B2BAC Daihatsu Sonica OBD Code

OBD/2 B2BAC error code description and symptoms.

Mass Air Flow (MAF) Sensor Intermittent The MAF sensor circuit is monitored by the PCM for sudden voltage (or air flow) input change through the comprehensive component monitor (CCM). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

Circuit High Input codes like B2BAC are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

If your transmission control system electrical check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system B2BAC and engine control unit are in charge of monitoring a bunch of different transmission control system electrical, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Daihatsu Sonica B2BAC OBD2 Code

A common cause of code B2BAC is the failure of Transmission Control System Electrical, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Faulty Intake Valve Timing Control Solenoid Valve
Faulty variable valve timing (VVT)
Intake Valve Timing Control Solenoid Valve harness is open or shorted
