Hi all. The engine management light is showing on a 55 plate Toyota Aygo. Diagnoses is rear Lambda sensor fail. I have been told that these are any easy DIY job to replace. Is this so, and if so any tips ? Also any idea of the best source to purchase a new one ? Thanks in advance.
Any Auto factor should be able to get the part in a couple of days, or have it in stock.
Dpending on how the exhaust has deteriorated over the years you may need a Lamda socket but a spanner may do the job. DON'T round the edges off with the spanner
