P2202 GMC code

Code P2202 is a code indicating the engine NOx sensor on bank 1 is not working and the engine will have reduced power to make sure the engine is not putting out NOx. It will do this by running rich to lower combustion chamber temperatures.

Where is the NOx sensor located?

Zitat von Youtube: And you can see the module mounted up on the frame rail there.

What is NOx sensor bank1?

The P2201 code’s definition is “NOx sensor circuit range/performance (Bank 1).” It’s triggered when the powertrain control module (PCM) detects an issue with the nitrogen oxide sensors. The nitrogen oxide sensor measures the amount of nitrogen oxide expelled in the exhaust.

What does code P229F mean?

What does the Mercedes Benz P2202 P229e P229F error codes mean? This is a generic code to signify the electronic control module of your vehicle has detected that the sensor signal of your NOx sensor is low on bank one. It is caused by the ECM receiving lower than expected voltage from the signal wire.

Can I drive with faulty NOx sensor?

In short, the answer is yes, you can drive a car that has a faulty knock sensor. That being said, you may not want to. The prolonged driving of a car that has a bad knock sensor can cause a lot of damage to the engine.

How much does it cost to replace a NOx sensor?

U029D normally means Lost Communication With NOX Sensor ‘A’. 2 NOX sensor equipped in Dodge Ram Van. One seated behind turbo, 61955-44600, called as sensor bank A with dealer price US$700-US$900, is responsible for monitoring the engine out NOX level.

Can a NOx sensor be repaired?

The NOx sensor is a very complicated component and can be expensive to repair however, it’s often not actually the sensor which is causing the problem but the lambda probe inside the exhaust which tests the NOx levels which has malfunctioned, and this is something which can easily be replaced.

How do you reset a NOx sensor?

Go to the System menu, select Engine, then choose the specifics for your vehicle and go to Functional Tests, followed by Special Functions. At the next screen pick Adaptations then scroll down to find Reset Learned Values Of NOx Sensor Upstream And Downstream Of SCR Catalytic Converter.

What causes NOx sensor codes?

The NOx sensor is shorted internally or the wiring is shorted causing the low voltage. The NOx sensor is contaminated or clogged with soot.

What does code P20EE mean?

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.

What is code P2201?

The P2201 diagnostic trouble code indicates that the nitrogen oxide (NOx) sensor circuit is out of range or has a performance issue. The purpose of the NOx sensor is to measure the amount of nitric oxide and nitrogen oxide in the exhaust system, and when the storage capacity of these harmful gases has been reached.
