Lateral Acceleration Sensor Fault
The lateral acceleration sensor has detected a fault.
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 car's computer is saying the sensor that detects side-to-side motion isn't working right.
What the computer is actually seeing
The computer expects a specific voltage signal from the lateral acceleration sensor, typically between 0.5V (no lateral force) to 4.5V (maximum lateral force), but it's getting a flat line or an out-of-range signal.
What a healthy reading looks like
Voltage should be between 0.5V and 4.5V under normal operation.
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 sensor wiring and connectors for damage or corrosion. Repair as needed. Decision: Was any damage found? Yes: Repair wiring; No: Proceed to step 2.
- 22. Check the lateral acceleration sensor output with a multimeter. Expected: 0.5V to 4.5V. Decision: Is the reading within range? Yes: Proceed to step 3; No: Replace the lateral acceleration sensor and retest.
- 33. Clear the code and take the vehicle for a test drive. Monitor live data for the sensor output. Decision: Does the code return? Yes: Check for ECU issues; No: Repair successful.
Common causes
- Defective lateral acceleration sensor
- Wiring or connector issues
- Calibration problems
- Faulty ECU
- Vibration or impact damage

Frequently asked questions
Can I still drive my car with this code?
Yes, but expect possible handling issues or traction control problems.
Will this code come back after clearing it?
It may, depending on the underlying issue—like a faulty sensor or wiring problem.
Does this issue tie in with traction control problems?
Yes, it often affects traction control systems since they rely on sensor data.
