Fault code P0174 - Engine & Ancilliaries/Gearbox - The Lotus Forums Jump to content

Recommended Posts

MIL light came on today and my OBD reader shows 3 incidents of the code in 2 consecutive trips.  

Code means bank 2 is lean, car has gone into limp mode.  

Idle is fine, car runs fine apart from limp mode.  

Is it ok to drive it? I need to get it to the dealer.

Lean running is not good for the engine (valves burn out, pistons knock, etc.). How far is it to the dealer?

Its about an hour and a half, circa 50 miles.

Looking at the live fuel trim data it does't appear to be running lean all of the time, but has some spikes where the fuel trim can't adjust enough.  Typically the long term trim on bank 2 was making 14% adjustments the 

I can't hear any knocking or pinking and I had to drive it a bit yesterday, the engine sounded fine, smooth idle smooth but limp mode limited acceleration.

Just spoken with Lotus Silverstone, they think its MAF sensor connector issue, a common problem apparently.
