hi,
plugged maf back in, reset everything and drove it 50 mile,
now i have both o2 sensors again and the p1340
so,,, the maf could be faulty throwing the p1340 code or when its unpluged the dme uses the default settings but when the mafs pluged in its trying to ajust the timing and fuel ratio but cant due to the o2 sensors.
looked at the o2 sensors real time,
the rear are both fine and giving a constant reading which is exactly what it should be.
the front o2 sensors which are throwing the codes are flat lined reading zero?? this seams odd to me not even reading 0.001 ect, i need to plug a new one in before i fit it maybe.
has anyone else had an o2 sensor reading zero?
signal implausable, if it was a connection it would say open circuit.
also the system stayed open even when warm, never closed loop. this will over fuel it surely
picking up the new vent line and connection piece in the morning then off to work to fit it, also replacing oil filler tube o ring whilst its in bits..
then will buy 2 o2 sensors and plug them in.
cheers
