Lateral Acceleration Sensor Performance
The control module detects an issue with the lateral acceleration 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 car's computer isn't getting the right signals from the sensor that measures side-to-side movement, which can affect stability control.
What the computer is actually seeing
The lateral acceleration sensor should output a voltage signal within a specific range based on the vehicle's movement. If the signal is not within that range, the computer sets this code.
What a healthy reading looks like
Signal voltage typically ranges from 0.5V (no lateral movement) to 4.5V (maximum lateral acceleration).
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 wiring and connectors between the lateral acceleration sensor and the control module for damage or corrosion. If found, repair or replace accordingly.
- 22. Measure the voltage output of the lateral acceleration sensor while gently moving the vehicle side to side. Ensure it should range from 0.5V to 4.5V. If out of range, the sensor may need replacement.
- 33. Check for any signs of previous repairs or components that were replaced near the sensor. If the sensor was recently replaced, verify if it was calibrated correctly after installation.
Common causes
- Faulty lateral acceleration sensor
- Wiring issue or short to ground/open circuit
- Poor connection at the sensor or module.
- Calibration issue after part replacement.

Frequently asked questions
Is it safe to drive with this code?
While you can drive, systems like stability control may be impaired, affecting handling in adverse conditions.
Will the code come back after clearing it?
Yes, if the underlying issue isn't resolved, the code will return after a full drive cycle.
Why does this code appear with similar codes?
These codes often indicate issues with the same sensor or related systems, and diagnosing one can reveal others.
