This summary uses the existing diagnostic information shown in full below.
This means the car's computer thinks the fuel temperature sensor is giving a reading that's too high. Imagine a thermometer showing a really high temperature even when it's not that hot.
The P0183 code indicates that the fuel temperature sensor is sending a signal to the engine control module (ECM) that is higher than the expected range.
The Fuel Temperature Sensor measures the temperature of the fuel in the fuel tank. The ECM uses this information to adjust the fuel mixture for optimal combustion. If the sensor's signal is higher than expected, it may indicate an open circuit or a faulty sensor.
• Check Engine Light is on
• Poor fuel economy
• Engine performance issues
• Faulty fuel temperature sensor
• Open or shorted wiring in the sensor circuit
• Poor electrical connection at the sensor
ECM: Engine Control Module
OBD-II: On-Board Diagnostics, Second Generation
• Use an OBD-II scanner to confirm the code.
• Visually inspect the fuel temperature sensor and its wiring.
• Test the sensor with a multimeter to check for proper resistance.
• Replace the fuel temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle to ensure the issue is resolved.
• OBD-II scanner
• Multimeter
• Wrench set
$100 - $300
Moderate
• Ford F-150
• Chevrolet Silverado
• Toyota Camry
• Regular maintenance checks on the fuel system.
• Inspect and clean electrical connections periodically.
• Use high-quality fuel to prevent sensor contamination.
Sensor Issue
• If the Check Engine Light is on, have the vehicle inspected as soon as possible.
• Avoid driving long distances until the issue is resolved.
Check with your vehicle manufacturer for specific warranty coverage on sensors.
This code has been commonly reported in vehicles with higher mileage or those exposed to extreme temperature conditions.
Moderate – It should be addressed soon to prevent further engine performance issues.
Driving with a faulty sensor can lead to increased emissions and potential engine damage.
• Engine at operating temperature
• Vehicle parked on a level surface
The fuel temperature sensor is typically located on or near the fuel rail or fuel tank.
Q: Can I drive with a P0183 code?
A: It's not recommended to drive for extended periods with this code, as it can affect engine performance and fuel economy.
Q: How do I reset the P0183 code?
A: After repairing the issue, use an OBD-II scanner to clear the code from the vehicle's computer.
