Technical help me, exhaust problem

[huaweiideos]

hello,
I've got a serious problem, accidentally disrupted lambda sensor, the sensor with 3 wires before the catalyst cistern...
anyone can tell me what problems will disrupted sensor cause?!

Simple answer.

The Fiat Tipo doesn't have a lambda sensor.

Problem solved.

I suspect the last of the production may have, as my 1994 tempra did ; - ).


with ZERO signal from the Lambda probe, the vehicle SHOULD go into " limp-home"
resulting in ;
lack of power / performance ( SFB may say his Tipo doesn't have these either..!!)

Did your Tempra have a "catalyst cistern" as well?

I've replaced faulty lambda sensors on 4 different vehicle makes in the last three years,
(Mitsubishi, Seat, Opel, Peugeot) but none of them went into limp mode.

( @SFB may say his Tipo doesn't have these either..!!)

My faithful and totally rust free 91 - 1.4 Tipo has electronic ignition............ y hasta.

My Tipo 1.4ie DGT '1989 and my Tipo 1.4ie SX from 1995 both have a lambda sensor

....Maybe the carburettor versions does not have it...?

Thanks, that's news to me and Haynes Workshop Manual, where no lambda sensor is mentioned.
I also bought a lambda sensor free 1989 1.6 DGT for spares.
Both of mine have carburettors, so you're probably right.

Do the cars you mention have "catalyst cisterns" as well?

Note to self: Never consider buying anything other than the carburettor version Tipo.

the lambda probe / AKA oxygen sensor,

is a vital part of a FUEL INJECTION system( measuring the stoichiometric mix = "Lambda)"

it would only be "for information" if fitted to a carbureted engine,

Not all fuel injection systems though....
I have an Alfa Romeo GTV-6 with Bosch L-Jetronic fuel injection WITHOUT lamda sensor....

To clarify,
a catalytic convertor (or cat) and lamda sensor would only be fitted to a car with fuel injection, but a fuel injected car would not necessarily have a cat and lamda sensor. No carburettored car would have a lamda sensor/cat fitted as standard equipment because a cat requires better and more precise fuel regulation that only fuel injection can provide.

All 1.4/1.6 petrol Tipo's upto 1992 in the UK had carburettors. Single point fuel injection and cats were introduced in 1992 on late MK1 Tipos. All Mk2 petrol tipos in the UK would have had single point fuel injection and Cats/ lamda sensors.

Since DGT models were phased out and replaced with Tipos with similar specs but without the digital dash in early 1992, with the exception of the 1.6 SX and the 1.9 tdSX Mk1 Tipos, which did still retain the digital dash, it is unlikely that, in the UK at least any DGT models had a cat and lamda sensor or fuel injection.

Just to confuse things, other markets had Tipo's fitted with single point fuel injection from the cars launch in January 1988.

It's a shame that all this information was posted for huaweiideos, who never came back.
Some of us are now more informed, whilst others are more confused.
