2020年6月14日 · What does the OBDII code P0112 for Intake Air Temperature Circuit Low Input mean in a Mercedes-Benz? - This code indicates that the Engine Control Module (ECM) has detected a lower-than-expected voltage from the intake air temperature sensor.

In this video we're taking a look at the intake air temperature sensor. Common trouble symptoms if this sensor fails includes improper idling and poor driving characteristics. On many late model...

2014年7月15日 · Try unplugging and re-plugging the connector to the MAF sensor. I doubt cleaning the MAF sensor would help but it couldn't hurt if the above didn't fix it. Cleaning the MAF is really just to clean the very sensitive fine wire the air flows over to gauge air flow.

2020年7月13日 · The P0112 code indicates that there is a low input signal from the Intake Air Temperature (IAT) sensor circuit. This sensor is responsible for measuring the temperature of the air entering the engine, which is crucial for the engine control unit (ECU) to adjust the air/fuel mixture for optimal combustion.

2017年7月18日 · P0112故障码，适用于所有汽车制造商，意思是进气温度（IAT）传感器1电路低 （第1排） (Intake Air Temperature Sensor 1 Circuit Low (Bank 1))。 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：“ P0112 ”，即可获得对应故障码解释和解决方案。 背景知识：进气温度（IAT）传感器的作用是将发动机的进气温度以电压信号的形式输送给电子控制单 元 （ECU），为喷油修正提供一个参考依据。 如果电子控制单元（ECU）检测到进气温 …

2024年8月21日 · When your car shows a P0112 code, it’s like the computer is getting incorrect “cold” signals from the air entering the engine, even when it’s not. This sensor helps adjust the fuel mix based on air temperature, so wrong readings can make the engine run rough, use more gas, or even have trouble starting.

2020年7月13日 · Code P0112 Description The Intake Air Temperature (IAT) sensor is built into Mass Air Flow (MAF) sensor. The sensor detects intake air temperature and transmits a signal to the Powertrain Control Module (PCM).

2024年5月16日 · P0112 Code Explained: Indicates a low input problem with the Intake Air Temperature (IAT) sensor. Common Symptoms: Includes poor fuel economy, rough idling, engine misfires, and difficulty starting. Potential Causes: Ranges from a faulty IAT sensor, bad electrical connections, to air intake leaks.

Short circuit to positive or open circuit.

2024年11月4日 · A P0112 code is triggered when the engine control module detects a low input signal from the intake air temperature (IAT) sensor. Several factors can contribute to this issue. One common cause is a faulty IAT sensor itself.
