Linear Accelerometer Malfunction
The system detected a problem with the linear accelerometer.
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 uses a sensor to measure acceleration forces in three directions. When this sensor has a problem, it can affect stability and traction control systems.
What the computer is actually seeing
The linear accelerometer sends voltage signals representing acceleration on three axes. If the voltage is out of the expected range, the computer identifies this as a malfunction.
What a healthy reading looks like
The normal voltage should be between 0.5V and 4.5V depending on the vehicle's acceleration in any direction.
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 or corrosion in connectors and wiring related to the linear accelerometer.
- 2Inspect the accelerometer for any physical damage or dislocation.
- 3With the vehicle off, measure the voltage at the accelerometer connector while disconnecting and reconnecting—should be stable between 0.5V and 4.5V.
- 4If values are out of range, replace the accelerometer. If within range, check for software updates or faults in the control module.
Common causes
- Faulty linear accelerometer
- Wiring issues or shorts in the accelerometer circuit
- Bad connectors or corroded terminals
- Software glitches in the vehicle's control module

Frequently asked questions
Is it safe to drive with this code active?
Yes, but be cautious; stability and traction control might not function properly.
Will this problem go away on its own?
Unlikely. You should diagnose and repair it to ensure safety.
Why is this code paired with other fault codes?
Issues with the accelerometer can affect multiple systems that rely on acceleration data, leading to multiple codes being triggered.
