I need to change the front (pre-cat) lambda sensor on my 06 2.5 Hawk WRX as it's starting to fail.

Does anyone know the part number or where I can search for it? Been using aunty google and search function on here with no luck so far.

Don't wanna ring my Subaru garage as I know them rather well and they have already quoted me to change it.

Thanks in advance.

 

PM me your vin, I'll return you the part number

Thanks Rob. You're a gent indeed.

Top job.

 

Just a quick question to anyone that may know, once I've fitted my new pre-cat lambda sensor will I need to get the ECU reset? I've got a diagnostic tool, but don't think it can reset the ECU.

Thanks

 

Always best to reset the ecu as it will have fuel correction % learnt from the old sensor.

 

Poop. That's what I thought too. Will have to buy myself a cheap reset tool then.




Thanks again Rob.
