  • The diagnostic trouble code (DTC) P0182 stands for “Fuel Temperature Sensor ‘A’ Circuit Low.” The powertrain control module (PCM) will log this code if it detects a lower-than-normal voltage signal from the fuel temperature sensor.
  • Common causes of the P0182 code are a bad fuel temperature sensor, wiring problems, outdated PCM software, or a malfunctioning PCM.
  • A vehicle that sets a P0182 code can show symptoms like an illuminated check engine light, rough running, and misfiring.

Your vehicle has a number of sensors that work together to make sure it is operating properly. The fuel temperature sensor is one of these sensors. The fuel temperature sensor might become defective with time, just like any other sensor in your vehicle.

P0182 is a generic trouble code that refers to a problem within this sensor.  Learn more by reading this article.

What Does the P0182 Code Mean?

Diagnostic trouble code P0182 stands for “Fuel Temperature Sensor A Circuit Low Input.” The code is set once the PCM detects a voltage signal from the sensor that’s lower than expected.

The fuel temperature sensor might become defective with time, just like any other sensor in your vehicle.

The PCM gets an accurate fuel temperature analysis from the fuel temperature sensor. This sensor is typically small in size and located somewhere between the fuel tank and the fuel injectors. It sends data to the PCM using voltage representations.

The PCM will set code P0182 if it detects an implausible signal from the fuel temperature sensor.

Note: The definition of code P0182 might be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.

How to Diagnose the P0182 Code

DTC P0182 can occur in a variety of vehicles. This does not, however, imply that there is a universal solution to this problem. Keep in mind that vehicles can be structured differently depending on the manufacturer.

Take your vehicle to an auto repair shop and have it diagnosed by a mechanic if you’re unfamiliar with vehicle speed sensors. Otherwise, here is a video that outlines what the diagnostic process might involve:

How to Fix the P0182 Code

Repairs can be difficult if you don’t have the necessary tools and skills. We recommend taking your vehicle to a professional if you are unfamiliar with vehicle repair.

If you’re a seasoned DIYer looking to save money, we recommend doing your homework and brushing up on vehicle-specific repair knowledge.

Repair manuals or a subscription to an online repair database can provide you with information on the precise diagnostic and repair process to remove code P0182.
