The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.

Therefore, the total cost of diagnosis and fixing the P2698 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time.

The P2698 code refers to the Exhaust Aftertreatment Fuel Injector ‘A’ Performance. The exhaust fuel addition injector assembly is responsible for adding fuel to the exhaust system. This injector is controlled by the Engine Control Module (ECM) for 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 exhaust fuel addition injector assembly is mounted on the outlet of the turbocharger sub-assembly.

What are the possible causes of the automobile fault code P2698?

If you see the engine light on or the service engine soon warning light, it could be due to the P2698 fault code. This code is usually caused by a faulty exhaust aftertreatment fuel injector, an open or shorted harness, or a poor electrical connection in the exhaust aftertreatment fuel injector circuit. To fix this issue, you should visually inspect the related 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 P2698 fault code?

If you’re experiencing the P2698 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may have a faulty Exhaust Aftertreatment Fuel Injector or an open or shorted Exhaust Aftertreatment Fuel Injector harness.
