Honda Civic B0092: Passenger Presence Detection Performance diagnosis
Code verification standard
B0092 is published with SAE J2012 / ISO 15031-6 code structure plus Honda Civic diagnostic context.
This page covers meaning, symptoms, first checks, live data, misdiagnosis risk, and repair verification.
What does this mean?
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.
How serious is this code?
A B0092 code indicates a compromised Passenger Presence Detection system, which is vital for proper airbag deployment. In the event of a collision, the passenger front airbag may not deploy as intended (either deploying unnecessarily or failing to deploy when needed), significantly increasing the risk of injury to the front passenger. It is strongly recommended to have this issue diagnosed and repaired promptly.
Diagnostic system: Body, SRS, restraint, lighting, and comfort systems
On a Honda Civic, the B0092 code should be diagnosed as part of the body, srs, restraint, lighting, and comfort systems group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Honda Civic
- Damaged, chafed, or broken wiring harness
- Corroded or loose electrical connector
- Weak or failing battery
- Internal PCM/ECM failure
- PCM/ECM software needs update (TSB)
- Low A/C refrigerant charge
- Faulty A/C compressor or clutch
Symptoms to Watch For
- Airbag or SRS warning light is on
- Multiple warning lights or module communication warnings
- Battery draining or low voltage warning
- Engine cranks but won't start
- Cruise control not functioning
- Check Engine Light is illuminated
- A/C system not cooling properly
Before replacing parts, check these first
- Scan body/SRS modules with a tool that can access non-powertrain systems.
- Check battery voltage, fuses, grounds, seat connectors, restraint wiring, and water intrusion.
- Do not probe airbag circuits with unsafe test equipment; follow service information.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.
Live data to compare
- Freeze-frame conditions
- Related codes
- Circuit voltage and continuity
How to Diagnose
Common Mistakes
Clearing SRS/body codes without fixing connector, power, ground, or module communication faults first. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.
Repair verification
After the repair, clear B0092, complete a drive cycle, and confirm the monitor runs without the code returning. Save the before/after scan report if the vehicle needs emissions inspection.
Frequently Asked Questions
Can I drive with the B0092 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the B0092 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the B0092 code, your Honda will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for B0092?
Scan body/SRS modules with a tool that can access non-powertrain systems. Check battery voltage, fuses, grounds, seat connectors, restraint wiring, and water intrusion. Do not probe airbag circuits with unsafe test equipment; follow service information.

Repair Estimate
Fuse, connector, wiring, cleaning, or basic inspection
Major component replacement after live data and circuit tests confirm failure
Connector, fuse, and wiring fixes may be affordable; airbag, seat occupancy, or BCM work can require professional tooling and calibration.
DIY Difficulty
Can usually be performed at home with basic hand tools.
