guess the fault and win a pat on the back

[kstead]

ok my cerby loving buddies, Who wants to guess the fault, 10 points to the first correct answer (which I will hopefully find out tomorrow)
MIL light came on whilst driving
de-imobilised tone dosent stop when engine is running
I reckon the options are;
crank sensor foooked
lambda/s wonky
throt pots icky
Other than that she is running fine and danndy

any further suggestions welcome and do maplins do a 9 pin-usb lead????

Faulty air temp sensor.

100 amp fuse I've found that dam thing courses
More probs than any thing else on the car

Two faults?

1.Immobliser
2.Mil light is the easy one to fix, it will tell you whats causing the light to come on. Did the light come on at low revs or high?
Guess wise i'm with Gazzab as a duff air temp and the mbe will substitute a value.

Lambads for low rev faults
Crank sensor affects running same with throttle pots

Would low voltage seen by the mbe throw a Mil light? - don't know

[kstead]

well maplins do a lead so tomorrow will tell,
I reckon gazza is loking strong for the points though as i did fk about with the temp sens plug tonight.
Hope a reset should do the trick

If its a case of pulling the plug causing the mil light, putting it back on will turn it off.
Maybe you disturbed the wiring?

Lambda sensor - Its squealing because the AFR is out of range. Probably water in the connector...

Bit of an update this morning, the mil light disappears on idle. And maplins do the lead for a tenner

Exactly what was wrong with mine. Dry out lambda connector, put some electrical contact grease on, reconnect and problem solved.

Getting to the connector was the hard bit!

MIL going out at idle is typical of a lambda sensor problem.

What is it? Amateur night?

Everyone knows its the silver key.

And the winner is.............
Tanguero .....
Lambda 2 is fooooked
Just cleaned the wiring up and still shows as faulty @ a constant 1.8v
Congratulations

It is entirely possible that its showing that reading because that bank is running permanently rich... Its always worth swapping the sensors over to the other bank and seeing if the fault follows the sensor before forking out for another one.
Don't just switch the plugs round though as that will confuse the hell out of the ECU, you need to physicaly swap them round as well.
