Question

Hello!!!! I keep asking the same question but I really need some help about it , we'll it happens that I had a chemo engine light and it came up that it was the oxigen sensor b1 s1 p 2238 , and I bought the sensor and I changed , but it happens that the light still there and everytime i delete the codes the light show up after 3 seconds , anyone can tell me please what is this for ? I went to another mechanic guy and he told me that probably it's not the right sensor , probably he is right? Or it's something else ? Please what can I do about it

Answer 1

P2238 Oxygen sensor pumping current circuit low (for A/Fsensor)  (bank 1 Sensor 1)

This would be the wrong sensor , or a open circuit for the A/F sensor . If what you have is a airflow sensor that is correct for this vehicle then you would need to look at the harness area for the A/F sensor, what the ECM see is a open sensor circuit
