Other than subaru and ebay, where can i get a sensor that will be suitable for a 94 wrx? i got a generic 3 wire off ebay and its sensor range is outside limits on ecu so doesnt work quite right.
Thanks for any info.

Get a BOSCH LS02 Universal sensor. I got one from my local motor factor for £48 including vat. The OEM item is a bosch unit.

The three wires have 2 x black & 1 x white. You need to solder or make a suitable connection from your old wires. earth\power connect to either of the black wires and the signal connects to the white wire.

I removed my heat shields to gain easy access and IIRC the lambda is 22mm spanner. I needed the blow torch though as the old unit was solid.

Hope this helps

 

nice one mate. Thanks
