Code P1052 2004 Infiniti G35 Description
The P1052 code on a 2004 Infiniti G35 indicates a problem with the Air Fuel Ratio Sensor 1 Heater Control Circuit on Bank 2. This sensor is responsible for monitoring the air-fuel mixture in the exhaust system and sending data to the engine control module (ECM) for optimal fuel efficiency and emissions control. The heater control circuit is designed to keep the sensor at a specific temperature for accurate readings. When the circuit is detected to be operating at a high voltage, it means that the sensor's heating element is not functioning properly, which can lead to inaccurate readings and affect the vehicle's performance.
Common Causes of P1052 2004 Infiniti G35
- Faulty Air Fuel Ratio Sensor: The sensor itself may be defective and require replacement.
- Wiring Issues: Damage or corrosion in the wiring harness connected to the sensor can disrupt the heater control circuit.
- ECM Malfunction: A problem with the engine control module can also trigger this code.
- Exhaust System Leak: A leak in the exhaust system can affect the sensor's readings and trigger the code.
- Sensor Contamination: Contaminants such as oil or coolant can interfere with the sensor's operation.
Symptoms of P1052 2004 Infiniti G35
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
