Hi Gang

So my service engine soon light came on when a punter was taking my car for a test drive as I'm selling it, so I need to fix this!

The fuel gauge has been playing up for a while, showing 3/4 to full when it's not. I could live with it and just use the odometer to gauge how much fuel is in the tank.

I scanned the car for engine codes and got P0462 Fuel Level Sensor A low circuit error.

I saw a youtube video of a guy removing both level sensors in his car and cleaning them, so I did that today as all the stores are closed. No change.

I also read that incorrect fuel readings can be from the AC Control module located behind the radio unit.

I did a cluster gauge check, and they are all working fine.

So, my question is what is Sensor A? Is the pump or none pump sensor side?

I have found a used AC Control Module ($700 new, $100 used)

Thanks

 

Did you ever fix the problem to this?…

 

Yes! I did find a solution for this.

The issue was within the AC Control module located behind the radio unit. I think it's behind the top screen and the signals go from the fuel level sensor in the tank, to this module, and then to the fuel gauge.

I was able to source a used replacement module for $50 from a local scrap yard. It was not the correct part number, but identical looking white plastic rectangular unit. As I had the car in pieces and could return the part if it wasn't any good,I took the part home and installed it. Fuel level now worked, but a couple of other nice options on the car had stopped working as this module wasn't the right part number.... So, I went on ebay and found the correct replacement part - shipped up to CAnada.com it was like $70. Installed and boom! All working correctly. I would look at this option first rather than messing with the fuel tank. Removing the pump/level sensors and the old seals, with dirt/road grime etc would only be my recommendation if you check out this control module first. I think the fuel tank is best left alone in my experience. It's pretty easy to get to the control module. Good luck.

 

Could you send the link or part number?

 

It is best to get the part number off of the module that is installed in your car. This will ensure compatibility and retain all features/ functions specific to your car. See this post as it will show you what the module looks like and where it is.

That said, the Unified Meter/ AC Amplifier part number will be 27760-xxxxx. The last 5-digits will be specific to your car.
