P0117 2006 Infiniti G35 Code - Engine Coolant Temperature Circuit Low
Quick Answer
The P0117 code for a 2006 Infiniti G35 indicates a problem with the Engine Coolant Temperature (ECT) Circuit being too low. Common causes include Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM, Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the ECT circuit can disrupt the signal to the ECM, Low Coolant Level: Insufficient coolant in the system can affect the ECT sensor's readings and trigger the P0117 code. 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 Infiniti G35 Description
The P0117 code for a 2006 Infiniti G35 indicates a problem with the Engine Coolant Temperature (ECT) Circuit being too low. The Engine Coolant Temperature Sensor (ECT sensor) is a crucial component that monitors the temperature of the engine coolant. This information is used by the engine control module (ECM) to adjust fuel delivery and ignition timing, ensuring optimal engine performance and efficiency. When the ECT sensor detects a low voltage signal, it triggers the P0117 code, indicating a potential issue with the ECT circuit.
Common Causes of P0117 2006 Infiniti G35
- Faulty ECT Sensor: The ECT sensor itself may be malfunctioning, providing incorrect temperature readings to the ECM.
- Damaged Wiring or Connectors: Corrosion, fraying, or damage to the wiring or connectors in the ECT circuit can disrupt the signal to the ECM.
- Low Coolant Level: Insufficient coolant in the system can affect the ECT sensor's readings and trigger the P0117 code.
- ECM Malfunction: A rare but possible cause is a malfunctioning ECM that is unable to interpret the signals from the ECT sensor correctly.
- Cooling System Issues: Problems with the cooling system, such as a faulty thermostat or water pump, can impact the ECT sensor's readings.
Symptoms of P0117 2006 Infiniti G35
- Check Engine Light: The most common symptom associated with the P0117 code is the illumination of the Check Engine Light on the dashboard.
- Poor Fuel Economy: A faulty ECT sensor can lead to incorrect fuel adjustments, resulting in decreased fuel efficiency.
- Engine Overheating: If the ECT sensor provides inaccurate temperature readings, the engine may overheat due to improper cooling system operation.
- Rough Idling: Incorrect fuel and ignition timing adjustments can cause the engine to idle roughly or stall.
- Hard Starting: A malfunctioning ECT sensor may lead to difficulty starting the engine, especially in cold weather.
How to Fix P0117 2006 Infiniti G35
- Diagnose the Issue: Use a diagnostic scanner to retrieve the trouble codes and perform a thorough inspection of the ECT sensor, wiring, connectors, and cooling system components.
- Replace ECT Sensor: If the ECT sensor is faulty, replace it with a new sensor compatible with the Infiniti G35 model.
- Repair Wiring or Connectors: Repair or replace any damaged wiring or connectors in the ECT circuit to ensure a proper connection.
- Check Coolant Level: Verify that the coolant level is adequate and top up if necessary to ensure accurate temperature readings.
- Clear Codes and Test Drive: Clear the trouble codes from the ECM, start the vehicle, and test drive to ensure the issue has been resolved.
Cost to Fix P0117 2006 Infiniti G35
The typical repair costs for addressing a P0117 code on a 2006 Infiniti G35 can range from $100 to $300, including parts and labor. The cost may vary depending on the specific cause of the issue, the price of the ECT sensor, and the labor rates at the auto repair shop. It's important to note that diagnosis time and labor rates can vary based on factors such as location, vehicle make and model, and engine type. Auto repair shops commonly charge between $80 and $150 per hour, with rates potentially higher in metropolitan areas or at dealerships and lower at independent shops. To obtain a more precise estimate, it's recommended to inquire about local rates before proceeding with the repair.
