Hello guys !

I've just managed to get my hands on an OBD reader based on ELM323, and here's what I've got on my 2000 V40, 1.6L 16V, read with DigiMoto, ScantoolNet and others (same results):

1). Error codes:

P0102 Mass or Volume Air Flow Circuit Low Input
P0113 Intake Air Temperature Circuit High Input

I couldn't reset them issuing a "04" or using software, although the car runs smoothly and properly and I have no "Check engine" light on - bulb isn't defective.

2). MAF reading showed 2g/s at idle, and about 5g/s at 3000rpm

3). Air temp sensor showed "66", with engine warm and cooling liquid temp of 90 Celsius, car standing still, also at idle

4). Engine load at idle is about 18% constantly, and when engaging A/C it raises to 23-25% and remains there

Are those correct ? It seems like the engine load is pretty high, or is this how it should be ? What should I look for next ? Does anyone have a PDF or some papers with what value these parameters should have ?

Thank you a lot !

Any Vaccum leaks?

after 230km on the freeway,this little bugger ate 18.3 liters of petrol.this leads to 8.3L/100km.I rode at cruising speed of 130-150km/h. is this normal or too much ? i've seen Volvo reports something like 7L/100km.is the MAF or the tep sensor to blame ? and what's with the engine load ? 18% at idle ?

Im not really sure about the Load. We can't drive with our setup to watch the loads.

Make sure there is no vaccum leaks first. Yes a mass flow could cause a problem.

Engine load wasn't measured in driving conditions.OBD reported the engine load at idle,car in neutral,no lights or A/C.I'm interested if this could lead to higher petrol consumption,or is a sign of malfuncion (worn bearings,sticky valves,etc).My ideal is to make this car comfortable,silent and low-gas consumer.

Thank you !
