What does NOx Catalyst Efficiency Below Threshold mean?
When a P20EE is stored in a diesel powered, OBD-II equipped vehicle, it means that the powertrain control module has detected that catalyst efficiency is below threshold for a certain engine bank. It makes the catalyst last longer and allows fewer NOx emissions to be released into the atmosphere.
What does code P20EE mean?
What Does Code P20EE Mean? OBD II fault code P20EE is a generic code that is defined as “SCR NOx Catalyst Efficiency Below Threshold Bank 1”, and is set when the PCM (Powertrain Control Module) detects that the catalytic converter on Bank 1 is operating below an acceptable or allowable minimum efficiency threshold.
What does p20ee stand for in SCR NOx?
P20EE is SCR NOx catalyst efficiency below threshold bank 1. Often they replace the SCR catalyst device as a fix. P20EE is SCR NOx catalyst efficiency below threshold bank 1. Often they replace the SCR catalyst device as a fix.
What does p20ee Ford mean on a catalyst?
P20EE FORD Meaning The Selective Catalyst Reduction (SCR) catalyst is monitored to ensure it is capable of NOx conversion. The concentration of NOx upstream of the SCR is calculated based on a model. NOx concentration downstream of the SCR is measured with a NOx sensor.
Can a p20ee code cause SCR to be disabled?
Any stored SCR related codes may initiate the SCR system being disabled. The stored code P20EE should be considered severe and addressed as quickly as possible. Catalyst damage could result if the code is not rectified quickly. What are some of the symptoms of the code? Symptoms of a P20EE trouble code may include:
What does the OBD II fault code p20ee mean?
What does the OBD code p20ee mean for SCR NOx?
What does this error mean? OBD code P20EE means SCR NOX Catalyst Efficiency below Threshold Bank 1 Issue.
Why is SCR NOx catalyst efficiency below threshold?
SCR NOX Catalyst efficiency below threshold bank 1 might have been possible due to any of the following reasons: From our experience, the most common issue with P20EE error code is faulty Nitrogen Oxide Nox control unit sensors.
What Does Code P20EE Mean? OBD II fault code P20EE is a generic code that is defined as “SCR NOx Catalyst Efficiency Below Threshold Bank 1”, and is set when the PCM (Powertrain Control Module) detects that the catalytic converter on Bank 1 is operating below an acceptable or allowable minimum efficiency threshold.
What does p20ee mean on a catalytic converter?
NOTE: It should be noted that the presence of code P20EE rarely indicates a failure of a catalytic converter itself, and that other codes relating to the reductant injection system are almost invariably also present when code P20EE is present.
