Airbag Crash Sensor Fault
The airbag control module has detected a fault in the crash sensor circuit.
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)
This means the car's airbag system isn't getting a proper signal from the crash sensor, which can happen if there's a wiring issue or the sensor itself has malfunctioned.
What the computer is actually seeing
The airbag control module monitors the voltage and resistance from the crash sensor. A fault indicates that the readings are outside the expected parameters, often showing open or short circuit conditions.
What a healthy reading looks like
The crash sensor should typically show a resistance within 2 to 5 ohms when properly connected and functional, and should not trigger a fault code lasting more than 0.1 seconds under normal conditions.
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.
- 1Check for any obvious wiring issues, like frays or cuts in the sensor wiring harness.
- 2Inspect the connectors for corrosion or loose connections that could affect signal integrity.
- 3Use a multimeter to measure resistance across the crash sensor; it should be within 2-5 ohms.
- 4If the resistance is out of range, replace the crash sensor and clear the code to see if it returns.
- 5If the resistance is okay, inspect the airbag control module for faults.
Common causes
- Bad crash sensor
- Wiring harness damage
- Corroded connectors
- Faulty airbag control module

Frequently asked questions
Is it safe to drive with this code present?
It's not recommended to drive with an airbag fault since the airbags may not deploy in a crash.
Will this code come back after clearing it?
If the underlying issue isn't resolved (like a wiring issue or bad sensor), it will likely return.
Why might this code pair with other codes?
Other codes may involve related components like the airbag control unit or other sensors in the system.
