Need to Replace Your Paccar NOx Sensor (2236409)?

You’re driving along and your check engine light comes on, so you pull over to scan for fault codes. The DTC scan tool tells you there’s a problem with your 2236409 Paccar inlet NOx sensor. Your mechanic tells you the problem can’t be fixed, and you need a new sensor. What do you do next? If you don’t want to fork out for a new OEM sensor, and don’t want to risk an unknown aftermarket supplier, why not ask your dealer about Roadwarrior?

What Does a NOx Sensor Do?

A nitrogen oxide sensor measures NOx levels in your semitruck’s exhaust gas and reports back to the ECU. The ECU uses these readings to make sure the SCR is working properly. Most semitrucks have two sensors – an inlet NOx sensor before the SCR and an outlet NOx sensor after the SCR. The inlet sensor tells the ECU how much DEF to inject into the pre-SCR exhaust, and the outlet NOx sensor measures NOx levels in the post-SCR exhaust to measure its performance. This helps your aftertreatment system make your semitruck’s emissions cleaner and less toxic!

What Problems Can My Paccar NOx Sensor (2236409) Experience?

Nitrogen oxide sensors have to be highly sensitive to pick up on fluctuations in NOx levels, but the result is that they are quite delicate. They often fail after about 300,000 – 400,000 miles because of soot build-up from the aftertreatment system. They can also become contaminated by moisture during installation, or due to internal leaks! For this reason, it’s worth being extra-careful if you’re installing replacement nitrogen oxide sensors yourself! If your 2236409 Paccar MX-13 NOx sensor becomes smothered with soot, it will likely mean a DTC, a check engine light on your dashboard and a trip to the mechanic for a replacement!
