Left Front Position Sensor Circuit Short to Battery
There's a short circuit in the left front position sensor circuit.
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 position sensor for the left front side is sending a constant high voltage, which means there's a problem in the wiring or the sensor itself.
What the computer is actually seeing
The vehicle's computer sees a voltage reading that is above the normal operating range, indicating a short to battery voltage in the circuit for the left front position sensor.
What a healthy reading looks like
Normal voltage for the left front position sensor should be between 0.5 to 4.5 volts depending on the state (0.5V for minimum position, 4.5V for maximum).
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 for the left front position sensor for any visible damage, shorts, or corrosion.
- 22. Check the voltage at the position sensor connector with the ignition on (should be 0.5-4.5V). If above 4.5V, go to step 3. If normal, suspect a faulty sensor.
- 33. Disconnect the sensor and check the voltage at the wire harness side of the connector. If it reads over 4.5V, trace the wiring back to the ECU for shorts.
- 44. If wiring checks out, replace the left front position sensor and retest.
Common causes
- Shorted wiring in the left front position sensor circuit
- Faulty position sensor
- Bad connector or corroded terminals
