ENGINE FAULT LIGHT IS...

ENGINE FAULT LIGHT IS ALWAYS ON DESPITE CHANGING THE CAM SENSOR TWICE!

Mechanic's Assistant: Just to clarify, what are the exact lights you're talking about?

THE CHECK ENGINE LIGHT ON THE DASHBOARD

Mechanic's Assistant: What is the model/year of your BMW?

2000 316i M43 GASOLINE ENGINE

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

YES, CHANGED THE CAMSHAFT SENSOR TWICE, THE IDLE VALVE, ALL THE FILTERS, AND OIL OF COURSE

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I HAVE CHANGED THE SPARK PLUGS, AND MY LITTLE FAULT CODE READER ALSO SAYS FUEL TRIM FAULT?

Hi
The scanner is an Autel maxiscan. The MAF has been changed for a new one, the camshaft sensor code is 0340 and there is no +/- figure for the fuel trim , the code is 0170 haven't tried unpluging the MAF.Tom

hey tom , unplugged and let me know

the 170 could be related to o2 sensors are they original ?

Hi Chad
I disconected the Maf and the engine coughed and died, the O2 sensors are original as far as I know. 17 years old??
That tells MAF working , I would do a smoke test and fuel pressuer test if it passes and changer all the sensors
Sorry for the wait I lost my interest connection ,
