Hello all,
For a 2014 Chevrolet Cruze 1.4l Turbo.
Recently we took it to a shop for the code P2261, turbocharger bypass valve. The shop said that they compressed air into the air intake and it would not hold. So, they said the turbo would not kick in if the intake isn’t building pressure.
Smoke test through the intake assembly: smoke only came out of the dipstick and oil fill cap. No clue if that's good or bad.
Boost leak test confirmed massive leaks all coming from the charge pipe to the throttle body. I bought 3x 2" shielded transition couplings from Lowes, cut the charge pipe in 3, and used the couplings to seal the damaged areas. Cost $38.00. Boost leak performed and was not losing pressure at an alarming rate any longer.
My vehicle, from a deadstart to 5000 RPM in WOT only pushed a maximum boost of 8 PSI. I am unfamiliar with a lot of this but I am under the impression I should be hitting 20.
Drove the car around, still triggered a P2261 code. Tomorrow, I will be installing a new bypass solenoid valve.
Amazon - GM Part
I will attach freeze frame data below.
Any information about this error code would be greatly appreciated, I am looking for any diagnostic work I can do to isolate the issue. I will be systematically replacing parts until the light disappears. I have scoured this forum, google, and youtube. I have found several posts about this error code and no information as to how to fix it.
