The Nissan Code P0180 is an error code that indicates an issue with the Fuel Tank Temperature Sensor Circuit. This code is triggered when the PCM detects a fuel tank temperature signal that is either too high or too low or when the value does not match the expected value compared to the ECT and IAT sensors. To prevent further damage, it is essential to understand the causes and solutions of this issue. The primary reasons for the P0180 code are a fuel tank temperature sensor signal that is either open or shorted to ground, a damaged or failed fuel tank temperature sensor, and a failed PCM. Below is a table of causes and potential solutions to help you troubleshoot this issue.

Fuel Tank Temperature Sensor Signal Open or Shorted to Ground
If the fuel tank temperature sensor signal is open or shorted to ground, the first step should be to check the wiring and connections of the fuel tank temperature sensor. If the wiring and connections are good, the fuel tank temperature sensor may be faulty and need replacement.
The fuel Tank Temperature Sensor is Damaged or Has Failed.
If the fuel tank temperature sensor is damaged or failed, the best solution is to replace the faulty one. This will eliminate the possibility of the issue being due to a malfunctioning sensor and ensure the fuel tank temperature sensor works properly.
PCM Has Failed
If the PCM has failed, it must be replaced to resolve the issue. The PCM is a vital vehicle component and must be in good working condition. Replacing the PCM will ensure the car functions correctly, and the Nissan Code P0180 will no longer be present.
