This summary uses the existing diagnostic information shown in full below.
This code means that there is a problem with the part of the car that injects special fluid into the exhaust to help clean it. It's like if the straw you use to blow bubbles got a hole in it, so it can't blow bubbles properly.
The code P2697 is set when the Engine Control Module (ECM) detects an open circuit in the exhaust aftertreatment fuel injector A. This injector is responsible for injecting fuel into the exhaust system to aid in emissions reduction.
The P2697 code is triggered when the ECM detects an open or malfunction in the circuit of the exhaust aftertreatment fuel injector A. This injector is part of the Selective Catalytic Reduction (SCR) system, which reduces NOx emissions by injecting a reductant (such as diesel exhaust fluid) into the exhaust stream. An open circuit means that the electrical path is broken, preventing the injector from functioning properly.
• Check Engine Light illuminated
• Poor engine performance
• Increased emissions
• Possible limp mode
• Faulty exhaust aftertreatment fuel injector A
• Open or shorted wiring in the injector circuit
• Bad connector or poor electrical connection
• Faulty ECM
ECM: Engine Control Module
SCR: Selective Catalytic Reduction
• Scan the vehicle for codes and confirm P2697 is present.
• Inspect the wiring and connectors for damage or corrosion.
• Test the exhaust aftertreatment fuel injector A for proper operation.
• Check the ECM for faults.
• Repair or replace damaged wiring or connectors.
• Replace the faulty exhaust aftertreatment fuel injector A.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Ford F-250
• Chevrolet Silverado 2500
• Ram 2500
• Regularly inspect and maintain the exhaust system.
• Keep electrical connections clean and secure.
• Use high-quality diesel exhaust fluid.
Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if you are not familiar with vehicle repairs.
Check with your vehicle's manufacturer warranty; emissions components may be covered under an extended warranty.
The P2697 code has been associated with diesel vehicles equipped with SCR systems since their introduction to meet stringent emissions standards.
Moderate – While the vehicle may still be drivable, increased emissions and potential performance issues should be addressed promptly.
Driving with a malfunctioning emissions system may not comply with local emissions laws and could lead to fines.
• Engine running
• Vehicle at operating temperature
The exhaust aftertreatment fuel injector is typically located near the SCR catalyst in the exhaust system.
Q: Can I drive my car with a P2697 code?
A: It's not recommended to drive for extended periods with this code, as it may lead to increased emissions and engine performance issues.
Q: How do I clear a P2697 code?
A: The code can be cleared with an OBD-II scanner after repairs are made, but it will return if the underlying issue is not resolved.

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.
