P0182 Code – What Does It Mean & How To Fix It

This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it.


A problem with the fuel temperature sensor circuit is referred to in the P0182 DTC code. The monitoring of the temperature in the fuel tanks shall be carried out by a Fuel Temperature Sensor. Certain vehicles are covered by this code, which is not applicable to all vehicle types and models. It is essential to consult the vehicle’s documentation or seek advice from a car expert in order to be able to interpret it correctly.


The voltage signal from the fuel temperature sensor is either greater or lower than the range specified by the manufacturer when the P0182 code is activated. The sensor’s performance may be affected in this way, which might result in erroneous fuel temperature readings.


The P0182 DTC code may appear as a result of several factors:

  • Fuel temperature sensor issue: A fuel temperature sensor issue may result in erroneous voltage readings, activating the code.
  • Wiring Problems: Corroded or damaged wiring in the circuit that houses the fuel temperature sensor might impede signal transmission and result in erroneous readings.
  • Fuel Temperature Sensor Position: A fuel temperature sensor’s capacity to monitor fuel temperature properly might be impacted by improper mounting or installation.
  • Fuel Contamination: Fuel contamination might impair sensor function and result in false readings.


The following signs and symptoms might be present when the P0182 DTC code is present:

  • Illuminated Check Engine Light: The most noticeable symptom is the illumination of the check engine light on the vehicle’s dashboard.
  • Erratic Fuel Gauge: The fuel gauge may provide inconsistent or erroneous readings of the fuel level.
  • Fuel economy Issues: Inaccurate fuel temperature measurements may have an impact on the vehicle’s fuel economy.
  • Engine Performance Issues: The engine may occasionally have performance problems, such as hesitation or rough idling.


A competent technician must use a methodical methodology to accurately diagnose the P0182 DTC code. The diagnostic procedure might entail:

  • OBD-II Scanner: Using an OBD-II scanner, the mechanic can retrieve the trouble code and other relevant data from the vehicle’s onboard computer.
  • Visual Inspection: The fuel temperature sensor and its wiring should be carefully inspected visually for any obvious rust or damage.
  • Testing the Fuel Temperature Sensor: The technician may do tests to check the voltage output and reaction time of the fuel temperature sensor to changes in fuel temperature.
  • Addressing Related Problems: Prior to concentrating on the fuel temperature sensor check, it is crucial to address any concerns about fuel contamination or other related issues.

Common mistakes

Common errors to avoid when handling the P0182 code include:

  • Ignoring Other Codes: P0182 may be accompanied by other relevant codes, and failing to pay attention to them may cause you to miss important problems.
  • Replacing parts too soon: To prevent wasting money, it’s important to undertake a thorough diagnosis before replacing any components.
  • Ignoring Fuel Contamination: To ensure accurate fuel temperature sensor readings, fuel contamination must be checked.

How serious is this?

The seriousness of the P0182 DTC code is influenced by a number of factors, such as the scope of the problem and driving conditions. While this code may be used by the vehicle on its own, a failure to recognize it could result in incorrect fuel level readings and an energy efficiency problem.

What repairs can fix the code?

repair manuals

The following repairs can deal with the P0182 DTC code, depending on the diagnosis:

  • Replacing the Fuel Temperature Sensor: If the fuel temperature sensor is broken, it may be fixed by swapping it out for a brand-new, working one.
  • Repairing Wiring: You may get the fuel temperature sensor circuit’s signal transmission working again by fixing any corroded or broken wiring.
  • Checking for Fuel Contamination: The fuel temperature sensor will give accurate results if the gasoline is clear of impurities.

Related codes

Other related DTC codes include P0180 (Fuel Temperature Sensor A Circuit) and P0181 (Fuel Temperature Sensor A Circuit Range/Performance). These codes may provide additional insights into the fuel temperature sensor’s overall performance.


A possible problem in the fuel temperature control circuit is identified by the P0182 DTC code. Maintaining precise fuel temperature readings, fuel efficiency, and total engine performance can be maintained with prompt diagnosis and correct repairs. In order to provide a satisfactory and troubleless driving experience, if you are confronted with this code, the correct diagnosis and solution to the problem should be sought by professional automobile technicians.
