Passenger Airbag Sensor Fault
Indicates a problem with the passenger airbag sensor system.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The passenger airbag sensor is designed to detect whether there's someone sitting in the passenger seat, and if it's not working properly, it can prevent the airbag from deploying in an accident.
What the computer is actually seeing
The system monitors the passenger airbag sensor circuit for resistance values. If the resistance is outside of the expected range, it triggers this code.
What a healthy reading looks like
Resistance should typically be around 2-4 ohms when a seat is occupied; open or short circuits will cause this code to set.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Visually inspect the wiring and connectors in the passenger airbag system. Look for any signs of damage, corrosion, or loose connections. If any are found, repair or replace as necessary. Decision: Are all connections good? If yes, proceed to step 2; if no, fix the issues and clear the code, then test drive.
- 22. Check the resistance of the passenger airbag sensor while pressuring the seat (simulate occupancy). Use a multimeter; if resistance is not within 2-4 ohms, the sensor is likely faulty. Decision: Is the resistance in range? If yes, proceed to step 3; if no, replace the sensor and clear the code.
- 33. Scan the airbag control module for further codes. If additional fault codes exist, address them accordingly. Decision: Are there additional codes? If yes, follow the diagnostics; if no, proceed to step 4.
- 44. If the issue persists after sensor replacement, consider a faulty airbag control module. Consult repair data for reprogramming or replacement. Decision: System now functioning? If yes, end diagnostics; if no, a module replacement may be necessary.
Common causes
- Faulty passenger airbag sensor
- Wiring issues in airbag circuit
- Connector problems at the airbag module or sensor
- Faulty airbag control module

Frequently asked questions
Is it safe to drive with this code?
While the vehicle is drivable, the airbag system is compromised, making it unsafe in case of an accident.
Will this code come back after clearing it?
If the underlying issue is not fixed, the code is likely to return.
Can other faults cause this code to appear?
Yes, wiring issues or connector faults can cause this code even if the sensor is functioning normally.
