P0170 fault code
#1
After changing the injectors, fuel filter, cat converter, O2 sensors, stepper motor, potentiometer, crank angle sensor, temperature sensor, thermostat, engine block & head gasket, brake rotors & pads, rear brake cylinders & brakes, radiator, oil filter and two front tires I thought I had finally managed to get to the end off my problems BUT Oh no, this old girl decided to throw in a few more for me to fix. After clearing the old codes I discovered that one more had been added P0170, this reports FUEL TRIM MALFUNCTION (Bank 1) & the causes being either a vacuum leak, faulty O2 sensors, maf sensor, oil sensor, ignition coil, fuel pressure.
So after I checked for leaks in fuel line & found nothing, I don't have a MAF sensor, brand new O2 sensors, clean oil sensor & new coil I finally found that the air filter housing cover had a broken connection where the breather hose connects. So now with a new (2nd hand) cover fitted & code cleared the old girl is running like new all apart from a few bushes underneath that need changing, lower arms and power steering boot.
I will finally get to the end I hope.
