182 Lambda Sensor - Euro Car Parts - Is this one correct?

[M@tt_182]

MOT today and it failed on emissions, my first port of call is the post CAT Lambda and wondered if this one is correct - http://www.eurocarparts.com/ecp/c/R...58e8bca555237fff081a9593a914a40b7379d8&000210

I can get it for about £58 with discount so not a bad deal!

Check the pre-cat lambda first. That is the one that affects the fueling IIRC. The post cat just checks that the cat is working by checking the emissions, and is usually in way better condition than the pre cat lambda.

Cheers guys, going to replace it either way as it was an issue last year also. So I presume it's best to replace the pre cat sensor first?

Yes replace the pre cat one first.
