What is P0183 fault code? What is the description of Fuel Temperature Sensor “A” Circuit High Input malfunction? How do I fix the P0183 fault code What are the causes and symptoms of the P0183 error code?
What is the P0183 fault code? What does it signify?
Temperature is the main factor that determines the fuel’s density. The fuel is denser the colder it is. The powertrain control module, or PCM, monitors the fuel density to determine how much fuel is injected into cylinders. It also controls the fuel temperature. The PCM uses fuel temperature sensor values to optimize engine performance and efficiently burn fuel. The fuel temperature sensor produces a high voltage signal when it is cold. It decreases as the fuel heats up. The PCM will set malfunction code P0183 if it detects that the fuel temperature sensor voltage signal is too high.
The PCM adjusts the air-fuel ratio by using the fuel temperature sensor. It can adjust the engine speed by adjusting the amount of fuel needed. This also reduces emissions by reducing the amount unburned fuel that comes out of the engine.
The PCM periodically checks the signal coming from the fuel temperature sensor. It then compares it to the parameters in its memory. The P0183 malfunction codes will be activated if the PCM detects a voltage signal from the fuel temp sensor “A”, exceeding the predetermined parameters. The code’s description states that “A” refers to a particular circuit and not any component.
P0183 fault codes can be found on vehicles made by Ford, Hyundai and Volkswagen.
What is the P0183 Fault Code and Why Does It Happen?
These are the most common reasons that P0183 fault codes are triggered:
- – Defective fuel temperature sensor
- – Broken wires, loose connectors or rusty connections, open or short circuit problems
- – Defective PCM
What are the symptoms for P0183 fault code?
You may experience the following symptoms if your vehicle has a P0183 code:
- – Illumination at the check engine lights
- – Engine hard start
- – Low engine performance (misfires, stalling and hesitation during acceleration etc.
- – Increased fuel consumption
How do I fix the P0183 fault code?
The following repairs may be able to resolve the P0183 fault code:
- – Replacing the defective fuel temperature sensor
- – Replacing a bad fuel composition sensor (in some cars both sensors are integrated).
- – Repair of damaged wiring, loose connectors or rusty connections, and open or short circuit problems
- – Replacing the defective PCM
