RAM P20EE Error Code: How to Fix It

Q: What causes RAM P20EE error code?

P20EE is typically caused by contaminated or low DEF fluid, faulty NOx sensors, clogged DEF dosing injector, or a failing SCR catalyst. Poor quality DEF fluid is the most common cause.

Q: Can I drive with P20EE error code?

You can drive short distances, but the engine will be in reduced power mode. Continued driving without repair can cause permanent SCR system damage and may eventually prevent the engine from starting.

Q: How much does it cost to fix P20EE on a RAM truck?

Repair costs vary from $200-500 for sensors or DEF system components, up to $3000-5000 if the SCR catalyst needs replacement. Most issues are resolved with DEF system maintenance costing under $500.

Q: Will P20EE clear itself?

No, P20EE requires manual diagnosis and repair. The code will not clear until the underlying problem is fixed and the system is reset with a scan tool.

Q: What is the difference between P20EE and P20E8?

P20EE indicates SCR catalyst efficiency below threshold, while P20E8 specifically relates to NOx conversion efficiency. Both codes affect the same SCR system but point to slightly different failure modes.

Abstract

The RAM P20EE error code indicates your truck's SCR (Selective Catalytic Reduction) NOx catalyst efficiency has dropped below the required threshold for Bank 1. This emissions system problem reduces engine power and can cause your vehicle to enter limp mode until resolved.
