What is the trouble code for a fuel temperature sensor?
P0183 – Fuel temperature sensor A -high input Trouble Code Fault Location Probable Cause P0183 Fuel temperature sensor A -high input Wiring short to positive, fuel temperatu
What does the p0183 code on a fuel temperature sensor mean?
What the P0183 code means. P0183 is a generic OBD-II code indicating that the fuel temperature sensor A circuit voltage went above calibrated limit specifications during the self test.
Do you need a manual fuel pressure tester?
A manual fuel pressure tester is needed to diagnose P0087. This allows us to check fuel pressure at the fuel rail and then use the scan tool to check what the fuel pressure sensor is reading. Both of these readings are needed to test the fuel pressure sensor.
What causes a fuel sensor to go out of range?
The fuel tank or fuel rail temperature sensor is going out of range, due to the connector being contaminated, causing an intermittent open in the circuit connection If the fuel goes below the temperature sensor’s range due to a fault, or the ambient temperature goes below -40 degrees F What are the symptoms of the P0183 code?
Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
What does p0183 mean on the fuel temp sensor?
When P0183 is set, the PCM has determined that the input voltage from fuel temp sensor A is higher than the calibrated limit indicating a lower than normal temperature.
How does the fuel temperature sensor work on a flex fuel vehicle?
Flex fuel vehicles function normally even if fuel composition levels are as high as eighty-five-percent ethanol. Fuel temperature is recognized by the PCM as pulse width or the horizontal portion of the waveform. The thicker the pulse width signal, the higher the temperature of the fuel passing through the fuel composition sensor.
What does the coolant temperature sensor tell you?
The ECT sensor, also commonly just called the coolant temperature sensor, measures how hot the engine in your car is. Fuel delivery, ignition timing and engine performance are among the key elements affected by the information the coolant temperature sensor gathers.

What does the code p0174 mean on a V engine?
Code P0174 applies to V engines as they will have two banks, Bank 1 and Bank 2. When the code says that the Fuel System is “too lean,” it means that the computer has been adding more and more fuel, which is called Long Term Fuel Trim. Ideally, the Long Term Fuel Trim should be close to 1 to 2 percent.
When to suspect a fault in the FTS?
If you see 5 V reference, but no signal voltage, suspect a fault in the FTS. Replace as necessary. If you see 5 V on the signal line, suspect an open-circuit in the signal line to the ECM, short-circuit to the reference line from the ECM, or a short-to-ground in the signal line before the ECM. Repair as necessary.
