What is a turbocharger boost control module?
In turbocharged internal combustion engines, a boost controller is a device sometimes used to increase the boost pressure produced by the turbocharger. It achieves this by reducing the boost pressure seen by the wastegate.
What causes a P0035?
The P0035 code is stored when the powertrain control module (PCM) perceives a problem with the turbocharger (or supercharger) bypass valve or its circuit.
How does a turbo bypass valve work?
A bypass valve is different from a blow-off valve because it doesn’t vent any air to atmosphere. Instead, it recirculates the air back into the intake before the turbo or supercharger inlet, but after the airflow sensor. This design keeps pressure much more consistent.
How much is a boost sensor?
The average boost pressure sensor replacement cost is between $175 and $200. However, this cost can vary depending on the vehicle you drive and where you take it for repairs.
