Check Engine Light / Code
 

A little help.

My check engine light recently came on ('02 S60 Non Turbo). I went to the local Autozone to have the code read. The reader detected two codes both came up as:

P0037 Bank 1 Sen 2 Heater Circuit Low

What is this? How serious? How expensive?

I am not sure ...it might be Oxygen Sensor..

Somewhat expensive
Bad O2 sensor.

Bank one, sensor two, oxygen sensor.

I guess all inline 5's are bank one. Find a diagram and replace it yourself and save $$

I bet a dealer will charge you $350 to replace, net cost of sensor is anywhere from $70 to $180 depending...

it could be that your volvo oxygen sensor is bad and needs a replacement.. good luck
