P0117 2006 Nissan Pathfinder Code - Engine Coolant Temperature Circuit Low

Quick Answer

The P0117 diagnostic trouble code (DTC) for a 2006 Nissan Pathfinder refers to the Engine Coolant Temperature Circuit Low. Common causes include Faulty Engine Coolant Temperature Sensor: The sensor may be malfunctioning, providing incorrect temperature readings to the ECM, Damaged Wiring or Connectors: Wiring or connectors in the coolant temperature circuit may be damaged, leading to a low signal, ECM Malfunction: The ECM itself may be faulty, causing it to misinterpret the temperature sensor data. 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 2006 Nissan Pathfinder Description

The P0117 diagnostic trouble code (DTC) for a 2006 Nissan Pathfinder refers to the Engine Coolant Temperature Circuit Low. This code is triggered when the Engine Control Module (ECM) detects that the engine coolant temperature sensor signal is lower than the normal operating range. The engine coolant temperature sensor is a crucial component that monitors the temperature of the engine coolant and provides this information to the ECM. The ECM uses this data to adjust fuel delivery and ignition timing for optimal engine performance and efficiency.

Common Causes of P0117 2006 Nissan Pathfinder

  1. Faulty Engine Coolant Temperature Sensor: The sensor may be malfunctioning, providing incorrect temperature readings to the ECM.
  2. Damaged Wiring or Connectors: Wiring or connectors in the coolant temperature circuit may be damaged, leading to a low signal.
  3. ECM Malfunction: The ECM itself may be faulty, causing it to misinterpret the temperature sensor data.
  4. Low Coolant Level: A low coolant level can also trigger the P0117 code, as the sensor may not be submerged in coolant to provide accurate readings.
  5. Coolant Temperature Sensor Circuit Short: A short circuit in the coolant temperature sensor circuit can cause the sensor to read lower temperatures than actual.

Symptoms of P0117 2006 Nissan Pathfinder

  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: A malfunctioning engine coolant temperature sensor can lead to incorrect fuel delivery, resulting in decreased fuel efficiency.
  3. Rough Idling: The engine may experience rough idling or stalling due to incorrect temperature readings.
  4. Difficulty Starting: The vehicle may have difficulty starting or take longer to start than usual.
  5. Overheating: In severe cases, ignoring this issue can lead to engine overheating, which may result in engine damage.

How to Fix P0117 2006 Nissan Pathfinder

  1. Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a thorough inspection of the engine coolant temperature sensor, wiring, and connectors.
  2. Replace Engine Coolant Temperature Sensor: If the sensor is faulty, replace it with a new one and ensure it is properly installed.
  3. Repair Damaged Wiring or Connectors: If wiring or connectors are damaged, repair or replace them as needed to restore proper functionality.
  4. Reset the ECM: Clear the DTC and reset the ECM to ensure the issue is resolved and the check engine light is turned off.
  5. Test Drive: After completing the repair, test drive the vehicle to ensure that the issue has been resolved and that the engine is running smoothly.

Cost to Fix P0117 2006 Nissan Pathfinder

The typical repair costs for addressing the P0117 code on a 2006 Nissan Pathfinder can range from $100 to $300, depending on the specific cause of the issue and the cost of parts and labor. This estimate includes the cost of a new engine coolant temperature sensor, any necessary wiring repairs, and labor charges. It is important to note that the actual cost may vary based on the location of the repair shop, the vehicle's make and model, and the extent of the repairs needed. Additionally, diagnosis time and labor rates can vary, with most auto repair shops charging between $80 and $150 per hour. It is recommended to obtain a detailed quote from a trusted mechanic to determine the exact cost of addressing the P0117 code on a 2006 Nissan Pathfinder.
