Oxygen Sensor question?

[jnr1]

Hey,
I just got back from Advanced Auto and had my check engine light code read.The printout says:

P0155
02 Sensor Heater
Circuit Malfunction
(Bank 2 Sensor 1)


Question is,which one is that?Front or rear?I have the V6...Thanx in advance.

i'm assuming you have a V6 cali spec. bank 2 sensor is the one that goes into the rear precat. the heater in the O2 sensor (these sensors heat up when the car starts through a heater element) is broken... you'll have to buy a new one. i paid $175.00 at the local mitsu dealer.

i paid $75 here in florida for a universal bosch sensor, now my car runs better than ever. where are you located here bro?-----> jnr1


edit: with the universal you have to splice and use the stock connector into the one that comes with the bosch unit

Is it still free to get your Check Engine Light read? Dealer wants $60 to just check it.
