Hello all, I hope somebody can help me with this. I have a 2001 BMW 318i with MIL lamp on.Code P0170 "Fuel Trim" is stored and and pending code P0340 "Camshaft sensor position "A" circuit". I have cleared all codes and when I have sorted an oil leak will drive it to see if any codes return. My question is what will cause P0170 to set and can I determine which fuel trim is the problem.In freeze frame Long term fuel trim is -1.6% and short term is +1.6%. Any help will be appreciated, Thanks.
