P202D Code - Reductant Leakage
Quick Answer
The P202D diagnostic trouble code (DTC) refers to "Reductant Leakage." This code typically indicates that there is a leak in the reductant system, which is responsible for reducing harmful emissions in diesel vehicles equipped with selective catalytic reduction (SCR) systems. Common causes include Damaged or loose reductant system components, Faulty reductant injector, Cracked or corroded reductant lines. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P202D Description
The P202D diagnostic trouble code (DTC) refers to "Reductant Leakage." This code typically indicates that there is a leak in the reductant system, which is responsible for reducing harmful emissions in diesel vehicles equipped with selective catalytic reduction (SCR) systems. The reductant system uses a liquid reductant, such as diesel exhaust fluid (DEF), to convert nitrogen oxides (NOx) into nitrogen and water vapor, reducing emissions and helping the vehicle comply with emissions regulations.
Common Causes of P202D
- Damaged or loose reductant system components
- Faulty reductant injector
- Cracked or corroded reductant lines
- Improper installation of reductant system components
- Contaminated reductant fluid
Symptoms of P202D
- Check engine light illuminated
- Reduced fuel efficiency
- Difficulty starting the vehicle
- Increased emissions
- Reduced engine performance
How to Fix P202D
- Inspect the reductant system for leaks and damage
- Repair or replace any damaged components, such as reductant lines or injectors
- Verify proper installation of reductant system components
- Perform a leak test to ensure the issue has been resolved
- Reset the check engine light and clear the DTC from the vehicle's memory
Cost to Fix P202D
The cost of repairing a reductant leakage issue can vary depending on the extent of the damage and the specific components that need to be replaced. On average, the repair cost for this issue can range from $200 to $800, including parts and labor. It's important to note that labor rates at auto repair shops can vary, so it's advisable to check with local shops for a more accurate estimate. Additionally, the cost of reductant fluid may also need to be factored into the total repair cost.
