P0184 OBD Error Code: Problem & Solutions
OBD Code P0184 - Fuel Temperature Sensor A Circuit Intermittent
The P0184 can be defined as fuel temperature
sensor ‘A’ circuit intermittent. The fuel temperature sensor would tell the
engine control module the temperature of the fuel. If the powertrain control
module would detect an implausible signal from the fuel temperature sensor,
then the P0184 code would be set by the powertrain control module.

It is the fuel tank temperature sensor which is
used to detect the fuel temperature inside the fuel tank. The sensor would then
modify the voltage signal from the engine control module. This modified signal
would then return to the engine control module as the fuel temperature input. A
thermistor is used by a sensor which is sensitive to the change in the
temperature. The electrical resistance of the thermistor would decrease as the
temperature increases.
What causes this problem with the Fuel Temperature Sensor A Circuit
Intermittent?
- The issue of open, shorted, or
damaged wiring or connectors
- Faulty fuel temperature/composition
sensor
- Some defaults in the intake air
temperature sensor
- There can be poor ambient temperature sensor
- The powertrain control module programming error
Replace/Repair These Parts To Fix OBD Code P0184

Symptoms Of OBD Error Code P0184
We care for our customers and that’s
why we can totally understand your problem. That’s the reason why we have
listed out some major symptoms behind the flashing up of OBD Code P0184. They
are mentioned here as follows:
Common Symptoms
- If the sensor is intermittent then
the engine will not be able to run normally, unless the fuel is contaminated
- A lot of additives in the fuel which can cause erratic sensor readings and cause the fuel to boil off at lower temperatures or freeze too early
- The P0184 fault code would start triggering by the engine control module and there would be an illumination in the check engine light
How To Correct P0184 Fuel Temperature Sensor A Circuit Intermittent
We have listed out some ways which
would help you to correct the occurrence of OBD Code P0184. They are mentioned
here as follows:
- First of all you must inspect the
fuel temperature sensor and you can always replace it if it is out of
specifications
- A defective connector or wiring to
the sensor should be repaired or replaced
- You should the diesel fuel heater
assembly with the temperature sensor

Easy Diagnosis Of Engine Error OBD Code P0184
Do you want to diagnose the faults in the FTS circuit and FTS? Then you must use digital volt-ohm meter and an electrical wiring diagram and repair manual. 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.
- Carefully scan the codes and
documents the freeze frame data, after that the codes should be cleared to
verify if the code returns
- It would be very helpful to perform
a visual check of all the wiring and connections to the sensor, checking for
breaks in the wiring or loose connections
- The connection to the sensor should
be disconnected and check to see if the sensor is testing within specifications
- After that you should take a fuel
sample to compare the fuel temperature to the sensor input
- Make sure that you test the diesel
fuel heater for proper operation to be sure it is working to heat the fuel
without overheating the fuel
Common Mistakes When Diagnosing The P0184 Code
- Make sure that you perform a visual check of connections to the sensor to make sure they are making good contact to the fuel temperature sensor.
- Inspect the fuel for excessive additives that can be a reason why sensors are becoming erratic
