Error Code P0183: What It Means & What To Do?

<<See All OBD Codes

The P0183 fault code can be defined as fuel temperature sensor A circuit high input. It is a generic code which would indicate that the fuel temperature sensor A circuit voltage has gone above calibrated limit specifications during the self test.

The fuel tank temperature sensor is generally used to detect the fuel temperature inside the fuel tank. A voltage signal would be modified by the sensor from the engine control module. The modified signal would then return to the engine control module as the fuel temperature input. A thermistor can be used by a sensor which is sensitive to the change in the temperature. The electrical resistance of the thermistor would decrease with an increase in the temperature.

What causes this problem with the Fuel Temperature Sensor A Circuit High Input?

• Defaults in the intake air temperature sensor
• Poor ambient temperature sensor
• Some faults in the fuel temperature/composition sensor
• Problem of open, shorted, or damaged wiring or connectors
• There can be a programming error in the powertrain control module

1. Fuel Temperature Sensor - Defective car Fuel Temperature Sensor can be a major reason why P0183 code depicts. So, make sure to replace it online so that you don’t have to face any further issues.
2. Oil Pressure sensor - Everything is okay with the timing chain and still OBD code P0183 triggering? Then there must be some defects in crankshaft sensors. Replace them as soon as possible.
3. Powertrain Control Module - Powertrain Control Module is an important auto part. Take care of it and you can rely on us to purchase best quality Powertrain Control Module online.
4. Diagnostic Tools - Willing to purchase some top-notch diagnostic tools online? We are here at your service.

It is very important to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0183 here:

Common Symptoms

• If you find out that the car fuel is extremely cold, the vehicle won’t be able to start due to fuel volatility
• Excessive additives in the fuel can cause erratic engine operation or stalling and hesitations
• The engine control module would set code P0183 to memory and would illuminate the check engine light

• Have a look at some ways with which you can correct the P0183 code:
• If the fuel temperature sensor tests are out of specifications, then it should be replaced
• You must repair or replace the defective connector or wiring to the sensor
• A faulty engine control module should be replaced

Make sure that you replace the diesel fuel heater assembly with the temperature sensor

There is no need to get strained if your OBD Code is still flashing up as we are here at your service. Have a look at our superior variety of coolant temperature sensor, fuel tank pressure sensor, fuel sensor and many more. Now all your problems would vanish within no time.

You must use digital volt-ohm meter and an electrical wiring diagram and repair manual to diagnose faults in the FTS circuit and FTS.

The FTS is situated in the fuel tank, as part of the fuel sending unit, or practically anywhere else, before the fuel injectors, in the fuel system. You can always check your manual for the precise location of the FTS.

It would depend on the location of the ECM and FTS you may have to work to get at their connectors, such as if located in the fuel tank under the seat. One can start this diagnosis from the ECM or from the FTS, it would all depend on what can be easily accessed.

• The first thing which you should do is to scan the codes and documents the freeze frame data, after that the codes should be cleared to verify if the code returns
• Perform a visual check of all the wiring and connections to the sensor, checking for breaks in the wiring or loose connections
• After that you should disconnect the connection to the sensor and check to see if the sensor is testing within specifications
• Then take a fuel sample to compare the fuel temperature to the sensor input
• The diesel fuel heater should the tested for proper operation to make sure it is working to heat the fuel without overheating the fuel

Common Mistakes When Diagnosing The P0183 Code

• All the connections should be visually inspected to the sensor to make sure that the harness is not shorted, and that the connector is not fuel contaminated, which causes shorts
• You must check the fuel for excessive additives that can cause sensors to malfunction
