P0035 turbo bypass valve issue??

[Fk_1.5t]

just came back from a drive with my hondata plugged in. I tend to randomly check the trouble codes and noticed a P0035 code. Should I not be driving the car till it’s fixed or?? No check engine light came on or anything weird just that code. I see the CTR has been experiencing it lately. However I have a Civic ext 1.5t manual trans with full bolt ons and a custom tune. Just wondering what the issue can be? Thanks in advanced!

Try to limit driving when there are engine codes. According to some forums, it can be an issue with the ECU. Bring it to the dealer as it seems to be a common issue as of late.

I hear the wires under the harness connected to the bypass valve under the hood is the issue for the P0035 and P0034 high/low voltage codes. I hear Honda makes the wires out of soy which are weak and get destroyed by the natural resonance from the car. Either way I'm taking my car to the dealer Monday morning and I'll let you know what they did for the fix. I have 72,000 miles on my ex t Civic and the lights never came on up until I hit 71,000 miles mark. When did you lights come on?

Seconded on that

I got my car fixed by the Honda dealer for the P0034 and P0035 codes. It was the wires that were broken but I got the wires from Honda for 21$! Labor is 140$ for it but it seems like you can do it yourself with basic garage tools. I'll take a picture of where the wires are located tomorrow.

When I had the codes it ran 2 bars of boost and Now that the codes are gone it can fill the entire gauge again.

2 bars of boost. All the lights came on as well. I hope we have the same problem because the fix wasn't that much at all. Good luck to you and I hope you get you car fixed.

Also waiting on the reply, dealership told me it was happening because I had too many things using power (2 radar detectors and a dashcam..)

Can’t use boost when the error happens and I get a Christmas light version of error codes on the dash display. A picture of the location and the part would be awesome

I found the following thread and noticed that the wire was pretty damaged and ended up snapping when even barely touching it.

Will replace that wire and update here if that perma-fixes this.
