is it vauxhall only for 02/lamba sensors

[JasonH]

No there are other suppliers on the web (unfortunately I can't remember who I got mine from).

You need a sturdy spanner (not socket) to remove them and plenty of penetrating oil.

Here are some notes I made at the time:

Fault Code 13 is No.1 O2 Sensor Open circuit – drivers side
Fault Code 89 is No.2 O2 Sensor Open circuit – passenger side

New sensor heater element reads approx 8 Ohms.

Old sensors read around 4 Ohms. Should be 4-7 Ohms at ambient. Resistance increases as temperature increases.

Connector   Sensor   Car      Purpose    
      Wiring   Wiring
C      black      BRBL      sensor
B      white      BR      heater -ve
A      white      RTBL      heater +ve

Haynes wiring diagram page 12.42 items P32 and P36 are the oxygen sensors

Fuse to oxygen sensor heater is FV3 in engine compartment fuse box, 30A. Same supply and relay feed the fuel pump. Relay is K44, the second purple one in on the RHS as you look over the passenger wing. (Relay K43 is the first purple relay.)

With engine running and sensor hot should see 0.2V – 0.8V out of sensor out.

I wouldn't worry about using a spanner to try and remove them tbh
Just smash the things apart with a hammer then use a impact / hex socket c/w strong arm to remove 
Its not like your going to be using them again and i've lost count of the times I smashed my knuckles rounded of the piggin things while trying to remove with a spanner

Giving them a taste of oxy-acetylene makes the job MUCH easier.

Then hit them with a hammer

I've never had an issue removing them, good blast of plus gas day or two before and they come out fairly easily

[pauls]

Just been in touch with my stealers and I wont be buying at that price.

Anybody know where i can get them from that are NOT Chinese copies.

Wont be a problem getting them off as i have just had them moved. both not responsing as they should which is why i want to change them.

Branded NGK are always a good bet and are as close as your favourite motor factor.

I've not had a problem with omega o2 sensors....

my method is a little bad for my tools  but I get a (22mm? cant remember) the right size spanner, make sure its securely locked on to the o2 sensor and give it a few clouts with the hammer. easy
