Sir, my vehicle's dash continue blinking with 4lo plus engine light steady on. I have spend so much money in different garages but no luck and no permanent resolution. They only reset my dash and it goes but after sometimes or next day it comes back. I need your advice how can I permanently fix it?


Appreciate your advice.
Thanks regards,
Umair

Hi Umair,

We can definitely help. We will need a little more to go though before we can narrow this down to possible causes.

Let's start with what diagnostic trouble codes are in the computer. This will point us in a clear direction.

Next, can you provide a complete list of parts, if any that have been replaced. Also, if they have made any repairs that did not include any parts, like a wring repair. You don't need to give a long story for each, just a list of parts/repairs is all we need. I just don't want to recommend something that has already been done.

Thanks

That should be correct. Bank 1 is the side that has cylinder number 1. If you have doubts, you can swap the sensor side to side and see if it moves. If it moves then you know it is the sensor.

As long as you don't have an exhaust leak, the sensor sounds like the issue.

Please let me know if you need anything else.
