hi, the oxygen sensor or lambda sensor for its proper name is located in the exhaust it will either be before or just after the catalitic converter it will have two wires going to it and its just bolted into the exhaust downpipe and the wire connects to the wiring harness near the engine itself, the sensor itself is not cheap to buy but you can replace it yourself make sure you check the exhaust for damage leading up to the sensor as any damage to the exhaust such as a whole in exhaust can cause the sensor fault you have been getting if their is no fault with the exhaust then change the sensor and this should then solve your problem.

Let me know how you get on or if you need further assistance ok

p0172 is--system to rich ( bank 1). an oxygen sensor on bank 1, detected a rich condition ( to little oxygen in exhaust ) v6-v8 - v10 engines, bank 1 is the side of the engine that has # 1 cylinder. causes could be a vacuum leak in a hose, a dirty or bad maf sensor, or fuel pressure or delivery problems.

SOURCE: Check engine light came on and is giving codes

check for a broken vacuum hose or vacuum fitting(s). you can use a can of spray carb cleaner. while running the engine use the spray to test hoses and fittings. give a little squirt to suspected areas. The idle speed will change when you find a vacuum leak. pay particular attention to the hose to the MAP sensor. There may be a problem with the elelctrical connection to the map sensor, or the sensor itself may be bad.

P2188 System Too Rich at Idle (Bank 1) On a Chevy Aveo I have heard 2 different things that cause this code, 1. Check for any vacuum leaks in the intake , and 2. Check for oil bypass in the cylinders, Personally I don't know which is correct , But figured I could give you an area to check , Good Luck
