Fitment (Verified OEM Cross-Reference — NO guessing added)

Based on Mopar OEM catalog data and verified aftermarket EPC listings, part number 68146136AC (Bosch 0281006344) is used in FCA diesel SCR (AdBlue) systems, mainly on the 3.0L EcoDiesel V6 platform (Jeep / RAM / Chrysler applications).

Confirmed applications include:

• Jeep Grand Cherokee (WK2) 3.0L EcoDiesel (approx. 2014–2019)
• RAM 1500 EcoDiesel 3.0L V6 (2014–2019)
• Other FCA 3.0L diesel SCR-equipped vehicles

Fitment is strictly based on OE number matching:
68146136AC / 68249510AB (supersession) / Bosch 0281006344

Verified Cross-Reference (Important)

• Mopar catalog confirms 68146136AC is a Nitrogen Oxide (NOx) sensor used on Jeep Grand Cherokee diesel SCR system and is superseded by 68249510AB
• Aftermarket listings confirm interchange between 68146136AC / 68249510AA / 0281006344 for Jeep Grand Cherokee 3.0 CRD SCR systems
• Product listings show it is used as a direct-fit SCR NOx sensor for FCA diesel emissions systems

📌 Key point:
This sensor is part of the FCA EcoDiesel SCR system, and is ECU-coded (inlet/outlet sensors differ and are NOT interchangeable).

Technical Description

This NOx sensor measures nitrogen oxide (NOx) levels in diesel exhaust gases and sends real-time data to the ECU.

It is part of the SCR (Selective Catalytic Reduction) system, which injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 5 / Euro 6 standards.

Bosch 0281006344 is typically used as a downstream (post-SCR) NOx sensor, verifying catalyst efficiency and emissions performance.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor signal or communication faults
• P2200 / P229F / U029E type codes
• Reduced engine power (limp mode)
• Incorrect AdBlue dosing or high consumption

OE / Part Numbers

• 68146136AC
• 68249510AB (updated replacement)
• Bosch 0281006344
• FCA 3.0L EcoDiesel SCR NOx sensor family

FAQ

Is this sensor interchangeable with other Jeep NOx sensors?

No. Even though it looks similar to other FCA sensors, inlet and outlet NOx sensors are not interchangeable due to ECU calibration differences.

Why do Jeep and RAM share this sensor?

Because both use the same FCA 3.0L EcoDiesel V6 diesel SCR architecture, so emission components are shared.

Do aftermarket sensors work well?

Mixed results. Many technicians report that only high-quality OEM or Bosch units maintain stable NOx readings long-term.
