Guide To P0182 OBD Error Code Solutions

<<See All OBD Codes

The P0182 can be defined as fuel temperature sensor ‘A’ circuit low input. It is a generic code which would indicate that the fuel temperature sensor ‘A’ circuit voltage fell below calibrated limit specifications during the self-test

The powertrain control module might detect an abnormal voltage reading from the fuel temperature sensor or the circuit. This sensor is designed in such a way it can detect fuel contamination and would provide the powertrain control module with an accurate fuel temperature.

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

• The ambient temperature sensor might be bad
• Some faults in the fuel temperature/composition sensor
• The intake air temperature sensor might be defective
• The issue of open, shorted, or damaged wiring or connectors
• The powertrain control module programming error

1. Fuel Temperature Sensor - The P0182 code can also arise due to some issues in Fuel Temperature Sensor. So, it is advised to replace them as soon as possible.
2. Oil Pressure sensor - P0182 code does not really end up spoiling your Fuel Temperature Sensor, but it might also accompany few Oil Pressure sensor issues. We have best powertrain related parts with us.
3. Powertrain Control Module - A broken Powertrain Control Module can cause a lot of issues. It would be nice if you get it replaced on time.
4. Diagnostic Tools - Willing to purchase some top-notch diagnostic tools online? We are here at your service.

You might be thinking that how would you diagnose these problems? We at Parts Avatar Canada would help you diagnose the major symptoms easily.

Common Symptoms

• Your car won’t start, or it may lose power and can start stalling if the fuel gets too hot and boils off
• Excessive additives in the fuel could cause the fuel to boil off at lower temperatures, resulting in erratic sensor readings
• The P0182 fault code would be set by the engine control module and check engine light would start appearing

It is very important to fix the fault code P0182. So here are some ways with which you can correct this issue:

• First of all you must test the fuel temperature sensor and replacing it if it is out of specifications
• You must repair or replace a defective connector or wiring to the sensor
• If there are some faults in the engine control module, it should be replaced
• Repairing an exhaust leak onto the fuel line
• The diesel fuel heater assembly should be replaced with the temperature sensor

Don’t get tensed if you are still facing any of these issues as we care for our customers and that’s why we offer a good range of coolant temperature sensor, fuel tank pressure sensor, fuel sensor and a lot more. We are sure that now all your issues would be resolved.

If you willing 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.

• Make sure that you scan the codes and documents the freeze frame data, after that the codes should be cleared to verify if the code returns
• You can always do 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
• 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 P0182 Code

• You must visually inspect the connections to the sensor to make sure that the harness is not shorted, and that the connector is not fuel contaminated, which causes shorts
• Make sure that you check the fuel for excessive additives that can cause sensors to malfunction
• If the vehicle has an exhaust leakage, then you should check to make sure that it is not heating up the fuel lines
