Low Side Voltage Sensor Circuit
Indicates a low voltage condition in the 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 computer is seeing less voltage than it should from the sensor, which means it might not be working right, or there's a wiring issue.
What the computer is actually seeing
The module expects a voltage between 0.5V to 4.5V based on sensor input; anything significantly lower triggers the code.
What a healthy reading looks like
Expected voltage range for the circuit should be between 0.5V and 4.5V, based on the specific sensor's function.
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 the wiring and connector for damage or corrosion. Ensure connections are tight and free of debris.
- 2Use a multimeter to measure voltage at the sensor connector: should be within 0.5V to 4.5V. Is it below 0.5V?
- 3If voltage is low, trace back the wiring for continuity and check for breaks or shorts.
- 4If wiring checks out, replace the sensor and clear the code. Re-test to ensure the issue is resolved.
Common causes
- Damaged wiring or connectors in the sensor circuit
- Faulty sensor itself
- Open circuit or short to ground in wiring
