Updated: Oct 16

What is P0050 Fault-Error code?


The P0050 Fault-Error code is an OBD-II (On-Board Diagnostics - Second Generation) error code that indicates a problem with the vehicle's emission control system. This error code indicates a problem on the heating circuit of the vehicle's exhaust gas oxygen sensor "A" bank 2.


Meaning of P0050 Fault/Error code:


The P0050 Fault/Error code indicates that there is a problem with the heating circuit of the vehicle's exhaust gas oxygen sensor "A" bank 2. This sensor measures the oxygen content of exhaust gases and helps regulate engine performance and emissions.



What causes the P0050 Fault/Error code?


P0050 Fault/Error code may occur for the following reasons:

  1. Exhaust gas oxygen sensor "A" bank 2 is faulty or broken.

  2. There is an electrical problem in the heating circuit of exhaust gas oxygen sensor "A" bank 2.

  3. Damage or breakage of the wiring of the exhaust gas oxygen sensor "A" bank 2.

  4. Communication problems with the ECU (Engine Control Unit).



Symptoms of P0050 Fault/Error code


P0050 Fault/Error code may manifest itself with the following symptoms:

  • Decrease in engine performance.

  • Decrease in fuel efficiency.

  • Increased exhaust emissions.
