I have 2016 Ford Explorer Sport 3.5 Turbocharged Ecoboost and i have the Check engine light is on, Calle he scanner reads P0420:00-EC - Efficiency of Catalyst System is Below Limit. - Bank 1, P2096:00-EC Concentration of Post Catalyst Fuel Trim System is Too Lean. - Bank 1, P219A:00-EC Bank 1 Air-Fuel Ratio Imbalance.
I nees to chanche Catalyc coverter Bank 1, an oxygen sensor or is something else that i need to check?
Regards;
Further investigation is needed.
Here's what each code indicates:
1. P2096: This code typically indicates a problem with the downstream (post-catalytic converter) oxygen sensor on Bank 1. It suggests that the oxygen sensor is detecting a lean air-fuel mixture after the catalytic converter. This can be caused by issues such as a vacuum leak, exhaust leaks, or problems with the fuel system, like a leaking injector.
2. P219A: This code is specific to the Bank 1 Sensor 1 oxygen sensor and suggests that the signal from this sensor is not within the expected range. This could be due to a faulty oxygen sensor, wiring issues, or problems with the air-fuel mixture.
3. P0420: This usually indicates a bad catalytic converter, but in combination with the other codes, I think this code got triggered because of something more upstream.
It could very well be the sensor itself, but me things it is something more upstream than the sensor.
I hope this helps guide you. I know it isn’t a definitive answer.
Check for exhaust leaks
