P0056故障代码定义

The P0056 trouble code signifies that there is a problem with the heater control circuit in the bank 2 sensor 2 oxygen sensor.

P0056代码的含义

该代码意味着银行2传感器2氧气传感器由于氧气加热器电路中的问题而无法正确加热。

是什么原因导致P0056代码？

The P0056 trouble code is caused by an incorrect amount of resistance in the heater circuit. This is most often caused by a faulty sensor due to the high temperature that the heater operates at.

What are the symptoms of the P0056 code?

该代码的唯一症状是，由于氧气传感器需要更长的时间才能达到其工作温度，因此车辆发射的发射可能会增加。排放的增加是导致检查引擎灯亮起的原因，以便可以尽快修复车辆。

How does a mechanic diagnose the P0056 code?

• The first step in diagnostics for a P0056 trouble code is to complete a visual inspection of the wiring for the bank 2 sensor 2 oxygen sensor.

• Many times this code can be set due to wires being damaged by being routed incorrectly or by road hazards.

• If no problems are found during the visual inspection the next step is to use a multimeter to measure the resistance of the heater circuit in the oxygen sensor itself. The service manual for your vehicle has a ohm specification for a good sensor.

• 如果传感器的电阻不在规格中，则它是故障的，需要更换氧气传感器。

• 如果传感器检查确定，那么我们必须检查电路的其余部分从动力总成控制模块到库2传感器2氧气传感器的连接器的电阻。接线的正常读数小于一半欧姆。

• 如果发现其余的接线是好的，则可能是罪魁祸首是动力总成控制模块本身。

Common mistakes when diagnosing the P0056 code

The most common mistake is not performing any diagnostics at all and simply replacing the bank 2 sensor 2 oxygen sensor. Majority of the time the sensor is the problem, but from time to time there can be other issues as I pointed out earlier.

P0056代码有多严重？

P0056故障代码不是最严重的故障代码。如果条件恰到好处，动力总成控制模块可能会损坏，但不太可能。

What repairs can fix the P0100 code?

The most common repairs for trouble code p0056 is thereplacement of the bank 2 sensor 2 oxygen sensoror repairing the wiring in the heater circuit.
