P0183
Fix within 1-2 weeksThe engine computer is receiving a high voltage signal from the fuel temperature sensor circuit. This indicates the sensor is reporting an abnormally low fuel temperature or there's an open circuit.
Code P0183 means the fuel temperature sensor circuit has a high voltage signal. Common causes: Faulty fuel temperature sensor (70%), wiring issues (25%). Drivability: Yes, safe to drive, but fix within 1-2 weeks. Repair cost: $50-$200 DIY, $150-$500 professional.
Can I Drive With P0183?
Yes, safe to drive
No restrictions, but address the issue to restore proper fuel economy and emissions.
Stop driving immediately if: Flashing CEL (indicates severe misfire, not typical for P0183), significant power loss, or strong fuel smell.
Symptoms of P0183
- 1Check Engine Light illuminated
- 2Hard starting, especially in cold weather
- 3Reduced fuel economy
- 4Engine running rough or stalling (less common)
- 5No noticeable symptoms (engine computer may use a default value)
Common Causes of P0183
Parts most likely causing this code, ranked by probability
The sensor itself is faulty, sending an incorrect high voltage signal to the engine computer.
70% of P0183 cases are fixed by replacing this part
Damaged, corroded, or an open circuit in the wiring or connector to the fuel temperature sensor causes an incorrect signal.
25% of P0183 cases are fixed by repairing wiring or connectors
An internal fault within the engine computer (PCM) can incorrectly interpret the sensor's signal, though this is rare.
5% of P0183 cases are fixed by replacing the PCM
Check These First (Before Buying Parts)
- Visually inspect the fuel temperature sensor's electrical connector and wiring harness for any signs of damage, corrosion, or loose connections.
- Ensure the gas cap is tight and not damaged (unlikely for P0183, but a good general check).
How to Diagnose P0183
- 1Visually inspect the fuel temperature sensor and its wiring/connector for damage, corrosion, or loose connections.
- 2Disconnect the sensor and check for proper voltage reference (usually 5V) and ground at the connector using a multimeter.
- 3Test the resistance of the fuel temperature sensor at different temperatures (if possible, or compare to specifications) using a multimeter.
- 4If wiring and sensor test good, check for continuity between the sensor connector and the PCM.
P0183 on Popular Vehicles
Ford F-150
2004-2024The fuel temperature sensor is often part of the fuel pump module inside the fuel tank. This increases labor for replacement, as the fuel tank typically needs to be dropped for access.
75% fixed by replacing the fuel pump module (which includes the sensor)
Chevrolet Silverado
2007-2024Similar to Ford, the fuel temperature sensor can be integrated into the fuel pump assembly within the fuel tank. Wiring issues are also common due to exposure under the truck.
65% fixed by replacing the fuel temperature sensor (or fuel pump module)
Toyota Camry
2007-2024The fuel temperature sensor is typically located within the fuel tank as part of the fuel pump assembly. Access usually requires removing the rear seat and accessing the top of the fuel tank.
70% fixed by replacing the fuel temperature sensor
Frequently Asked Questions
What does P0183 mean?
P0183 indicates the Powertrain Control Module (PCM) is receiving a high voltage signal from the fuel temperature sensor 'A' circuit. This suggests the sensor is reporting an abnormally low fuel temperature or there's an open circuit.
Can I drive with P0183?
Yes, you can drive safely. The engine computer will likely use a default fuel temperature value, which can lead to slightly reduced fuel economy or harder starting, but it won't cause immediate damage. Fix this within 1-2 weeks.
Will P0183 clear itself?
No, P0183 will not clear itself. The Check Engine Light will remain on until the underlying issue with the fuel temperature sensor or its circuit is diagnosed and repaired, and the code is cleared with a scan tool.
How do I fix P0183 myself?
Start by inspecting the fuel temperature sensor's wiring and connector for damage. If they look good, test the sensor's resistance with a multimeter. If the sensor is faulty, replace it.
How much does it cost to fix P0183?
A DIY repair typically costs $50-$200 for a new fuel temperature sensor. Professional repair at a shop will cost $150-$500, including parts and labor.
P0183 keeps coming back - why?
If P0183 returns, it means the initial repair didn't address the root cause. Double-check the wiring for intermittent issues, ensure the new sensor is correct and functioning, or consider a rare PCM fault.
Will P0183 fail emissions/smog test?
Yes, P0183 will cause your vehicle to fail an emissions or smog test. The illuminated Check Engine Light indicates an active fault in the emissions system, preventing the vehicle from passing.
What's the difference between P0183 and P0182?
P0183 indicates a 'high input' from the fuel temperature sensor circuit, meaning the voltage signal is too high (often an open circuit or very low temperature reading). P0182 indicates a 'low input,' meaning the voltage signal is too low (often a short circuit or very high temperature reading). Both point to an issue with the sensor or its circuit.
P0183 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 makes replacement more involved, often requiring dropping the fuel tank.
Questions to Ask Your Mechanic
Did you check the wiring and connector to the fuel temperature sensor for corrosion or damage?
Good answer: Yes, we visually inspected the harness and performed continuity tests from the sensor connector back to the PCM. Everything checked out there.

Intermediate. Requires basic electrical diagnostic skills with a multimeter and potentially accessing fuel system components, which can be messy and requires safety precautions.
Cost of Waiting
Ignoring P0183 can lead to the engine computer making incorrect fuel delivery calculations. This results in reduced fuel economy, potentially rough running, and increased emissions. While it won't cause immediate catastrophic failure, it will cost you more in fuel and prevent you from passing emissions tests.
While You're In There...
If the fuel temperature sensor is located near the fuel filter (in-line) or requires accessing the fuel tank, it's a good time to replace the fuel filter if it's due for maintenance. This prevents future fuel system issues and uses the same labor to access fuel lines/tank.
If the sensor is integrated into the fuel pump module and you're dropping the tank, consider replacing the entire module if the vehicle has high mileage or other fuel delivery symptoms. This prevents repeat labor for a common wear item.
Tools You'll Need
- OBD-II scan tool
- Multimeter
- Basic hand tools (wrenches, sockets, screwdrivers)
- Wire strippers/crimpers (if repairing wiring)
- Fuel line disconnect tool (if sensor is in-line)
- Jack and jack stands (if accessing under vehicle or dropping tank)
P0183 is a common sensor code. Most repairs involve replacing an inexpensive sensor or fixing a simple wiring issue, restoring your vehicle's proper fuel system function.

Your Next Steps
Step 1: Inspect Wiring and Connector. Carefully examine the wiring harness leading to the fuel temperature sensor for any cuts, fraying, or signs of rodent damage. Check the connector for corrosion or bent pins. Clean any corrosion and ensure a tight connection.
Step 2: Test Sensor and Circuit. If the wiring looks good, use a multimeter to test the fuel temperature sensor's resistance and check for proper voltage reference (typically 5V) at the connector. Compare readings to your vehicle's service manual specifications.
Step 3: Replace Faulty Components. If the sensor tests faulty, replace the fuel temperature sensor. If the wiring is damaged, repair it. If the sensor is integrated into the fuel pump module, you may need to replace the entire module.
