It's crucial not to confuse this with a related, but different, generic powertrain code: . While P2729 is also a control circuit code, it deals with a "Pressure Control Solenoid" within the transmission. That's a powertrain issue. Here, your B272914 is a body systems issue.
Often cheaper, but some users report "ghost" alerts where the system beeps at nothing because the sensor sensitivity is off. How to Diagnose it Yourself : In standard automotive electronics, the suffix "14"
Nissan Advanced Driver Assistance Systems (ADAS) use a series of ultrasonic sonar sensors embedded in the front and rear bumpers. Code . The sub-fault code "-14" is an automotive standard sub-type indicating a circuit continuity failure (typically an open circuit or shorted connection to ground).
When this code is active, you will almost certainly notice one or more of these symptoms: Step 1: The "Tick" Test This is not
