Code P0117 2012 Nissan Altima Sedan Description
The P0117 code in a 2012 Nissan Altima Sedan indicates a problem with the Engine Coolant Temperature (ECT) Circuit being lower than the expected voltage range. The ECT sensor is responsible for monitoring the temperature of the engine coolant, which is crucial for the proper functioning of the engine. When the ECT sensor detects a lower voltage than expected, it can lead to various issues with the vehicle's performance.
Common Causes of P0117 2012 Nissan Altima Sedan
- Faulty ECT Sensor: The most common cause of this code is a malfunctioning ECT sensor that is not providing accurate temperature readings.
- Wiring Issues: Problems with the wiring in the ECT circuit, such as shorts or open circuits, can also trigger this code.
- Thermostat Malfunction: A faulty thermostat can cause the engine to run too cold, leading to incorrect temperature readings from the ECT sensor.
- Low Coolant Levels: Insufficient coolant in the engine can affect the temperature readings from the ECT sensor, triggering the code.
- Engine Coolant Leaks: Leaks in the coolant system can also impact the ECT sensor's readings and lead to the P0117 code.
Symptoms of P0117 2012 Nissan Altima Sedan
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Poor Fuel Economy: A malfunctioning ECT sensor can cause the engine to run too cold, leading to decreased fuel efficiency.
- Engine Running Rough: The engine may run rough or misfire due to incorrect temperature readings from the ECT sensor.
- Difficulty Starting: In some cases, a faulty ECT sensor can cause difficulty starting the engine, especially in cold weather.
- Overheating: If the ECT sensor is providing incorrect readings, it can lead to engine overheating, which may result in steam coming from the engine or a rise in the engine temperature gauge.
How to Fix P0117 2012 Nissan Altima Sedan
- Diagnose the Issue: Use a scan tool to read the code and check the ECT sensor's voltage readings to determine the root cause of the problem.
- Replace ECT Sensor: If the ECT sensor is found to be faulty, replace it with a new one to ensure accurate temperature readings.
- Check Wiring: Inspect the wiring in the ECT circuit for any damage or corrosion and repair or replace as necessary.
- Test Thermostat: Verify the operation of the thermostat to ensure it is functioning correctly and replace if needed.
- Check Coolant Levels: Verify the coolant levels in the engine and address any leaks or top up coolant as required.
Cost to Fix P0117 2012 Nissan Altima Sedan
The cost of repairing the P0117 code on a 2012 Nissan Altima Sedan can vary depending on the specific cause of the issue. In general, the cost for parts such as a new ECT sensor can range from $50 to $100, while labor costs can range from $80 to $150 per hour. Overall, the total repair cost for this issue could range from $150 to $300, but it is advisable to check with local auto repair shops for a more accurate estimate based on your location and vehicle specifics.
