The P2564 Turbocharger Boost Control Position Sensor Low code sets when your ECM detects a voltage signal from the turbo boost control position sensor that falls below the expected calibrated range. In plain terms, the sensor that tells the computer where your turbo’s actuator or wastegate arm is sitting has dropped its signal to a

The P003B Turbocharger VGT Control Circuit Range code is one of the most misdiagnosed trouble codes we see come through the shop, and it costs owner-operators real money when it gets thrown at the wrong parts. This code lands on both Cummins and Ford diesel platforms, and it points to a problem in the variable

The P2263 Turbo Boost System Performance Code is one of the more frustrating diagnostic trouble codes a diesel tech can face because it points to a performance problem, not a hard failure. The ECM isn’t telling you a sensor is disconnected or a wire is grounded. It’s telling you the boost the turbo is actually

The P0243 Turbocharger Wastegate Solenoid A Malfunction code is one of the most misdiagnosed boost-control faults we see come through our shop, and nine times out of ten the truck ends up with a replaced turbo it never needed. This code points to an electrical or control problem in the wastegate boost-control solenoid circuit, not

The P0045 Turbocharger Boost Control Solenoid Circuit Open code is one of the most common boost-related faults we see come through the shop, and it trips up plenty of experienced techs because the name points you in the wrong direction. This is not a mechanical turbo failure code. It is an electrical circuit fault telling
