Hi. I have looked through lots of forums on this code, but please would someone just confirm something!
We have a red engine warning and the error is P0545, exhaust temperature sensor circuit low bank 1.

We have worked out that there are 2 exhaust temperature sensors on the Qashqai +2 J10 (2011). One is nearer the engine and one is nearer the back of the car, after the DPF.

The problem is that both are absolutely in solid and therefore it is difficult to remove either of them and test them. Disconnecting either of them didn't throw up any new errors on the OBD scanner.

This is our thought:

We suspect that the correct temperature sensor is the one nearer the engine - the one described as "in front of the exhaust turbocharger". I can get one on line for about £65 (part 22640).

Would any of you kind folk just confirm that this is correct? We are going to have to destroy the temperature sensor to get it out and it would at least be nice to know that we have the correct one!!

Thanks so much in advance.

I looked at the J11 exhaust (EX) manual which describes temp sensors upstream and downstream of the Turbo and Cat. The J10 manuals don't mention temp sensors...far as I can see? Check amongst these manuals...EX pages:

The generic OBD code you have is described below and ref Cats: (Exhaust Gas Temperature (EGT) Sensor Circuit Low Bank 1 Sensor 1)....Upstream of Turbo/Cat

You could ask here?

Welcome to this forum. Haven't a clue as to the solution, sorry.

Unfortunately we have a lot of new members who ask a question and then we never hear from them again.

Hopefully someone technically minded will respond.
