September 22, 2020 P0045 Code: Turbo/Supercharger Boost Control A Circuit OpenDiagnostic Trouble Code (DTC) P0045 stands for “Turbo/Supercharger Boost Control A Circuit Open.” The code triggers once the powertrain control module (PCM) detects a potential open circuit in the boost control solenoid (or VGT actuator) or its circuit.
September 15, 2020 P2101 Code: Throttle Actuator “A” Control Motor Circuit Range/PerformanceTo understand the code more, we have to discuss the basics of an ETC system. Basically, your vehicle’s ETC system controls your throttle valve opening. Your PCM then uses input from Accelerator Pedal Position (APP) sensors and throttle position sensors when analyzing ETC operations, including how to adjust the September 15, 2020 P0505 Code: Idle Control SystemOn most older vehicles, the idle control system relies on an idle air control valve (IAC) on or near the throttle body. The IAC meters the amount of bypass air around the throttle plate to sustain the idle speed.
If the PCM perceives a problem with the idle air control system,
