Why do you need a fuel temperature sensor?
On engines equipped with a fuel temperature sensor (FTS), this results in finer control of air-fuel ratio and lower emissions. Earlier vehicles not equipped with an FTS achieved similar results using feedback from the AFR sensors. The ECM continually monitors the resistance of the FTS, calculating temperature based on those readings.
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?
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.
Where is the FTS located in the fuel tank?
The FTS may be located in the fuel tank, as part of the fuel sending unit, or practically anywhere else, before the fuel injectors, in the fuel system. Check your manual for the precise location of the FTS.
Where is the fuel temperature sensor located?
The Fuel Temperature Sensor is located on the fuel rail under the upper intake manifold shield. It will have a two wire connector going to it.
What is the fastest temperature sensor?
The fastest-possible temperature sensor is an exposed tip thermocouple. However, manufacturing improvements have also greatly improved the response times of thin-film PT100 probes. Accuracy: RTDs are generally more accurate than thermocouples.
What are the symptoms of a bad coolant temperature sensor?
Another symptom of a problem with the coolant temperature sensor is an overheating engine. The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
Can the coolant temperature sensor affect the fuel consumption?
Yes engine coolant temp can effect fuel consumption because the PCM (computer ) uses it to determine when to place the system into closed loop operation (warmed up engine) . In most cases its not the coolant temp sensor that fails on the ranger but instead the thermostat which confuses the sensor signal and cause the PCM to richen the mixture and keep it in open loop longer on cold starts.
