Left Front Active Head Restraint Position Sensor Range/Performance Problem
Issues with the left front active head restraint system's position 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 checks the position of the head restraint for safety during a crash. If the sensor doesn't show the head restraint is moving properly or is stuck, this code pops up.
What the computer is actually seeing
The computer expects the position sensor to report a specific movement range, typically from 0 to 5 volts. If the voltage is out of this range or remains static, the fault code triggers.
What a healthy reading looks like
Position sensor voltage should swing between 0.5V to 4.5V depending on the head restraint position.
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 wiring harness and connectors around the head restraint. Look for corrosion or broken wires. If any damage is found, repair it and clear the code.
- 2Using a multimeter, check the voltage at the position sensor while moving the head restraint manually. Ensure it outputs a voltage change between 0.5V and 4.5V. If it stays the same, replace the sensor.
- 3If the sensor outputs correct voltage but the error code persists, inspect the mechanics of the head restraint to ensure it is not jammed or blocked. Repair any mechanical issues found.
Common causes
- Faulty position sensor
- Wiring issues to the sensor
- Head restraint mechanical blockage or failure
- Faulty control module

Frequently asked questions
Is it safe to drive with this code?
It's moderate severity, so you can drive, but fix it soon to ensure full safety during a crash.
Will this code come back after clearing it?
If the underlying issue isn't resolved, yes, the code will likely return.
Why does this code pair with others like B007A?
Codes often pair when multiple sensors or systems related to the same component have issues.
