Code P208D RAM Description
The P208D diagnostic trouble code (DTC) specifically relates to the Diesel Exhaust Fluid (DEF) Reductant Pump Control Circuit being detected as operating at a low voltage. In vehicles equipped with Selective Catalytic Reduction (SCR) systems, the DEF reductant pump is responsible for delivering the DEF fluid from the tank to the exhaust stream to reduce harmful nitrogen oxide emissions. When the control circuit for this pump is operating at a lower voltage than expected, it can lead to a variety of issues.
Common Causes of P208D RAM
- Faulty DEF reductant pump
- Wiring issues in the control circuit
- Malfunctioning control module
- Corrosion in electrical connections
- Low DEF fluid levels
Symptoms of P208D RAM
- Illumination of the check engine light on the dashboard
- Reduced DEF fluid levels or warnings related to DEF system
- Decreased fuel efficiency
- Engine performance issues, such as reduced power or hesitation
- Failed emissions test due to increased nitrogen oxide emissions
How to Fix P208D RAM
- Perform a thorough inspection of the DEF reductant pump and control circuit to identify the source of the low voltage issue
- Test the electrical connections for corrosion and repair or replace as necessary
- Check DEF fluid levels and refill if necessary
- Replace the DEF reductant pump if it is determined to be faulty
- Clear the DTC and reset the vehicle's computer system to ensure the issue has been resolved
Cost to Fix P208D RAM
The typical repair costs for addressing a P208D code can vary depending on the specific cause of the issue and the labor rates in your area. In general, replacing a DEF reductant pump can cost anywhere from $300 to $800, including parts and labor. Additional costs may be incurred if wiring repairs or control module replacement is required. It is advisable to consult with a professional mechanic to get an accurate estimate based on your vehicle's make and model. Labor rates at auto repair shops can range from $80 to $150 per hour, so it's recommended to shop around for the best prices in your area.

Frequently Asked Questions about P208D RAM Code
1. What does the OBDII code P208D mean on a RAM vehicle?
P208D indicates a "Diesel Exhaust Fluid Reductant Pump Control Circuit Low," meaning the control circuit for the DEF pump is experiencing low voltage or electrical issues.
2. What are the common symptoms of code P208D on a RAM truck?
Symptoms may include a check engine light, reduced engine performance, DEF system warnings, or the vehicle entering limp mode.
3. What causes the P208D code to appear on a RAM vehicle?
Common causes include a faulty reductant pump, wiring or connector issues in the DEF pump circuit, a bad reductant control module, or a blown fuse.
4. Can I drive my RAM truck with the P208D code active?
Driving with the P208D code is possible but not recommended. The vehicle may enter limp mode, and unresolved DEF issues could lead to emissions non-compliance or further damage.
5. How do I diagnose the P208D code on a RAM truck?
Start by inspecting the wiring and connectors for damage or corrosion, check the DEF pump operation, test the circuit voltage and continuity, and scan for additional related codes.
6. How can I fix the P208D code on my RAM vehicle?
Repairs may include replacing the DEF pump, repairing or replacing damaged wiring or connectors, replacing the reductant control module, or addressing any blown fuses.
7. How much does it cost to repair the P208D code on a RAM truck?
Repair costs vary, but replacing a DEF pump typically ranges from $500 to $1,200, depending on labor rates and parts pricing.
8. Can a clogged DEF injector cause the P208D code?
While a clogged DEF injector is unlikely to directly trigger P208D, it can lead to other DEF system issues that may indirectly contribute to this code.
9. Does the P208D code affect emissions compliance on a RAM truck?
Yes, the P208D code impacts the DEF system's ability to reduce emissions, potentially causing the vehicle to fail emissions tests.
10. Do I need to reset the ECM after fixing the P208D code?
Yes, after addressing the issue, clearing the code with an OBDII scanner is necessary to reset the ECM and confirm the repair.
