修复代码P0031或P0037日产Altima

如果你的日产Altima有P0031或P0037代码,你就会发现传感器加热器的问题。 氧气传感器在满工作温度下工作。 为了加快加热过程,日产增加了一个脉冲调制加热器。 ECM根据发动机转速向加热器提供脉冲功率。 由于低转速时排气量小,ECM决定向加热器提供几乎100%的工作周期功率。 由于RPMS当发动机转速超过3600转/分时,ECM会完全关闭加热器的电源。

保险丝15(15A)通过红/黄线向传感器供电。 在发动机运转的情况下,检查该线是否有12伏电压。 如果你的加热器有12伏电压,检查黑线是否有良好的接地。 该接地是由PCM脉冲控制的。 如果你发现传感器没有接地,就沿着它回到ECM并在那里进行测试。 如果ECM不提供接地,你可能必须更换PCM。

如果氧传感器接收到12伏电压并接地,那么传感器中的加热器就坏了。
