Driver Frontal Impact Sensor Circuit Fault
There's a fault in the circuit for the driver's frontal airbag sensor.
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 driver's airbag sensor isn't working right, which is important for the airbag to deploy in a crash.
What the computer is actually seeing
The airbag control module sees an open circuit or short in the driver's frontal impact sensor, which should normally show a resistance of about 2-10 ohms.
What a healthy reading looks like
A properly functioning driver's frontal impact sensor should have a resistance reading between 2-10 ohms when measured across the sensor terminals.
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. Check the wiring and connectors at the driver's frontal impact sensor. Look for signs of damage or corrosion. If any issues found, repair them and retest.
- 22. Measure resistance across the impact sensor terminals. It should be between 2-10 ohms. If not, replace the sensor and retest.
- 33. Check the airbag control module for any additional codes related to the airbag system. If no other codes exist, but the issue persists after sensor replacement, consider the control module itself as faulty.
Common causes
- Damaged or corroded wiring
- Faulty impact sensor
- Connector issues
- Faulty airbag control module

Frequently asked questions
Is it safe to drive with this code?
No, it's not safe. The airbag may not deploy in an accident.
Will this code come back after clearing?
If the underlying issue isn't fixed, the code will return.
Why does this code appear with other airbags codes?
Multiple airbag codes may indicate a common problem in the airbag system, like shared wiring or control module failure.
