P0182: Fuel Temperature Sensor A Circuit Low Input
Can you still drive? Yes, driving is safe. The ECM will use a default fuel temperature value, which may slightly reduce efficiency.
What Does P0182 Mean?
Code P0182 indicates that the fuel temperature sensor circuit is reporting a voltage that is below the minimum acceptable range. This low voltage reading typically corresponds to an extremely high temperature reading that is not realistic, suggesting a wiring fault or sensor failure rather than an actual temperature condition.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

- Short to ground in the sensor wiring
- Failed fuel temperature sensor
- Corroded or water-damaged connector
- Damaged wiring harness
Symptoms
- Check engine light on
- Slightly rough idle
- Reduced fuel economy
- Possible hard starting
Diagnostic Steps
- 1Read freeze frame data and note the fuel temperature value
- 2Inspect the sensor connector for water intrusion or corrosion
- 3Disconnect the sensor and check if the code changes to high input
- 4Measure sensor resistance and compare to the temperature-resistance chart
- 5Repair wiring or replace the sensor as needed

Frequently Asked Questions
What does low input mean on a temperature sensor?
Low voltage input on a temperature sensor typically means the ECM is seeing a reading that corresponds to an unrealistically high temperature, usually caused by a short to ground in the wiring.
Can I drive with P0182 until my repair appointment?
Yes, this code does not pose a safety risk. The engine management system will substitute a default value for fuel temperature.
