P0117 Code Nissan:
The P0117 code in a Nissan vehicle indicates a problem with the engine coolant temperature circuit. This code is triggered when the engine control module (ECM) detects that the engine coolant temperature sensor is sending a signal that is lower than the expected range. This can be caused by a faulty sensor, a wiring issue, or a problem with the ECM itself. When this code is present, the vehicle may experience poor fuel economy, rough idling, or even stalling. To fix this issue, the first step is to diagnose the problem by checking the sensor and wiring for any damage or corrosion. If these components are in good condition, the ECM may need to be replaced.
What are the Signs or Symptoms of P0117 Code in Nissan?
The P0117 code in Nissan indicates a problem with the engine coolant temperature circuit. This code is triggered when the engine control module (ECM) detects that the engine coolant temperature sensor is sending a signal that is lower than the expected range. Here are some of the signs and symptoms that you may experience if your Nissan is showing the P0117 code:
- Check Engine Light: The most common symptom of the P0117 code is the illumination of the check engine light on the dashboard. This light indicates that there is a problem with the engine that needs to be addressed.
- Engine Performance Issues: If the engine coolant temperature sensor is sending a signal that is lower than the expected range, it can cause a variety of engine performance issues. You may notice that your Nissan is running rough, stalling, or hesitating when you accelerate.
- Poor Fuel Economy: A faulty engine coolant temperature sensor can also cause your Nissan to consume more fuel than usual. This is because the ECM may be sending more fuel to the engine than it needs, based on the incorrect temperature reading.
- Overheating: In some cases, a faulty engine coolant temperature sensor can cause your Nissan to overheat. This is because the ECM may not be able to accurately monitor the engine temperature, which can lead to overheating and potential engine damage.
- Difficulty Starting: If the engine coolant temperature sensor is sending a signal that is too low, it can cause difficulty starting your Nissan. This is because the ECM may not be able to accurately determine the correct fuel-to-air ratio needed for starting the engine.
If you are experiencing any of these symptoms, it is important to have your Nissan diagnosed by a qualified mechanic as soon as possible. Ignoring the P0117 code can lead to further engine damage and potentially costly repairs.This response was truncated by the cut-off limit (max tokens).

P0117 Code Nissan:
The P0117 code is a diagnostic trouble code (DTC) that indicates a problem with the engine coolant temperature (ECT) sensor circuit. This code is specific to Nissan vehicles and can be found on models such as the Altima, Maxima, Sentra, and Pathfinder. The ECT sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM). If the ECM detects a low voltage signal from the ECT sensor, it will trigger the P0117 code.
There are several possible causes of the P0117 code, including:
- Failed ECT sensor: The most common cause of the P0117 code is a failed ECT sensor. Over time, the sensor can become damaged or worn out, which can cause it to send incorrect signals to the ECM.
- Wiring issues: Another possible cause of the P0117 code is wiring issues. If the wiring that connects the ECT sensor to the ECM is damaged or corroded, it can cause a low voltage signal to be sent to the ECM.
- Failed ECM: In rare cases, a failed ECM can cause the P0117 code to appear. If the ECM is not receiving the correct signal from the ECT sensor, it may trigger the code even if the sensor is functioning properly.
- Low coolant level: If the engine coolant level is low, it can cause the ECT sensor to send a low voltage signal to the ECM. This can trigger the P0117 code even if the sensor is functioning properly.
- Failed thermostat: A failed thermostat can also cause the P0117 code to appear. If the thermostat is stuck open, it can cause the engine coolant to circulate too quickly, which can result in a low voltage signal being sent to the ECM.
If you are experiencing the P0117 code, it is important to have your vehicle diagnosed by a qualified mechanic. They will be able to determine the exact cause of the code and recommend the appropriate repairs. In most cases, the ECT sensor will need to be replaced.

Fixes for P0117 Code Nissan
The P0117 code in Nissan vehicles indicates a problem with the engine coolant temperature circuit. This code is triggered when the engine control module (ECM) detects that the engine coolant temperature sensor is reporting a low voltage signal. This can be caused by a variety of issues, including a faulty sensor, damaged wiring, or a malfunctioning ECM. Here are some of the fixes for the P0117 code:
1. Check the engine coolant temperature sensor: The first step in fixing the P0117 code is to check the engine coolant temperature sensor. This sensor is located on the engine block and measures the temperature of the coolant. If the sensor is faulty, it will need to be replaced.
2. Inspect the wiring: If the engine coolant temperature sensor is working properly, the next step is to inspect the wiring. Look for any signs of damage or corrosion, and repair or replace any damaged wires as needed.
3. Check the ECM: If the engine coolant temperature sensor and wiring are both in good condition, the problem may be with the ECM. The ECM is responsible for receiving signals from the sensor and controlling the engine’s performance. If the ECM is malfunctioning, it may need to be replaced.
4. Replace the thermostat: In some cases, a faulty thermostat can cause the engine coolant temperature to be too low, triggering the P0117 code. If the thermostat is stuck open, it will need to be replaced.
5. Check the coolant level: Low coolant levels can also cause the engine coolant temperature to be too low. Check the coolant level and add more if necessary.
6. Repair or replace the radiator: A damaged or clogged radiator can also cause the engine coolant temperature to be too low. If the radiator is damaged or clogged, it will need to be repaired or replaced.
7. Check the water pump: The water pump is responsible for circulating the coolant through the engine. If the water pump is not working properly, it can cause the engine coolant temperature to be too low. Check the water pump and replace it if necessary.
