Yeah, they've got one on each side of the engine (L & R exhaust manifold) and also one at the catalytic converter. I bet they're a ***** to remove

This car probably has four of them. It will definitely have at least one in the exhaust manifold. It may have one in each manifold and two more below the catalytic converters. They started putting them both above and below the converters so they could tell when the converters need changing. I am not sure what year that was though.

I have a 2001 PT Cruiser I have replaced my cam sensor and my crank location positioning sensor the come to find out that it was a broken wire on my crank sensor pigtail Yahoo runs but only for about 2...

I know it's a long shot, unplug your 02 sensors, see if it helps? You see, your asd relay sends voltage to several systems, primary voltage to the coil--fuel injectors-- 02 heater circuit and whatever else. I have heard of 02 heater circuit shorting and stealing voltage from other components.
Any applicable trouble codes? Could be other issues? As far as the cam and crank sensors, I usually want to check wiring circuits before replacing anything. With three wire connector, that is ref voltage--ground--signal. Sometimes ref voltage and ground are shared by other systems.

Year--make--model would be helpful?
Downstream 02 sensor is usually after the cat. The code number usually tells you which sensor, bank1--bank 2 and so on, where applicable.

I have a 2001 Ford Escort ZXT I need to locate the o2 sensor and MAF sensor I need a diagram to change both of those

the mass air flow sensor is in the ducting to the throttle body. the o2 sensors are on the exhaust pipe. looks very much like a spark plug with a wire extended from itself. the maf will also have wiring associated with it. replacement of 02 sensor requires a special wrench. disconnect battery for a few minutes to clear all previous codes. replace parts and then reconnect the battery. allow computer to relearn in a short trip.

Locate 02 sensor

On the I6 engine, the precat sensor is located on the passenger side of the engine right below the exhaust manifold. Easty to get to, unplug the sensor and use an 02 sensor socket to remove. Post cat sensor is underneath after the cat. The connector to unplug is located in a difficult position, near the top of the transmission. I find that moving yourself toward the rear of the car and reach in the easiest. As opposed to reaching in right above the 02 sensor.

O2 sensors are located in the exhaust manifold near the Catalytic converter.
Some cars have the 02 sensor before the catalytic converter, some behind, and some before and after.

Simply locate the "bung" that contains the O2 sensor, and you will see the sensor connected to wires.
This is the best way to locate them.

I replaced my 02 sensor and cleared the code po 155 still comes on on my 2002 sonoma please help

which sensor did you change, the correct one is located on passengerside on exhaust pipe near the top. not after the converter or on the driverside, that truck if it has a 4.3 v-6 engine it has 3 to 4 sensors located 2 before the cat and 1or 2 after the cat, you want the one on passengerside closest to the top near manifold. hope this helps.
