Diagnostic tool

[krokkie]

Does anybody know which port a 1994 Pajero 3L uses?
I think it might be OBD1, but I'm not sure.
Where can I download software for this, and is it possible to built a scanner yourself?

Posed this to an Auto Electrician mate. and he said...

pretty sure they still have the older mitsubishi connector. Yes u can build a scanner for them using a palm pilot and some software
have seen people using palm type scanners on their earlier EVOs. Can get live data and possibly codes. Maybe only engine stuff tho

the guys off NZMMC forums where doin it a few years back

I have a scan-gauge II which is an OBDII reader, gives real-time display of engine functions, fuel usage etc.
Problem is my cars are all too dumb to talk to it. If anyone wants to buy it, let me know.

What are you trying to do?
If your check engine light has been coming on these fault codes can be checked manually
Most sensors can be tested with a volt meter.

Which version software is it running and how much do you want for it. I might be interested.

Mitsubishi use a MUTT to talk to them. But I have no idea what a MUTT is!

I beleive this to just be the name of the scantool. There are many different brands of scantools around most are very expensive aimed at workshops working on all models of vehicles

We have 3 different scantools at work to give us good coverage of all vehicles

Evolution02 - intro please! What do you do? Where from etc. Sounds like you may be able to help.

TJ, intersting site. Cheers.

No idea what software version, I'll try to find out when I'm back home next week. It owes me about $360, I'd let it go for $255.
I bought it late last year from the Aussie importer.

I'm an auto electrician and am from Timaru
Was shown this site by an other member Raiknn
Am also still saving for a 4Wd

Thanks for all the info, guys.

I am suspecting my O2 sensor has packed up, and want to check it before I actually spend money on it.
But of course I do not want to spent to much on a diagnostic tool.

you can test the oxygen sensor with a good digital voltmeter. Youll need to test the wires at the oxygen sensor plug. One wire will be the signal wire. Between the signal wire and a good earth with the voltmeter you should see a voltage between 0.1 and 0.9 volts. This should vary with different revs and loads.

It is recommended to replace oxygen sensors every 100000km's but know one does until they fail completely.
Oxygen sensors have a small cell in them and work like a tiny battery. As the oxygen changes between the sample air (atmosphere) and the oxygen in the exhaust the voltage varies between 0.1- 0.9. Lower being lean mixture and higher being richer. As a oxygen sensor ages it loses its ability to produce the voltage and reacts slow hence telling the computer the exhaust is to lean so the computer ads more unnessary fuel. This is why they recommend to replace the sensors to keep fuel mixture correct.

If you do need a new sensor price around theres no need to go genuine there are good aftermarket sensors around ie Bosch
Can price you 1 if you tell me how many wires it has

Note: You may have 2 sensors. One in each bank of your V6

[krokkie]

Thanks for the info, I will check and let you know how many wires.

[NJV6]

There is only 1 in a Paj, its in front of the Catalytic converter after the junction of the ehausts

[krokkie]

I found the sensor, and it looks like only one wire. It's inside braid, so I'm not really sure.
How much would a replacement cost?

How much would I be looking at to replace it?

[evolution02]

Sorry for late reply most 1 wire oxygen sensors are around $100

Whats your fault early oxy sensors like the 1 wire didnt really affect anything

[krokkie]

I can smell fuel when I'm close to the exhaust, and I'm getting about 5km on a litre.

[evolution02]

I would be tring an airflow meter first

[krokkie]

Thanks I'll give it a try.
