P0651 2017 Honda CR-V Code - Sensor Reference Voltage 'B' Circuit Malfunction
Quick Answer
The Powertrain Control Module (PCM) is equipped with a voltage monitor (5 V power source) to supply a stable 5 V to each sensor as a reference voltage. Common causes include A/C pressure sensor VCC line short to power, Accelerator Pedal Position (APP) sensor VCC line short to power, Turbocharger VCC line short to power. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
