The P269A code refers to the exhaust aftertreatment fuel injector ‘A’ circuit high. The exhaust fuel addition injector assembly is responsible for adding fuel by a control signal from the Engine Control Module (ECM).

This injector is used for two different controls: Particulate Matter (PM) forced regeneration and PM reduction. Low-pressure fuel is supplied to the exhaust fuel addition injector assembly by the feed pump in the supply pump assembly. The P269A code indicates that there is an issue with the circuit high in the exhaust aftertreatment fuel injector ‘A’.

What are the possible causes of the P269A automobile fault code?

If your engine light is on and you’re getting the P269A fault code, it could be due to a faulty exhaust aftertreatment fuel injector, an open or shorted harness, or poor electrical connection in the circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can one visually inspect the related wiring harness and connectors to fix the P269A fault code?
