P2210 is a diagnostic trouble code (DTC) for "NOx Sensor Heater Sense Circuit Low Input Bank 1". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

The P2210 trouble code detects an issue with the NOx sensor heater circuit.
P2210代码是一种通用的OBD-II故障代码，可检测到银行1中的一氧化氮和氮二氧化氮（NOX）传感器的问题，该传感器是容纳第一缸的发动机库。动力总成控制模块（PCM）根据温度和下游氧气传感器的排气组成数据确定每个催化转换器的NOX传感器的理想传感器电压读数。当PCM指出NOX传感器电路电压读数离应位置太远时，将检测到P2210代码。
P2210故障代码通常是由催化转化器故障引起的。但是，这个问题通常比此问题更复杂，因为由于额外的车辆组件有缺陷或失败，催化转换器通常已经停止工作。有缺陷的质量空气流量，歧管气压和冷却液温度传感器是催化转化器故障的常见原因，广泛的泄漏，受污染的油和不当燃料使用情况也是如此。P2210代码也可能是由上游或下游氧气传感器或有故障的NOX传感器触发的。
The P2210 trouble code will usually be accompanied by the Check Engine Light illuminating on the vehicle’s instrument cluster. This may be the only symptom, but the vehicle may also experience serious engine performance issues, ranging from the minor (hissing noises and acceleration hesitation), to the severe (constant stalling or a non-start condition).
The P2210 code will be diagnosed using an OBD-II trouble code scanner. A trustworthy mechanic can use the freeze frame data from the scanner to assess the P2210 code, and look for additional trouble codes that are present. If other codes are noted, they should be addressed in the order in which they appear. The mechanic will then reset the trouble codes, restart the vehicle, check to see if the code has returned. If the code is absent following this reset, then it was probably erroneously triggered, or the result of an intermittent error.
If the P2210 code returns after the reset, the mechanic should begin with a visual inspection of all electrical components that could be impacting the oxygen sensors, NOx sensor, or catalytic converter. Any shorted wires or damaged connectors should be replaced. The exhaust system should then be checked for leaks, which are a common cause of catalytic converter failure.
Next, the technician can use a temperature gun to note the temperature of the exhaust pipe both upstream and downstream of the catalytic converter that is being inspected. If the noted temperatures to not match the manufacturer’s recommendation, the catalytic converter is probably defective, and the mechanic should continue with a thorough inspection to find why the catalytic converter has failed.
The mechanic can then inspect the upstream and downstream oxygen sensors, as well as the NOx sensor, to make sure that they are in working order.
Any time a component is repaired or replaced, the mechanic will reset the trouble codes and restart the vehicle, to again check to see if the code returns. This helps the mechanic know when the issue has been resolved. However, even if the P2210 code disappears, the technician may need to continue with the inspection, to make sure that the root of the catalytic converter failure is found.
The most frequently made mistake when diagnosing the P2210 code comes from a failure to properly follow the OBD-II trouble code diagnosis protocol. Mechanics should follow the protocol step by step, at all times, to be sure that all diagnoses and repairs are efficient and accurate.
It is very common for the catalytic converter to be replaced without any attention being paid to what caused the converter to fail in the first place. It is also common for oxygen sensors to be erroneously replaced.
P2210故障代码不会总是阻止汽车驾驶。但是，对于汽车来说，没有启动条件或其他严重的发动机性能问题是很普遍的。因此，一旦指出，应立即解决故障代码。
Possible repairs for the P2210 code include
氧气传感器故障代码很常见，伴随P2210代码。在这种情况下，当解决氧气传感器代码时，通常会解决P2210代码。
