CEL help

[Jdubya]

CEL came on the other day. Here is the codes:

16543 - Oxygen (Lambda) Sensor B2 S2: Response too Slow
P0159 - 004 - No Signal/Communication
16440 - Oxygen (Lambda) Sensor B2 S2: Heating Circuit: Malfunction / Open Circuit
P0056 - 004 - No Signal/Communication - MIL ON
17548 - Oxygen (Lambda) Sensor; B2 S2: Internal Resistance too High
P1140 - 004 - No Signal/Communication - MIL ON


Anyone know which rear O2 this is? I'm assuming there are two, one after each cat.

Thanks!

well you have 4 O2 sensors... one before each cat on each downpipe and one after the 2nd set of cats on each downpipe.

Bank 2, so drivers side. Buy a universal BOSCH 4-wire/heated from a google search... save you LOTs of money.. got mine for 40 bucks shipped..

only thing is, it wont plug in.. you'll have to cut the wires and join.. not a big deal.

Also there are 4.. but B2= bank 2 and S2= probably sensor 2.. so yes its the one you can see underneath the car after the cat.
