P0117 2007 Nissan Maxima Code - Engine Coolant Temperature Circuit Low

Quick Answer

The P0117 code in a 2007 Nissan Maxima indicates a problem with the engine coolant temperature circuit being lower than the normal operating range. Common causes include Faulty Coolant Temperature Sensor: A malfunctioning coolant temperature sensor can send incorrect signals to the ECM, triggering the P0117 code, Wiring or Connector Issues: Damage or corrosion in the wiring or connectors of the coolant temperature circuit can disrupt the signal to the ECM, Coolant Level: Low coolant levels or air bubbles in the cooling system can affect the accuracy of the temperature sensor. 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 2007 Nissan Maxima Description

The P0117 code in a 2007 Nissan Maxima indicates a problem with the engine coolant temperature circuit being lower than the normal operating range. This code is triggered when the Engine Control Module (ECM) detects a voltage signal from the coolant temperature sensor that is lower than expected. The coolant temperature sensor is responsible for measuring the temperature of the engine coolant and sending this information to the ECM, which uses it to adjust fuel mixture, ignition timing, and other engine functions to maintain optimal performance.

Common Causes of P0117 2007 Nissan Maxima

  1. Faulty Coolant Temperature Sensor: A malfunctioning coolant temperature sensor can send incorrect signals to the ECM, triggering the P0117 code.
  2. Wiring or Connector Issues: Damage or corrosion in the wiring or connectors of the coolant temperature circuit can disrupt the signal to the ECM.
  3. Coolant Level: Low coolant levels or air bubbles in the cooling system can affect the accuracy of the temperature sensor.
  4. ECM Malfunction: In rare cases, a faulty ECM can cause incorrect temperature readings and trigger the P0117 code.

Symptoms of P0117 2007 Nissan Maxima

  1. Check Engine Light: The most common symptom associated with the P0117 code is the illumination of the check engine light on the dashboard.
  2. Poor Fuel Efficiency: Due to incorrect engine temperature readings, the vehicle may experience decreased fuel efficiency.
  3. Rough Idling: The engine may idle roughly or inconsistently due to incorrect temperature signals.
  4. Hesitation During Acceleration: The vehicle may hesitate or have a sluggish response when accelerating.
  5. Engine Stalling: In severe cases, the engine may stall while driving or at idle.

How to Fix P0117 2007 Nissan Maxima

  1. Diagnose the Issue: Use a scan tool to retrieve the fault code and perform a visual inspection of the coolant temperature sensor, wiring, and connectors.
  2. Replace Coolant Temperature Sensor: If the sensor is faulty, replace it with a new one following manufacturer's recommendations.
  3. Check Coolant Level: Ensure the coolant level is adequate and purge any air bubbles from the cooling system.
  4. Repair Wiring or Connectors: If there are any issues with the wiring or connectors, repair or replace them as needed.
  5. Clear Fault Codes: After completing the repairs, clear the fault codes from the ECM memory and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P0117 2007 Nissan Maxima

The cost of repairing a P0117 code in a 2007 Nissan Maxima can vary depending on the specific cause of the issue. Typically, the cost of a new coolant temperature sensor ranges from $20 to $50, while the labor cost for sensor replacement can range from $50 to $150. If the issue is related to wiring or connector problems, additional diagnostic time and labor costs may be incurred. In total, the repair for a P0117 code in a 2007 Nissan Maxima can range from $100 to $300, including parts and labor. It's important to consult with a qualified mechanic or auto repair shop to get an accurate estimate based on the specific circumstances of your vehicle.

When is the Code Detected?

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