Pinpoint Tests RD: Nitrogen Oxides (NOx): Introduction
WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2019 Ford Transit-350 HD, 2019 Ford Transit-350, 2019 Ford Transit-250, 2019 Ford Transit-150, and 2019 Ford F-550 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Clearing the PCM DTCs erases any PCM recorded freeze frame data. Record any PCM freeze frame information before proceeding.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
This pinpoint test is intended to diagnose the following:
- harness circuits: VPWR, PWRGND, GND, CAN2+, and CAN2-
- nitrogen oxides bank 1, sensor 1 (NOx11) sensor (5J299)
- nitrogen oxides bank 1, sensor 2 (NOx12) sensor (5J299)
- NOx11 module (5K202)
- NOx12 module (5K202)
- NOx11 module and sensor assembly (5L248)
- NOx12 module and sensor assembly (5E145)
