Location of the engine oxygen sensor for a 2009 Buick lucerne

There are at least 3 oxygen sensors. There is one on each side of the exhaust system as the exhaust leaves the engine. These are the upstream sensors. The exhaust then goes to catalytic converters. If you have two, there is a sensor after each one. These are the downstream sensors. Before replacing a sensor, uou should determine if it is bad. Trouble codes indicating problems with the oxygen sensing circuits may have many causes other than a bad sensor. Also be advised that a special socket is needed to remove an oxygen sensor.

Does cleaning oxygen sensor clears p0154 fault

code p 0154 refers to heated oxygen sensor (HO2S) 1 bank 2 --no activity detected===causes ---wiring---HO2S--ECM
it also refers to oxygen sensor(O2S) 1 bank 2 no activity detected ===causes --- wiring )2S---ECM
the HO2S is the sensor in the manifold before the cat converter and the O2S is after the cat converter
they can be cleaned in vinegar but they would be showing signs of activity so in this case it is broken wires , bad connections of faulty sensors

Codes p0054 p0141 p0036

code p0054 is
Possible causes - Faulty Heated Oxygen Sensor Bank 1 Sensor 2
- Heated Oxygen Sensor Bank 1 Sensor 2 harness is open or shorted
- Heated Oxygen Sensor Bank 1 Sensor 2 circuit poor electrical connection
When is the code detected?Heater current requirements too low or high in the heated oxygen sensor (HO2S) heater control circuit Symptoms- Engine Light ON (or Service Engine Soon Warning Light)
code p0141 is O2sensor heater circuit malfunction( bank one sensor 2)
there is chance that wire from that sensor is touching,part of your exhaust system,and either is open or shorting to ground

code p0036
036 - HO2S Heater Control Circuit Bank 1 sensor 2check the wire from the sensor for the sign cut or melting,and change the sensor

Car was running then it stopped starting it turns over fine but theres no sign of a spark

according to this

41 Left Heated Oxygen Sensor Heater 42 Right Heated Oxygen Sensor Heater

15 Ignition Output Signal

So you have a couple problems. The car won't start because more than likely the ignition switch has gone bad and needs replacing.

The O2 sensors will cause your CEL to be on and these will need to be replaced as well.

Poor gas mileage

Check Oxygen sensors. There are 2 of them and not very costly. should be $20-25 each. But if oxygen sensors are bad, you should have 'Chek Engine' sign on. Do you get Check Engine Sign ?

Check engine sign appeared on my 2001 avalon , code error p1155, please advise

Appears it is an Oxygen sensor error, they are located in the exhaust system, in the v6, that code indicates the second bank (but unsure which bank that is) Ideally you need to take the car in for service, or at least inspect the Oxygen sensors, the code indicates that teh heater element has failed.

My 2002 hyundai accent 1.5 liters will stall at a stop sign or red light. it won't restart for at least 15 minutes, then die out about a half mile down the road (on a bad day). the car sounds fine when...

This sounds like an O2 sensor problem. These sensors regulate the oxygen into the engine, when they go bad, the engine can't breathe and therefore the car will not function right. If there is no oxygen, internal combustion can be a difficult task for a car. I would see if you could get those sensors replaced and you might be back in business. Good luck.
