What is the P2214 fault code What is the NOx Sensor Circuit Range/Performance Bank 2 failure description? How can I fix P2214 fault codes? What are the causes and symptoms of the P2214 error code?
What is the P2214 Fault code? What does it signify?
Diesel-powered engines produce more particulate matter (PM) and nitrogen oxide (NOx), than gasoline engines. The NOx sensor is used by the powertrain control module (PCM/ECM) to monitor the nitrogen oxide levels in exhaust. The main polluting gas produced by diesel-fueled engines is NOx. If the PCM detects an error in the NOx sensor or circuits, fault code P2214 will be triggered. The code’s “Bank 2” refers to a malfunction in an exhaust system at the engine’s second banks (the side that does not have cylinders).
Mercedes Benzes, BMW, Mercedes Benzes, Volkswagen, Audi and Chevrolet are all susceptible to the P2214 fault codes.
What is the P2214 Fault Code?
Here are some reasons why P2214 should be set.
- – Defective catalytic convertor
- – Damaged or defective NOx sensors
- – Extremely dirty NOx sensor
- – Broken, damaged, melted, or rusty wires and connectors
- – Short or open circuit problems
- – Exhaust manifold leaks
- – Defective PCM
What are the symptoms of the P2214 Fault Code?
These symptoms may be present if you own a vehicle that has the code 2214.
- – Illumination at the check engine lights
- – Higher hydrocarbon emissions
- – Inconsistency of fuel consumption
- – Uneven idle speed
- – Excessive smoke coming from the exhaust
- – Low engine performance
- – Hesitation during acceleration
- – Engine not running
- Engine stalling
- – Other related fault codes
How to Fix the P2214 Fault Code
- – Fixing exhaust system leaks
- – Repair and inspection of all wiring and components as necessary
- – Replacing the damaged catalytic convert
- – Replacing the defective NOx sensor
- – Repair of or replacement of damaged wires or connectors to the NOx sensors
- – Reparing the ground wire of the NOx sensor
- – Clean the NOx sensor
How Serious Is the P2214 Fault Code
Emission-related codes can be applied to steering, suspension, brakes, and other systems. They aren’t as hazardous as malfunctions in system, so they are typically of low to moderate severity. This code can be delayed if there are more critical engine problems.
A P2214 code usually only displays a check engine lamp. In some cases, however, the code may cause the engine to not start or to stall upon starting. If this happens, it is important to fix the problem as soon as possible. If the code is used in other codes, and the fault is not addressed immediately, it could cause damage to your catalytic converter.
