This P2272 trouble code refers to the post-catalytic converter O2 (oxygen) sensor on bank #1, sensor #2. This post-cat sensor is used for monitoring the efficiency of the catalytic converter. The converter’s job is to reduce emissions out the tailpipe.

Code P2272 can be caused by a vacuum leak, fuel delivery issues, exhaust leaks, a faulty PCM, or faulty oxygen or mass air flow sensors. Common symptoms of the P2272 code include an illuminated check engine light, poor engine performance, and higher fuel consumption.

2022年5月28日 · 1. What does OBDII code P2272 mean? The code P2272 indicates that the HO2S (Heated Oxygen Sensor) signal is stuck lean on Bank 2 Sensor 2. 2. What are the common symptoms of OBDII code P2272? Common symptoms of code P2272 may include poor engine performance, rough idling, decreased fuel efficiency, and the illumination of …

2024年12月11日 · The P2272 code indicates a problem with the O2 sensor, specifically on Bank 2, Sensor 2. This situation arises when the sensor consistently reports a lean condition to the engine control unit (ECU). Understanding this code is crucial for maintaining your vehicle’s performance and emissions standards.

2021年3月29日 · P2272 is a general diagnostic trouble code. It means that the “bank 2” downstream oxygen sensor (behind the catalytic converter) is continuously sending voltage that indicates a lean air/fuel mixture. This does not necessarily mean that the vehicle is running lean (although it can, but usually doesn’t).

诊断故障代码 (DTC)（如 P2272）是车辆的车载诊断系统 (OBD-II) 用来指示问题的特定标识符。P2272 代码指的是 O2 传感器信号卡在稀薄状态（气缸 1，传感器 2）。 了解，这些故障代码 (DTC) 有 5 个字符：1 个字母，4 个数字。P-Powertrain 表示故障代码的位置。

P2272 is an OBD-II generic code for the engine control module (ECM) detecting the O2 sensor for bank 2 sensor 2 after the catalytic convertor is stuck lean. What causes the P2272 code? The O2 sensor for bank 2 sensor 2 is stuck in the lean voltage output when tested and stayed lean for a certain amount of time during ECM testing.

When dealing with the P2272 Code for an oxygen sensor signal stuck lean, start by checking Bank 2, Sensor 2. Test the sensor's voltage using a multimeter. If it's faulty, replace it with a quality Bosch or Motorcraft part. Troubleshoot the fuel system to address the issue.

氧感測器的作用是測定發動機排氣中的氧氣含量，以修正噴油量，從而使發動機獲得最佳空燃比。 在OBD故障碼中，你經常會看到第幾排第幾個氧感測器的說法。 第1排是指氣缸1所在的那個 …

2025年2月1日 · The P2272 trouble code is a diagnostic trouble code (DTC) that indicates an issue with the oxygen sensor signal, specifically stating “Oxygen Sensor Signal Biased/Stuck Lean (Bank 2 Sensor 2).” This code is part of the OBD-II system, which monitors various engine parameters to ensure optimal performance and emissions control.
