(6) Main Wiring HarnessUse the following list below as general handling guidelines for the NOx sensor and wiring harness.
Do not unplug the NOx sensor cable when the sensor is powered on, damage to the engine ECM may occur.
Avoid impacting the NOx sensor, dropping the sensor could cause permanent damage. If the sensor is impacted, discard the sensor.
Handle and store the NOx sensor in a clean, dry area that is free of contamination and inclement weather.
The sensing unit protective cap should not be removed until the sensor is ready for installation.
Do not paint any part of
