Fixes: Repair or replace the faulty oxygen sensor, repair damaged wiring, replace the blown fuse, or replace the PCM to fix P0144 code in Nissan.
P0144 Code Nissan:
The P0144 code in a Nissan vehicle indicates a problem with the heated oxygen sensor 3 (HO2S3) heater control circuit. This sensor is responsible for monitoring the oxygen levels in the exhaust system and sending that information to the engine control module (ECM). The ECM uses this data to adjust the air/fuel mixture to ensure optimal engine performance and reduce emissions. When the HO2S3 heater control circuit is detected to be low, it means that there is a problem with the sensor’s ability to heat up quickly enough to provide accurate readings. This can lead to decreased fuel efficiency, increased emissions, and potential damage to the engine over time.
To fix this issue, the first step is to check the wiring and connections to the HO2S3 sensor. If there are any damaged or corroded wires or loose connections, they should be repaired or replaced. If the wiring and connections are in good condition, the sensor itself may need to be replaced. It’s important to address this issue as soon as possible to prevent further damage to the engine and ensure optimal performance and fuel efficiency.

Signs and Symptoms of P0144 Code in Nissan Vehicles
The P0144 code in Nissan vehicles indicates a problem with the heated oxygen sensor 3 (HO2S3) heater control circuit. This sensor is responsible for monitoring the oxygen levels in the exhaust system and providing feedback to the engine control module (ECM) to adjust the air/fuel ratio for optimal performance and fuel efficiency. When the HO2S3 heater control circuit is malfunctioning, it can cause a variety of symptoms that can affect the performance and drivability of the vehicle.
Here are some of the signs and symptoms of the P0144 code in Nissan vehicles:
- Check Engine Light: The most common symptom of the P0144 code is the illumination of the check engine light on the dashboard. This light is triggered by the ECM when it detects a problem with the HO2S3 heater control circuit.
- Poor Fuel Economy: A malfunctioning HO2S3 sensor can cause the engine to run rich or lean, which can result in poor fuel economy. This can be especially noticeable during highway driving or when accelerating.
- Engine Misfires: If the HO2S3 sensor is not providing accurate feedback to the ECM, it can cause the engine to misfire or run rough. This can be felt as a hesitation or stuttering when accelerating or cruising at a steady speed.
- Reduced Power: A malfunctioning HO2S3 sensor can also cause the engine to lose power or feel sluggish. This can be especially noticeable when climbing hills or towing a heavy load.
- Failed Emissions Test: If the HO2S3 sensor is not functioning properly, it can cause the vehicle to fail an emissions test. This is because the sensor is responsible for monitoring the oxygen levels in the exhaust system, which is a key component of emissions control.
If you are experiencing any of these symptoms in your Nissan vehicle, it is important to have it diagnosed and repaired as soon as possible. Ignoring the P0144 code can lead to further damage to the engine and other components, and can result in costly repairs down the line. A qualified mechanic can use diagnostic tools to pinpoint the exact cause of the problem and recommend the appropriate
P0144 Code Nissan:
The P0144 code in Nissan vehicles indicates a problem with the heated oxygen sensor 3 (HO2S3) heater control circuit. This sensor is responsible for monitoring the oxygen levels in the exhaust system and providing feedback to the engine control module (ECM) to adjust the air-fuel ratio for optimal performance and fuel efficiency.
There are several possible causes of the P0144 code, including:
- Failed HO2S3: The most common cause of the P0144 code is a failed HO2S3. This can be due to normal wear and tear or damage from exposure to high temperatures or contaminants in the exhaust system.
- Wiring issues: The wiring that connects the HO2S3 to the ECM can become damaged or corroded over time, leading to a loss of signal or a short circuit.
- Failed ECM: In rare cases, the ECM itself may be faulty and unable to properly control the HO2S3 heater circuit.
- Blown fuse: A blown fuse in the HO2S3 heater circuit can prevent the sensor from receiving power and cause the P0144 code to appear.
If left unaddressed, the P0144 code can lead to decreased fuel efficiency, reduced engine performance, and increased emissions. To fix the issue, a mechanic will need to diagnose the underlying cause of the code and make any necessary repairs. This may involve replacing the HO2S3 sensor, repairing or replacing damaged wiring, replacing a blown fuse, or replacing the ECM if it is found to be faulty.
It is important to note that attempting to diagnose and repair the P0144 code without the proper tools and experience can be dangerous and may cause further damage to the vehicle. It is recommended to seek the assistance of a qualified mechanic to properly diagnose and repair the issue.
Fixes for P0144 Code in Nissan Vehicles
The P0144 code in Nissan vehicles indicates a problem with the heated oxygen sensor 3 heater control circuit. This code is usually triggered when the voltage in the circuit is lower than the expected range. Here are some of the fixes for this code:
- Replace the oxygen sensor: The most common fix for the P0144 code is to replace the oxygen sensor. This is because the sensor may have failed or become damaged, causing the voltage in the circuit to drop. A new sensor should be installed to restore proper function.
