B0092 OBD2 Code Guide
B0092 is a body / srs diagnostic trouble code. Use this hub to understand the plain meaning, the first checks to run, and which vehicle-specific guides may be more useful before replacing parts.
Passenger Presence Detection Performance
Code B0092 indicates a performance fault within the Passenger Presence Detection (PPD) system, which is a critical component of the Supplemental Restraint System (SRS). This system is responsible for detecting the presence and weight of a front passenger to determine the appropriate airbag deployment strategy, including whether to enable or disable the passenger front airbag. A performance fault suggests the system is not accurately sensing or reporting passenger status, potentially compromising occupant safety during a collision.
Code verification standard
B0092 is published with SAE J2012 / ISO 15031-6 code structure plus OBD2 B0092 diagnostic context.
First checks
- - Read all stored and pending codes before clearing anything.
- - Save freeze-frame data so you know speed, load and temperature when the code set.
- - Inspect wiring, connectors, fuses, hoses and obvious leaks tied to the named system.
- - Compare live data against realistic values before buying sensors or modules.
- - Clear the code only after repair and complete a drive cycle to confirm it does not return.
B0092 diagnostic path
- 1Connect an advanced scan tool capable of accessing the SRS module and confirm the B0092 code. Check for any other related SRS or PPD system codes that might provide additional context.
- 2Visually inspect the passenger seat area, specifically the seat cushion and its underside, for any signs of damage, spills, foreign objects, or modifications that could affect the PPD sensor mat.
- 3Carefully inspect the wiring harness and connectors leading to the PPD sensor mat and the PPD control module (if separate) for fraying, corrosion, loose connections, or damage. Ensure proper seating of all connectors.
- 4Using the scan tool, monitor the PPD system's live data parameters, such as passenger weight readings or occupant classification status, while applying varying pressure to the passenger seat. Compare readings to specifications.
- 5If available, attempt a PPD system recalibration or re-initialization procedure using the scan tool. This can sometimes resolve performance issues if the system has lost its baseline calibration.
Verify before repair
- - Repair or replace damaged wiring or corroded connectors affecting the PPD sensor mat or module.
- - Replace the faulty Passenger Presence Detection (PPD) sensor mat located within the passenger seat cushion.
- - Replace the Passenger Presence Detection (PPD) control module if it's determined to be internal to the module and not the sensor mat.
- - Perform a PPD system recalibration or re-initialization using a manufacturer-specific scan tool.
