P0117 2011 Nissan Versa Code - Engine Coolant Temperature Circuit Low

Quick Answer

The P0117 code in a 2011 Nissan Versa indicates an issue with the Engine Coolant Temperature (ECT) Circuit being lower than the expected range. Common causes include Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing incorrect readings to the ECM, Wiring Issues: Damaged or corroded wiring connecting the ECT sensor to the ECM can disrupt the signal and trigger the P0117 code, ECM Malfunction: A problem with the engine control module can also result in incorrect temperature readings. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P0117 2011 Nissan Versa Description

The P0117 code in a 2011 Nissan Versa indicates an issue with the Engine Coolant Temperature (ECT) Circuit being lower than the expected range. The ECT sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module (ECM) to adjust fuel mixture and ignition timing accordingly. When the ECT circuit is reading lower than it should, it can lead to various performance issues and potentially cause long-term damage to the engine if not addressed promptly.

Common Causes of P0117 2011 Nissan Versa

  1. Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing incorrect readings to the ECM.
  2. Wiring Issues: Damaged or corroded wiring connecting the ECT sensor to the ECM can disrupt the signal and trigger the P0117 code.
  3. ECM Malfunction: A problem with the engine control module can also result in incorrect temperature readings.
  4. Coolant Leak: A coolant leak can affect the temperature readings, causing the ECT sensor to report lower temperatures.
  5. Thermostat Stuck Open: If the thermostat is stuck open, the engine may run colder than usual, triggering the P0117 code.

Symptoms of P0117 2011 Nissan Versa

  1. Illuminated Check Engine Light: The most common symptom associated with the P0117 code is the Check Engine Light coming on the dashboard.
  2. Engine Running Cold: The engine may run colder than usual, affecting performance and fuel efficiency.
  3. Poor Fuel Economy: Incorrect coolant temperature readings can lead to incorrect fuel mixture adjustments, resulting in reduced fuel efficiency.
  4. Rough Idle: The engine may experience rough idling or stalling due to improper temperature readings.
  5. Overheating: In extreme cases, the engine may overheat due to the ECT sensor providing inaccurate data to the ECM.

How to Fix P0117 2011 Nissan Versa

  1. Diagnose the Issue: Use a scan tool to read the code and check the ECT sensor's resistance and voltage. Inspect the wiring for any damage.
  2. Replace ECT Sensor: If the sensor is faulty, replace it with a new one and ensure it is properly installed.
  3. Check Wiring: Repair or replace any damaged wiring connecting the ECT sensor to the ECM.
  4. Test ECM: If necessary, test the ECM for any malfunctions and replace it if needed.
  5. Clear Codes and Test Drive: Clear the code from the ECM, start the engine, and test drive the vehicle to ensure the issue is resolved.

Cost to Fix P0117 2011 Nissan Versa

The cost of repairing the P0117 code on a 2011 Nissan Versa can vary depending on the specific cause of the issue. On average, the cost of replacing the ECT sensor and addressing any wiring issues can range from $100 to $300, including parts and labor. Additional costs may apply if the ECM needs to be replaced or if there are other underlying issues causing the code. It is recommended to consult with a professional mechanic to get an accurate estimate based on the specific circumstances of your vehicle. Additionally, labor rates at auto repair shops can vary, so it's advisable to check local rates for a more precise cost estimate.

Tech Notes for P0117 2011 Nissan Versa

If the coolant level is not low and there are no leaks, the thermostat will have to be checked/replaced. If the engine light comes back for the same issue, the Engine Coolant Temperature (ECT) sensor may need to be replaced.

When is the Code Detected?

An excessively low voltage from the sensor is sent to ECM.
