getting power but simply not working would it matter, or does the tach actually need to show the RPM in order to work?

3 The Egr valve is on the manifold correct right behind the oil cap.

 

its probably the code. check it out on a code chart. i believe theres a link to a code chart in my sig. itys not the wires from your tach. did you install the tach yourself?

 

When my swap was completed the tach for some reason decided it did not want to work anymore. I know what the code it's a Egr valve code. I wasn’t sure if this had anything to do with it or not.

 

no the egr should not cause the vtec to not work. however either get a stand alone so you can get rid of the egr system or get it fixed
