2002 Micra K11 1.0l Lambda Sensors - P0171

[JownCenta]

Hey all,

I'm still having problems on my car with P0171 and a mechanic has come back saying my lambda sensors are the suspects. What are the OEM parts for a 2002 K11 1.0l? From reading on the forum I think the pre-cat is Bosch 0258003256 however no clue on the post-cat.

Cheers in advance

p0171 is a bad maf 9/10 times. The post cat one will never trigger a p0171 as they are only used for checking if the cat works or not.
The coilpack engines use a few different op2 sensors so check the connector if you want to replace them.
