bosch oxygen sensor [lambda]

How to bench test an O2 sensor
I gather as long as the meter changes from nearly ONE volt to zero V the sensor is working?

Otherwise try Automotive Service Solutions in Perth. 08 92049888-they usually only deal with trade customers but if you can buy from them sensors should only cost you $60 each or so for genuine Bosch. You might try them for OEM fitment o2 sensors and find price is not much different. Do you realise you should replace both??

Hi, I need to get some pre cat 02 sensors for my D2 in Perth. I've been quoted about $200 each which seems a bit rich. I read your post and just wanted to clarify. So are you saying that I could use generic 0-1 volt Bosch sensors and swap them straight out?

I have successfully fitted an AU-BF Falcon 6 cylinder O2 sensor to a D2. I also acquired a loom plug off a wrecked Falcon and made a short patch harness using the plug off the old D2 sensor to convert the AU sensor to fit the D2 loom plug. That way either the AU sensor or the D2 sensor would fit without further mods. The patch harness wires were crimped together and heat shrink covered to do that job. I used to pay under $70 for good quality AU sensors, not sure how much they are now.

Hey Bee-utey,,
you ever heard /read/had one thats done this?

as this engine was doing a fair imitation of a stationary steam engine at one point.

Failed head gasket or block >>>> poisoned O2 sensor, yeah, it's pretty common throughout the auto industry. It's also a favourite LR theme I believe. ;)

I wouldnt have said favorite - - - - :angel:

You should only be using the OEM sensors by Bosch. The aftermarket units do not work well with the D2 ECU. Here is the pre-cat sensor which has the Orange connector. It is plug and play, do not waste your tIme and money on the cheap knock-offs because you will be replacing it in short order. The cost ranges anywhere from $60-$120 so shop around for a deal. No sense in paying $50 more than necessary.

And the downstream or post-catalytic converter O2 sensor, OEM unit designated with the gray connector. O2 sensors should be replaced in pairs, (both upstream, then both downstream units) or all of them at the same time for several reasons. There is a right way and a wrong way to do things, and you always get what you pay for. The BOsch ECU system is very particular and tends to be incompatible with parts that are not also genuine, OEM BOsch. You will end up paying more in the end for trying to save a few bucks on aftermarket parts while wasting a month swapping new-in-the box parts twice or thrice over. Same goes for oil seals and gaskets.
