Common Causes of P0182

Parts most likely causing this code, ranked by probability

Fuel Temperature Sensor70% likely

The fuel temperature sensor itself has failed internally, sending an incorrect low voltage signal to the engine computer.

70% of P0182 cases are fixed by replacing this part

Shop
Wiring or Connector25% likely

Damaged, corroded, or open wiring or a faulty connector to the fuel temperature sensor prevents a correct signal from reaching the engine computer.

25% of P0182 cases are fixed by repairing wiring or connector issues

Shop
Powertrain Control Module (PCM)5% likely

A rare internal fault within the engine computer can cause it to misinterpret or incorrectly process the fuel temperature sensor signal.

Check These First (Before Buying Parts)

  • Visually inspect the fuel temperature sensor and its wiring for any obvious signs of damage, fraying, or corrosion.
  • Ensure the connector to the sensor is securely attached and free of debris.

How to Diagnose P0182

  1. 1Visually inspect the fuel temperature sensor and its wiring for any obvious damage, corrosion, or loose connections.
  2. 2Using a multimeter, check the resistance of the fuel temperature sensor at various fuel temperatures (if accessible) and compare to manufacturer specifications.
  3. 3With the ignition on, check the voltage at the fuel temperature sensor connector to ensure proper reference voltage and ground are present.
  4. 4Use a scan tool to monitor the fuel temperature sensor reading in live data; look for an implausible low reading or no reading at all.

P0182 on Popular Vehicles

Toyota Camry

2007-2024

On many Camry models, the fuel temperature sensor is part of the fuel pump assembly located inside the fuel tank. Accessing it requires removing the rear seat and/or dropping the fuel tank.

70% fixed by replacing the fuel temperature sensor (often with the fuel pump module)

Honda Accord

2003-2024

Similar to other vehicles, the fuel temperature sensor on Honda Accords is typically integrated into the fuel pump module. Wiring issues are less common but should be checked thoroughly before replacing the module.

70% fixed by replacing the fuel temperature sensor (often with the fuel pump module)

Ford F-150

2004-2024

For Ford F-150 trucks, the fuel temperature sensor is almost always part of the fuel pump module. This means a sensor replacement involves dropping the fuel tank, which is a more involved repair.

Frequently Asked Questions

What does P0182 mean?

P0182 indicates that the engine's computer is receiving a low voltage signal from the fuel temperature sensor, suggesting the fuel is extremely cold or there's an electrical problem with the sensor circuit.

Can I drive with P0182?

Yes, you can drive safely with P0182. The vehicle will likely run in a 'limp home' mode or use a default fuel temperature value, which can cause reduced performance and fuel economy. Fix this within 1-2 weeks to prevent further issues.

Will P0182 clear itself?

No, P0182 will not clear itself. The Check Engine Light will remain on until the underlying fault with the fuel temperature sensor or its circuit is repaired and the code is cleared with a scan tool.

How do I fix P0182 myself?

Start by visually inspecting the fuel temperature sensor and its wiring for damage. If the wiring looks good, test the sensor's resistance with a multimeter. If the sensor is faulty, replace it. If the sensor is integrated into the fuel pump module, you will need to replace the entire module.

How much does it cost to fix P0182?

A DIY fix for P0182 typically costs $20-$100 for a new fuel temperature sensor. Professional repair at a shop costs $120-$400, including parts and labor.

P0182 keeps coming back - why?

If P0182 keeps returning, it means the root cause was not addressed. This often points to an intermittent wiring issue, a faulty connector, or a misdiagnosis where the sensor was replaced but the actual problem was elsewhere in the circuit or, rarely, the PCM.

Will P0182 fail emissions/smog test?

Yes, P0182 will cause your vehicle to fail an emissions or smog test. Any active Check Engine Light indicates a fault in the emissions system, which prevents passing the inspection.

What's the difference between P0182 and P0183?

P0182 indicates a 'low input' from the fuel temperature sensor, meaning the voltage signal is too low (suggesting extremely cold fuel or an open circuit). P0183 indicates a 'high input,' meaning the voltage signal is too high (suggesting extremely hot fuel or a short circuit).

P0182 on Ford F-150?

On many Ford F-150 models, the fuel temperature sensor is integrated into the fuel pump assembly inside the fuel tank. This means replacing the sensor often requires dropping the fuel tank and replacing the entire fuel pump module.

Questions to Ask Your Mechanic

Did you check the resistance of the fuel temperature sensor at different temperatures?

Good answer: Yes, I measured the resistance and compared it to the factory specifications. It was out of range, indicating a faulty sensor.

What did you find when you inspected the wiring and connector to the fuel temperature sensor?

Good answer: I found no visible damage or corrosion on the wiring or connector. I also performed a continuity test to confirm the circuit is intact.

Cost of Waiting

Ignoring P0182 can lead to continued poor fuel economy, reduced engine performance, and potentially hard starting, especially in cold weather. While it won't cause immediate catastrophic failure, it impacts drivability and emissions.

Tools You'll Need

  • OBD-II Scan Tool
  • Multimeter
  • Basic Hand Tools (sockets, wrenches)
  • Wire strippers/crimpers (if repairing wiring)

P0182 is a common sensor code. Most repairs are straightforward, involving a sensor replacement, and your vehicle will return to normal performance and fuel economy afterward.

Your Next Steps

1

Step 1: Visually inspect the fuel temperature sensor and its wiring for any damage or loose connections. Clear the code and see if it returns.

2

Step 2: If the code returns, use a multimeter to test the resistance of the fuel temperature sensor. Compare your readings to the vehicle's service manual specifications.

3

Step 3: If the sensor tests faulty, replace it. If the sensor is integrated into the fuel pump module, you will need to replace the entire module. Parts you'll likely need: new fuel temperature sensor (or fuel pump module).

Note: The location of the fuel temperature sensor varies significantly by vehicle. It can be a standalone sensor, integrated into the fuel rail, or most commonly, part of the fuel pump assembly inside the fuel tank.
