Front Impact Sensor Circuit Range/Performance Problem (Left)
Front impact sensor on the left side has a range or performance issue.
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 computer's not getting the right signals from the left front impact sensor, which helps determine if airbags should deploy during a crash.
What the computer is actually seeing
The computer monitors the left impact sensor's resistance and voltage. It expects a consistent voltage signal (typically around 2.5V when idle). If this fluctuates or is out of the expected range, it will set code B000C.
What a healthy reading looks like
Expected voltage from the sensor should be around 2.5V at rest (no impact).
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.
- 1Inspect the wiring and connector to the left front impact sensor for damage or corrosion.
- 2Verify voltage at the connector with the key on (engine off). Voltage should be around 2.5V. If not, check for wiring issues. Decision Point: Is voltage correct? Yes: Go to step 3. No: Repair wiring or replace connector.
Common causes
- Corroded or damaged wiring to the sensor
- Faulty left front impact sensor
- Poor connector contact or corrosion
- Faulty airbag control module
Typical repair cost
$$$

Frequently asked questions
Is it safe to drive with this code?
It's best to fix this soon; while the vehicle may drive okay, the airbags may not deploy in a crash.
Will this code come back after clearing?
If the underlying issue is not resolved, yes, the code likely will return.
Why does this code appear with other codes?
Codes often relate to similar systems; if the impact sensor fails, it may trigger related faults in the airbag system.
