2022年7月26日 · DTC P0144 stands for “O2 Sensor Circuit High Voltage (Bank 1 Sensor 3).” This code is logged when the PCM perceives that the voltage signal in the oxygen sensor 3 located in bank 1 is too high. Code P0144 is often caused by wiring issues, a rich running condition, and a faulty oxygen sensor.

Potential causes of an P0144 code include: Start the engine and observe the Bank 1 Sensor 3 (a.k.a. 1/3) o2 sensor voltage. You may need to raise the idle up until the o2 sensor starts switching. If it is stuck high, or close to 1 volt and the voltage doesn't vary, then check for a good ground on both the heater element and the sensor.

2025年3月9日 · The P0144 trouble code is a Diagnostic Trouble Code (DTC) that indicates an issue with the oxygen sensor circuit, specifically showing high voltage readings from Bank 1 Sensor 3.

What causes a P0144 code? The P0144 code typically arises from issues within the oxygen sensor circuit. This could indicate a malfunctioning sensor, specifically Bank 1 Sensor 3. Wiring problems are common culprits as well. Damaged or frayed wires can lead to high voltage readings that trigger this code.

2020年6月14日 · Repair Information for P0144 code. Learn what O2 Sensor Circuit High Voltage Bank 1 Sensor 3 means, location and how to repair?

2025年1月1日 · The P0144 trouble code refers to an issue within the oxygen sensor circuit, specifically indicating a high voltage reading from Bank 1 Sensor 3. This sensor is crucial for monitoring the efficiency of the catalytic converter and ensuring optimal engine performance by providing feedback to the engine control module (ECM).

2017年7月26日 · P0144故障码，适用于所有汽车制造商，意思是氧传感器电路高电压（第1排，传感器 3） (O2 Sensor Circuit High Voltage (Bank 1, Sensor 3))。 提示：快速查找故障码，可以关注“ 车主指南 ”公众号，回复故障代码，如：“ P0144 ”，即可获得对应故障码解释和解决方案。

2016年7月5日 · What Does Code P0144 Mean? The internal combustion engine ignites a hydrocarbon (HC) fuel, combining it with oxygen (O2), using the resulting energy output to turn the engine. The exhaust stream, ideally, is composed simply of water (H2O), carbon dioxide (CO2), and unreacted nitrogen (N2).

Code P0144 is set when the Rear Oxygen Sensor voltage signal to the Powertrain Control Module (PCM) remains too high for an extended period of time. Resolve P0144 OBD-II code: high rear O2 sensor voltage. Identify causes like defective sensors, wiring issues. Get expert tips to fix and pass emissions.

2024年8月20日 · Fault/error code P0144 indicates the problem "Heated O2 sensor circuit High voltage (Bank 1, Sensor 3)". This code is recorded when a High voltage is detected in the heating circuit of an Oxygen (O2) sensor located in the vehicle's exhaust system.
