This code means there's a problem with a special injector in your car's exhaust system. It's supposed to help clean the exhaust, but it's not working right.
The P2698 code indicates that the performance of the exhaust aftertreatment fuel injector 'A' is not within the expected range.
The exhaust aftertreatment fuel injector is responsible for injecting fuel into the exhaust system to aid in the reduction of emissions. Code P2698 is triggered when the Engine Control Module (ECM) detects that the injector's performance is not as expected, which could be due to a malfunction or inefficiency in the injector itself or its control circuit.
• Check Engine Light is on
• Poor fuel efficiency
• Increased emissions
• Possible engine performance issues
• Faulty exhaust aftertreatment fuel injector
• Wiring issues in the injector circuit
• Clogged or restricted injector
• Faulty ECM
ECM: Engine Control Module
Injector: A device that introduces fuel into the engine or exhaust system
• Perform a visual inspection of the injector and its wiring.
• Use a scan tool to check for any other related codes.
• Test the injector for proper operation and flow.
• Check the wiring and connections for any signs of damage or corrosion.
• Replace the faulty exhaust aftertreatment fuel injector.
• Repair or replace damaged wiring or connectors.
• Clean or unclog the injector if possible.
• Update or reprogram the ECM if necessary.
• OBD-II scanner
• Multimeter
• Fuel injector cleaning kit
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado
• Ram 2500
• Regular maintenance and inspection of the exhaust system.
• Use high-quality fuel to prevent injector clogging.
• Keep the vehicle's software updated.
Engine Performance
• Do not ignore the Check Engine Light.
• Get the vehicle inspected by a professional mechanic.
• Avoid driving the vehicle excessively until repaired.
Check with the vehicle manufacturer for warranty coverage on emissions-related components.
This code has been more prevalent in diesel engines due to their complex aftertreatment systems.
Moderate – Should be addressed soon to prevent further emissions issues.
Driving with increased emissions may violate local environmental regulations.
• Engine at operating temperature
• Vehicle driven at various speeds
The exhaust aftertreatment fuel injector is typically located in the exhaust system, near the catalytic converter or diesel particulate filter.
Q: Can I drive with a P2698 code?
A: It's not recommended to drive for extended periods with this code, as it may lead to increased emissions and potential engine performance issues.
Q: How can I prevent this code from appearing?
A: Regular maintenance and using high-quality fuel can help prevent clogging and ensure the injector operates correctly.

Fitment Required · Vehicle-fitment part
Relevant when catalyst-efficiency or emissions faults persist after proper diagnosis.
Catalyst-efficiency faults sometimes point toward converter problems after proper testing.
Catalytic converters are highly vehicle-specific and should not be purchased by code alone.
