Hi Thanks Phong, many thanks for your detailed reply at this stage I can only see one (1) Oxygen sensor after the cat converter but will have a good look Monday did notice a leak on the header to exhaust joint before the cat converter just under the drivers door so brought to ring gaskets to put on Monday not sure if it will help but needs doing intake and exhaust look fine had new intake filter not that long ago and no power problems I service the car every 10,000kms new oil filter etc. just been done so its vacuum or oxygen sensor at this stage will investigate Monday also where will I find the model number and serial number for the engine is it just under the seat ?will look for it Monday they told me they replaced the spark plugs on engine change as I said before the car runs fine just loves to drink many thanks Keiran Had another play with the obd2 reader but still no joy any one have any ideas

Hi Group First Post I have had 2 Toyota Tarago's over the last 17 years first was a 1989 Tarago which some one bent by hitting me in the side so become a boomerang, so next brought a 1999 Tarago 2.4 fuel injected in 2002 had 70000kms on the clock after 11years only has 200,000kms I only live 3 kms to work but the motor went bad (water in oil and oil in water) probably too many short runs so had a Japanese import put in for $3000 not quite sure which engine it came out of, was told the new engine had a crank angle sensor but not hooked up to my car think it was around 2006 model engine unconfirmed (I can get the serial number from the engine if it helps to Identify the engine) and It seems to have the original ECU still in it. The problem I am having is the high consumption of Fuel, normally out of a 60 ltr tank I would get 550kms aprox out of a tank around town , BUT since the new motor went in I get around 450kms to a tank, not sure why the van seems to run fine MAYBE a little down on power for a new engine but does run fine Engine fitter doesn't want to know about it and too much time has now laps to go back So I thought I would have a look at the ECU but have run into a problem I can only finds the one 22pin TIS port on the van which I brought the adaptor for to "MINI VCI FOR TOYOTA TIS OEM Techstream V7.31" off ebay which is OBD2 but fails to communicate to the ECU have I got the right unit? the software TIS settings are not helpful for Australian Toyota's but tried lots of options but no joy so my 2 questions are 1. why the high fuel(gas) consumption ?? 2. how to connect to the ECU with out paying $1000 ?? Many thanks Crustie p.s. by the way I was an Electrician and now after Elect. Engineering Adv. Dip. employed as Electrical Engineer So have a fair understanding of things with wires but I don't know everything and any help appreciated
