P0180: Fuel Temperature Sensor A Circuit
Can you still drive? Yes, this is a low-severity code. The ECM will use a default fuel temperature value. You may see a minor impact on fuel economy but the vehicle is safe to drive.
What Does P0180 Mean?
Code P0180 indicates a malfunction in the fuel temperature sensor A circuit. The fuel temperature sensor measures the temperature of fuel in the supply system, which the ECM uses to calculate fuel density and adjust injection pulse width. P0180 is set when the sensor signal is outside the valid range or is electrically faulty.
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.

Frequently Asked Questions
Is P0180 common on diesel engines?
Yes, P0180 is more commonly seen on diesel vehicles because fuel temperature has a greater impact on diesel fuel density and injection quantity. Gasoline vehicles may also have this sensor but it is less common.
Can I drive with P0180 code?
Yes, you can drive normally. The ECM substitutes a default fuel temperature value. Fuel economy may be slightly off, but there is no risk of engine damage.
