Not really.
The computer takes data from the O2 sensor and coolant temp sensor among others to decide what the mixture will be.

06 bmw 525i codes p0174, p0171, p1338, p0340, p0365, and p1315


codes p 0171 and 174 refer ti system too lean
codes p 0338,340,365 refers to crank. and can shaft position sensors
code p1338 again is camshaft position sensor
code p1315 again is camshaft position sensor
too lean can be from fuel pump pressure too low
and position sensors can be wiring , connections sensors.
Involved in all these , one of the possible causes is the ECM
IF it is possible get a serviceable replacement ECM unit and substitute it first as there is no point in replacing all the rest if the ECM is faulty
could be water in the connections , corrosion etc
it is always suspect when so many different codes suddenly appear at the same time

97 ford expedition has a code 171 and 174 bank 1 and 2 lean what do i do to fix this


Code 171 and 174 are for bank 1 and 2 running too lean. The engine has compensated as rich as it can go, and it is still to lean. This does not necessarily mean your mixture is bad, but something (a sensor) is telling the ECM to correct lean. The oxygen sensors alert the ECM to how lean/rich the exhaust is, and then the ECM trips a code. Maybe you have a bad oxy. sensor, but since there are 4 of them (2 per bank), I don't think they could all go at once.

I have a peugeot 206 1.4 hdi 2004 getig no fule to injectors is ther a fule pump in boot .do they have a fule cut off button


You can check the pump anyway, turn the key in ignition so dash lights come on, you should hear the pump come on for a few seconds. This sounds silly but have you also checked the fuse, also have you had the fuel filter changed? I am guessing there is fuel in the tank??...lol.
