Can Mitsubishi check this somehow ?
Yes it is... from Mitsubishi Australia. Its not nearly as bad from Mitsi Japan thoughSo is there anyway you can check the O2 sensor without replacing it ?
according to LeeButts price list its kinda expensive ...
Engine Control Oxygen Sensor . . . . MD189008 . . . . $419.10
you could get a wideband sensor, which isn't much more expensive than a new oxygen sensor, and monitor it with a laptop, and see how it goes. Should be 14.7 in normal driving, 12-13 under normal acceleration, and down to about 10.5 when you're really trashing it.
Well as of today my best fuel consumption figure is 12.4l/100km and that aint real satisfactory considering 160km out of 217km was freeway. Although the disclaimer is - full load, 3 adults, 2 kids and a pile of crap in the back, suitcases and all.
So what are the first things to check?
Injectors?
How can an oxygen sensor be checked as such? Mitsubishi dealer, any workshop?
on the MUTII they can run a datalog on the o2 sensors and check the switching voltages are ok. it will give them a graph and show it switching between 0 - 1 v
We booked the car into Brisbane Tuning and Turbo Centre and they did a diagnose fuel system $109, supply and fit oxygen sensor $245, and carbon clean$220, + GST= Total cost $631.50 Which seems cheep if the oxygen sensors are that expensive.
