SRS (Supplemental Restraint System) Passenger Side Airbag Sensor Circuit Range/Performance Problem
Passenger side airbag sensor circuit issue detected.
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 airbag system is telling the computer there's a problem with the sensor that detects if someone is in the passenger seat. If it thinks the sensor isn't working right, the airbag may not deploy in a crash.
What the computer is actually seeing
The Airbag Control Module (ACM) monitors the resistance of the passenger airbag sensor. It expects a certain range of resistance values (usually less than 5 ohms when the seat is occupied).
What a healthy reading looks like
Resistance should be between 1 to 4.5 ohms with an occupied seat; higher resistance indicates an issue.
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. Inspect the passenger seat area for any obvious damages or obstructions. Decision Point: If damaged, repair or replace as necessary.
- 22. Check the wiring harness and connectors for corrosion or loose connections around the airbag sensor. Decision Point: If there's damage, repair or replace the wiring.
- 33. Use an OBD-II scanner to check the resistance readings from the airbag sensor while the seat is occupied. Measure the resistance. Decision Point: If resistance is out of the expected range (1-4.5 ohms), replace the sensor.
- 44. Verify that the airbag module is properly grounded and powered. Decision Point: If not, check the ground and power circuits for issues.
- 55. After addressing any found issues, clear the codes and do a test drive. Monitor to see if the code returns. Decision Point: If the code returns, further investigate the ACM or consider professional diagnostics.
Common causes
- Faulty airbag sensor
- Damaged or corroded wiring
- Disconnected or loose connectors
- Seat cushion damage
- Incorrectly installed or aftermarket seat cover
