Technical Lambda sensor

[varesecrazy]

Thanks a lot. I have done some photo to my car. May you show me more or less where are the lambda probes located?

Thanks again.

IF it were petrol you'd see the wires and head of from where you'd taken pics above..,

I'd forgotten your vehicle wasn't the UK norm.

ok - it's a diesel,
the diesels seem to have the probe under the floorpan , around the exhaust flexi joint

see these schematics for the JTD 1.3 grande Punto. http://eper.fiatforum.com/eper/navi...INT_MODE=0&EPER_CAT=SP&WINDOW_ID=1&GUI_LANG=3

that's as good as I can do.., not having access to a 1.3 JTD..,

Mine is 1.3 mjet. So you mean the probe is located in the back attached to the silencer? It's not under the bonnet?

that's how ePER shows it..,

Finally I think I find out where the lambda sensor is on my IDEA. The precat lambda should be that in the image:

I have checked the wire and the lambda cable go to a black box:

Someone can explain me what is this? I checked for the number on internet and it would be a relay control unit (r41gj glow plug relay). Any explanation on why the lambda cable is connected to this box?

Furthermore, I have measured with a tester the OHM in the lambda PIN and all the pin took two by two have more or less 2.5ohm. Is the lambda working fine?

FPT - is the fiat-group engine manufacturer,
NGK - obviously Japanese ignition parts company

:idea:look in panda or Grande punto section,
same engine..

The problem is still there... :bang::bang:

I have changed the lambda probe for the ECU error "P0130 - 02 Sensor Circuit Malfunction (Bank I Sensor 1)" but after an ECU reset and a mileage, the engine light appeared again.

I have checked the wire between probe and ECU and everything seems ok. Any suggestion? There is some fuse related to the O2 oxygen sensor B1S1?

Thanks a lot for helping.

hi again,
personally - I would post what you've done so far in a new TECH section thread..as the Idea section is REALLY quiet.

Hi,

If I'm not mistaken, B1S1, refers to your pre 02 sensor. This sensor is located before your

catalytic converter. And, if I'm to assume correctly, you will have another 02 sensor after your catalytic converter.

I know petrol engines will have both 02 sensors, but I wasn't aware that diesels had them as well.

Mind you its a 2011 model....................mines only a Panda 1.2 petrol 2007.
