B0428 Bugatti Type 101 OBD Code

OBD/2 B0428 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code B0428

One example of this would be when an automatic vehicle in placed in gear. To prevent the added drag from the torque converter and transmission from reducing the idling speed, the PCM will command the idle control valve to allow more air to enter the engine, while at the same time, adjusting the injector pulse width to inject more fuel to suit the increased amount of air. Note that the idle air control valve is closed by the PCM when the throttle plate is opened to prevent excess air from entering the engine.

B0428 Bugatti Type 101 Error Code Repair Process :

If your vehicle failed a B0428 test and the B0428 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses engine coolant temperature (ect) sensor circuit intermittent high voltage/iat - b circuit high input a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look engine coolant temperature (ect) sensor circuit intermittent high voltage/iat - b circuit high input: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Bugatti Type 101 B0428 OBD2 Code

A common cause of code B0428 is the failure of Engine Coolant Temperature (ECT) Sensor Circuit Intermittent High Voltage/IAT - B Circuit High Input, but there are several other possible causes as well, such as ;

• Continuous oil flow to the VCT piston chamber
• Faulty Variable Camshaft Timing (VCT) position solenoid
• Faulty Crankshaft Position Sensor (POS)
• Ignition coils circuit poor electrical connection
