P16Bb Fault Code: Understanding The Description And Troubleshooting Tips
The P16BB fault code refers to a problem with the alternator ‘B’ terminal circuit’s low voltage. The alternator is responsible for generating electricity to power the electrical system and charge the battery.
The alternator control mode, controlled by the Powertrain Control Module (PCM), ensures the alternator maintains voltage target values of 14.5 V and 12.5 V. The PCM receives the alternator output signal, which varies based on factors such as battery charge, electrical load, and engine speed. When the engine speed reaches a specified value and the IGP terminal voltage falls below a set value while the alternator is in the 14.5 V mode, and this condition persists for a specific duration with the alternator power generation within the set range, the PCM detects a malfunction.
This triggers the P16BB fault code, indicating a problem with the alternator ‘B’ terminal circuit’s low voltage. It is important to address this issue promptly to ensure proper functioning of the electrical system and battery charging.
