I would like to know where the oxygen sensor is on my 2000 GMC Jimmy. Can anyone help me locate that?

Check out the link. click on the images tab. You really need a service manual.

Oxygen sensors shoult be replaced about 65 thousand to 85 thousand miles.

replace fuel filter, air filter, spark plugs, wires, distributor cap /rotor, if you have one. new oil with your filter ? just thought I'd ask, have a auto parts store pull code to see why your service engine soon light is on. this will tell you what sensor needs replaced, I'll bet its the oxygen sensor !

Hello jerryparker6,
The image below shows the location of the crank position sensor.

I hope this helps.

There are 4 O2 sensors. 2 are located before each catalytic converter and 2 are located after the converters.

P0161=O2 Sensor Heater Circuit Bank 2 Sensor 2,
oxygen sensor after converter on passenger side.

Inside trans. pan at the rear of the valve body. They have a wire clip which holds them in.

do you have access to a scanner to check the computer , possibly the computer has gone bad .

9141 does not exist I will assume it is DTC P0141 HO2S Heater Performance Bank 1 Sensor 2

The VCM has the capability to monitor this process by using the Heated Oxygen Sensor (HO2S Bank 1, Sensor 2). The HO2S (Bank 1, Sensor 2), located in the exhaust stream before the catalytic converter, produces an output signal which indicates the storage capacity of the catalyst; this in turn indicates the catalysts ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S signal will be far less active than the signal produced by the Heated Oxygen Sensor (Bank 1, Sensor 1).
When the HO2S temperature measures below 360°C (600°F), the sensor will not produce any voltage and will behave like an open circuit. This will result in an Open Loop operation.
The HO2S heater provides for a faster sensor warm-up which allows the sensor to become active in a shorter period of time and remain active during long extended idle. The DTC P0141 determines if the HO2S is functioning properly by checking the response time of the sensor. This DTC is a type B DTC.

it's at the front of the engine and below the and left of the front of the crank shaft.
dis-connect negative attery cable
dis-connect the electical connector to the sensor
un-bolt it and pull it out
reversr for installation
