Side Airbag Sensor Circuit Range/Performance Problem (Left)
There's a problem with the left side airbag sensor's circuit performance.
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 left side airbag sensor isn't sending the right signals. This could mean the airbag might not deploy in a crash, which is dangerous.
What the computer is actually seeing
The airbag control module detects that the voltage or resistance values from the left side airbag sensor are outside the expected range, usually greater than 5 volts or less than 1 ohm.
What a healthy reading looks like
Voltage should be around 0.5 to 4.5 volts; resistance should be about 2 ohms to 5 ohms.
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 visible damage to the left side airbag sensor wiring and connectors. Ensure all connections are tight and clean.
- 2Verify the airbag sensor's resistance with a multimeter — it should be between 2 to 5 ohms. If it's out of range, replace the sensor.
- 3Inspect the wiring harness for shorts or opens. Measure voltage at the sensor connector with the key in the 'on' position; it should be between 0.5 to 4.5 volts.
- 4Clear the fault code and perform a road test to see if the code reappears. If it does, proceed to replace the airbag sensor.
Common causes
- Damaged wiring or connectors to the airbag sensor
- Faulty left side airbag sensor
- Water intrusion in the airbag module
- Corroded connectors

Frequently asked questions
Is it safe to drive with this code?
No, since it indicates a fault in the airbag system, the airbags may not deploy in case of an accident.
Will the code come back after repairs?
If the wiring and connectors are fixed properly and the new sensor is good, the code shouldn't return.
Why does this code sometimes pair with other codes?
Intermittent sensor issues or wiring problems can cause multiple fault codes involving different sensors to appear.
