P0182 Code - Fuel Temperature Sensor Circuit Low Input

Quick Answer

The P0182 code indicates that the fuel temperature sensor circuit is registering a low input signal. Common causes include Faulty fuel temperature sensor, Damaged wiring or connectors in the sensor circuit, Corrosion or poor connections in the sensor circuit. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0182 Description

The P0182 code indicates that the fuel temperature sensor circuit is registering a low input signal. This sensor is responsible for monitoring the temperature of the fuel in the vehicle's fuel tank. The fuel temperature sensor plays a crucial role in helping the engine control module (ECM) adjust the air-fuel mixture for optimal combustion. When the sensor detects a low input signal, it means that the fuel temperature is lower than expected, which can lead to issues with fuel efficiency, engine performance, and emissions.

Common Causes of P0182

  1. Faulty fuel temperature sensor
  2. Damaged wiring or connectors in the sensor circuit
  3. Corrosion or poor connections in the sensor circuit
  4. ECM software or hardware issues affecting sensor readings
  5. Extreme temperature fluctuations affecting sensor performance

Symptoms of P0182

  1. Decreased fuel efficiency
  2. Rough idling
  3. Hesitation during acceleration
  4. Engine stalling
  5. Check engine light illuminated

How to Fix P0182

  1. Use an OBD-II scanner to confirm the P0182 code and verify the low input signal from the fuel temperature sensor.
  2. Inspect the wiring and connectors in the sensor circuit for any damage, corrosion, or loose connections.
  3. Test the fuel temperature sensor's resistance and compare it to manufacturer specifications to determine if it is faulty.
  4. If the sensor is faulty, replace it with a new, OEM-quality sensor and ensure proper installation and calibration.
  5. Clear the trouble code from the ECM's memory and perform a test drive to verify that the issue has been resolved.

Cost to Fix P0182

The typical repair costs for addressing a P0182 code related to the fuel temperature sensor circuit low input can vary depending on the specific vehicle make and model, as well as the location and labor rates of the auto repair shop. In general, replacing a faulty fuel temperature sensor and addressing any related wiring issues can cost between $150 to $300 for parts and labor. However, it's important to keep in mind that additional diagnostic time or unforeseen complications during the repair process may increase the overall cost. It is recommended to consult with a qualified mechanic or auto repair shop to get a more accurate estimate based on your vehicle's specific needs.

When is the Code Detected?

An excessively low voltage from the sensor is sent to ECM.
