Correct me if I'm wrong but the O2 sensor is on Bank 1 sensor 2 !? And won't you chance having to reprogram your PCM module??!!!! Which can end up costing around $1,500.00 to reprogram the module plus both the keys of both the keys about the keys have to be reprogrammed with the module.
Poor wiring or connections, including those related to the O2 sensor, can potentially affect multiple systems, including: *Related Systems* 1. Powertrain Control Module (PCM) 2. Engine Control Module (ECM) 3. Transmission Control Module (TCM) 4. Anti-Theft System 5. Fuel Injection System *Potential Issues* 1. Fault codes 2. Engine performance problems 3. Transmission issues 4. Stalling or rough idling 5. Decreased fuel efficiency *Why?* 1. Shared electrical circuits 2. Interconnected systems 3. Common ground points 4. Wiring harnesses *Precautions* 1. Consult repair manuals 2. Use proper tools and procedures 3. Disconnect battery before starting work 4. Double-check connections and wiring The PCM module, being the primary computer controlling engine and transmission functions, can be particularly sensitive to electrical issues.
no, O2 sensors have a plug & receiver type connector. The PCM will likely run rough on change out because the PCM is a PID controller that has self correcting gain. As your old sensors aged their signal changes and the PCM corrects for that. Once you get a new sensor the PCM has a step change in signal and it takes a few minutes to recalibrate. sensor 1 is upstream, sensor 2 is downstream.
The lower sensors are easy but the upper pre-cat sensors are a pain especially the one in the front is very difficult to get to and sometimes you have to use a torch to heat the exhaust manifold up just get the pre-cat sensors to break loose. Like i said the front pre-cat sensor is the worst of all 4 to get to. I have changed many ox2 sensors and some break loose quit easy but some are completely stuck and like i said you have to use a torch to heat the exhaust manifold up around the sensor just to get to break loose. Automobile manufactures don't make easy at all when comes to changing alot of parts on a engine. Just wait till you have to put a alternator on a Ford 3.0L engine in a Mazda Tribute/Ford Escape, now that is a real pain.
I did get to it by climbing over the top of the engine and building a daisy chain of fittings. including swivels. Unfortunately i broke the honeycomb on bank 1 sensor 1 and ended up junking the vehicle because of an electrical issue.
I can't speak to that model as I don't own it. However you can trace the exhaust lines back to the manifold. You should be able to find the cats that way. Then it's just a matter of locating the sensors before and after.
O2 sensors always come in pairs pre and post cat. The pre cat sensor feeds back post combustion O2 levels to modify fuel inputs. The post cat sensor measures cat performance based on the change in o2 levels from the pre cat
@@spencerhayward4803 i have a p2273, no power, and pipe is burning hot right next to this sensor. I’m being told I need to replace the cats. So confused but found the location now thanks

From my understanding the O2 sensor doesn't directly contact the anti-theft module, but it's still a chance you're taking !??

Did you find an easy way to replace Bank 2 Sensor 1?

@@stevenburnett133 what was the electrical issue?
How about 2004 mazda mpv with the 3.0 v6

Bro I changed two from underneath I thought only 3 four fuck I have 03 tribute 3.0 l es v6 4x4 their is 4

Where’s the bank 2 sensor 2 located?
Did you find it working on mine now
need this one I'm thinking it's the one by the oil pan>??? My pipe near it is glowing red! burning rich.
@@MysterSer333 it’s the one right up front easiest one to get to
@@user-ql4bc8tx5p my bad bro I must haven’t noticed your comment. It’s the closest one up front easiest one to get to.
