paperclip test

[Albus Dumbledore]

Hi!
I was earlier today going to try the "paperclip" test on my car, and I found the diagnostic port, under the steering wheel, by the fuses.

But, according to the do it yourself guide here, there should be a 10 pin port, but my car doesn't have that. The port has (about..) 12 or 14 holes, and in seven of them there were pins. which should I short circut then??

Any ideas?

You mean 16 pins...   ...and our guide - http://www.omegaowners.com/forum/YaBB.pl?num=1189022687 - clearly shows the pins - ignore topbuzz, its full of errors

Thanks! I've never seen that guide before!!:)

Ok, done the paperclip test. The result was:
71
16
73
31

What does that mean, and what do I do??

[vauxfan2k]

71 = air temp sensor voltage high

73 = air flow sensor voltage low

31 = rpm signal (crank sensor) no signal (are you doing the test with engine running? if not you will get this code)

16 = knock sensor no change in voltage

hopefully someone else on here will tell you how to rectify as I dont have or never had any 8v omegas

cheers

the 16 will cause it to 'hold back', and is probably caused by the cable being trapped somewhere (likely cam cover)

[Albus Dumbledore]

Ok! No the engine was not running when I did the test. The do it yourself guide said that it wouldn't work with the engine running on a 2.0l.

Ok, I'll check the cable on nr. 16. Does anybody know the rest? what it could be?

The MAF ones tend to disappear on v6 engines once other faults fix.

I would recommend cleaning the throttle body and clean the breathers, making sure no air leaks on reassembly, then see what happens...

[Albus Dumbledore]

Ok, I will do that! thanks!

What's MAF?

[Andy B]

Ok, I will do that! thanks!

What's MAF?

Mass Air Flow meter, the first bit after the air filter.

[Albus Dumbledore]

Ok thanks
