2 Engine Management Errors


Recommended Posts

Hi all,

I bought a second hand 2011 focus mk3 back in November. Typically, just outside the warranty, the engine management light came on. I've had it checked, and it has the following 2 errors.

U0418: Invalid Data Received from Brake System Control Module


P2085: Exhaust Gas Temperature Sensor Circuit Intermittent Bank 1 Sensor 1

I've been unable to find much regarding these 2 fault codes - can anyone shed any light on them? What the cause might be? What the fix is?

The car is generally driving okay, but when I switch down a gear (say to overtake) it does take 2 seconds (give or take) to get engine power back to normal and have normal thrust. In these 2 seconds there is no accelerating power, but it will maintain speed, providing I'm not going up a steep hill.

If you need anymore info, please let me know.

Thanks in advance,

the problem is these codes just point you in the direction to look at not that the issue is that item it sounds like a wiring issue it could be a cluster issue it needs looked at more in depth the 2085 from what I found could be a faulty sensor broken wire at the multiplug it both the other again is a wire or sensor worst case its the module
