Left Front Door Mail Slot Sensor Circuit Low
The left front door mail slot sensor is reporting low voltage.
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 sensor that knows if the mail slot in the driver's door is working properly is sending low voltage signals, which can mean a problem with the sensor itself or the wiring to it.
What the computer is actually seeing
The computer expects to see voltage between 5.0V and 12.0V from the mail slot sensor circuit when functioning correctly. A reading below 2.5V indicates a fault.
What a healthy reading looks like
Normal operation: 5.0V - 12.0V; Fault threshold: below 2.5V.
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 connectors for visible damage or corrosion at the left front door.
- 2Using a multimeter, measure the voltage at the mail slot sensor connector with the door open. Expected value: 5.0V - 12.0V. If low, proceed to the next step.
- 3Inspect the circuit for continuity by using a multimeter with the door closed and key on. If continuity is not present, locate and fix the open circuit.
- 4If voltage is correct and continuity is present, replace the mail slot sensor and retest.
Common causes
- Faulty mail slot sensor
- Damaged wiring or connectors
- Short to ground in the circuit
- Open circuit due to broken wire
