Default p0036, p2181, p0140 errors.

Just wondering if anyone could give me some advice on these error codes(p0036, p2181, p0140) . p2181 is not really a problem because the water pump was replaced at the dealers about six months ago, so its hopefully the ect sensor, ill find out tomorrow. the other two, not too sure about. p0140 o2 sensor 2 in bank 1, easy fix?(by easy fix i mean reasonable to do on your own) or should i take it to the dealer. if i fix the o2 sensor will the p0036 error go away? just looking for some advice.

thought also i should mention its a 2003 jetta gl 90,000 miles 2.0l engine

On a 2.0 you have to remove the heat shield to get to the 02 sensor. I wouldn't want to do it myself but it's about an hours worth of labor to do I think. You could try it yourself.

Mine was super easy to get to... I am not sure what your engine looks like, but all you need is the o2 Sensor Socket-bit for a socket wrench and your golden. took my like 15 minutes to get it all squared away, but it's not like it was my 3rd time doing it or anything...! lol.

Jack the car up on passenger side, put your jack stand up, get a 10mm bit for a socket wrench to open the black box where the sensors are, remove the BLACK sensor (pre-cat), use your fingernail to lift up on the little retaining clip and pull it off, un-clamp the wire to the heat shield, then go under the hood to wrench off the sensor and pull it through/under the heat shield, put back in reverse order. we love it.
