DI's and DII's take different O2 sensors and the DI sensors cost more.

 

Just got a quote for mine and they are about 99 to 150 new. Ouchy wawa

 

One of the least expensive places to order your 02's from is Amazon, E-Bay has then as long as you don't buy the generic ones, most parts store will average around $80 a piece for 4.

 

Exactly what Mike said, I bought mine from Amazon, $110 shipped to my door for two.

 

I paid $65 or so for a Bosch on amazon



This is the FRONT sensor or one toward the engine.
Not the rear one.


Be well,

The fronts and the rears are exactly the same.

 

Ouch.
Then I have the wrong one in the front.
but, no codes....

 

Rover has 2 different part numbers for the 02 sensors, but the difference could be only the length of the leads (I'm not sure) the part numbers are:
MHK100920 (front) and MHK100930 (rear).

 

For the record then..

Bought this O2 sensor for Amazon:



Using it as Bank 1 Sensor 1 in the front.
No codes for a month.

 

Leads are different length, and connectors are different. Orange Front, Grey Rear
the ox sensor is physically the same. autozone $69.00 last time I purchased.
1 yr warranty. Save your receipt in case it fails..

For the tough ones to get at and loosen cut the wire off and put a nice 22mm
box wrench on it.
