Technical Punto HGT mk2b Lambda Sensor Identification Guide

[MikeSalt]

After an evening with MultiECUScan and pulling some wires, I have a definitive answer as to which sensor is which:

Bank 1 Sensor 1 is the pre-cat sensor attached to cylinders 1 & 2 (No. 15 on diagram)
Bank 2 Sensor 1 is the pre-cat sensor attached to cylinders 3 & 4 (No. 13 on the diagram)
Bank 1 Sensor 2 is the post-cat sensor (No. 14 on the diagram)



At the time of writing, the part numbers are:

Bank 1 Sensor 1: 46807454
Bank 2 Sensor 1: 46760867
Bank 1 Sensor 2: 46811313

But do double-check on ePER before ordering.

Hope this proves useful to someone

Cheers,

Mick

just got P0155 error on my hgt and was wondering which lambda is bad
good that someone else played with wires already

1.2 8v lambda fits and works normally in a hgt

He tenido un problema con un dtc, P0170 Fuel Trim ( BANK 1 ) y buscando informacion he llegado a este post.
Seguramente tenga que cambiar las sondas pre- catalizador , el fallo es intermitente.

Gracias por el esquema , pero existe un error, el BANK 1 sensor 1 corresponde a los cilindros 1 y 4. y el BANK 2 sensor 1 corresponde a los cilindros 2 y 3.

Probably have to change the pre-catalyst probes, the failure is intermittent.

Thanks for the scheme, but there is an error, the BANK 1 sensor 1 corresponds to the cylinders 1 and 4 and BANK 2 sensor 1 corresponds to the cylinders 2 and 3.
