Can you drive with a P20EE code?

Many people do drive with a P20EE code active, but it's not a good idea to do it for very long.

What is SCR NOx catalyst below threshold?

Diagnostic trouble code (DTC) P20EE stands for “SCR NOx Catalyst Efficiency Below Threshold.” This code is logged when the powertrain control module (PCM) detects that catalyst efficiency is below the threshold on bank 1. Code P20EE refers to the selective catalytic reduction catalyst (SCR) on a diesel engine.

How serious is a NOx sensor?

It's important to repair or replace a faulty NOx sensor quickly to protect your engine and aftertreatment system. You can drive for a short time with a faulty one, with the engine running rich and over-using DEF, but the ECU will eventually send your truck into limp mode and engine derate.

What happens if you don't replace a NOx sensor?

The motor may begin to run rough and fuel consumption can drastically increase. Next, the motor may go into derate, or “limp mode,” and finally, the truck may break down and stop running altogether. The nitrogen oxide sensor is not the part of vehicles you want to fail.

Can an SCR catalyst be cleaned?

SCR catalyst systems need to be cleaned to remove contaminants and plugs. If the catalyst is not kept clean and the ammonia injection system is not tuned, ammonia slip occurs.

What causes catalyst system efficiency below threshold?

Catalyst system efficiency below threshold codes are usually caused by a failed catalytic converter. Sometimes it can be result of faulty sensors, circuit problems, an exhaust leak, or computer issue that needs updating. A catalytic converter is a simple device. It's got no moving parts and it rarely fails on its own.

How long does SCR catalyst last?

SCR catalysts have a typical operational lifetime of about 16,000 – 40,000 hours (1.8 – 4.5 years) in coal-fired power plants, depending on the flue gas composition, and up to 80,000 hours (9 years) in cleaner gas-fired power plants.

What causes a NOx sensor to fail?

A major cause of NOx Sensor failure is soot from the combustion process. This can coat the sensor and affect the reading as the sensor can no longer measure the gas effectively. The soot is also abrasive; when larger particles of soot are present in the exhaust gas, the passing stream can damage the sensor.

Can you reset a NOx sensor?

To reset the NOx sensor, it may be necessary to clear any fault codes and reset the catalytic converter learning value stored in the engine control unit (ECU). This is particularly important if the NOx catalytic converter has been replaced. Of course, you can reset the NOx sensor by yourself.

Can I clean my NOx sensor?

A dirty oxygen sensor can cause your “check engine” light to come on, and can also result in your car burning through extra gasoline. If you suspect that your oxygen sensor may be dirty, you can clean it by first removing the sensor from its housing in the vehicle, and then soaking the sensor in gasoline overnight.

What is the life expectancy of a NOx sensor?

The average NOx sensor should last for 50,000–60,000 miles, but many of them fail long before this! Most malfunctions are caused by soot build-up, but NOx sensors can also be contaminated by moisture during installation or from internal leaks.

Why are NOx sensors so expensive?

Complexity and Cost

Another drawback of amperometric NOx sensors is their high cost due to the multiple chamber design and the requirement for complex electronics to detect nanoampere current levels.

Is it safe to drive with catalyst system efficiency below threshold?

This code indicates emissions controls are compromised, but not engine performance. Important to resolve, yes, but not a safety concern.

Can I still drive my car with P0420 code?

Driving your car with the P0420 code will only lead to further damage to the catalytic converter. Plus, the problem can affect other parts of the car, such as the fuel line and exhaust systems. This is why it's important to actively monitor your car's catalytic convertor to avoid other costly repairs.

Can I drive a long distance with a P0420 code?

Yes, it is usually alright to continue driving in the short term with P0420. It does not pose a risk to the driver. Driving long term with this code can damage your engine and exhaust system.
