Hi all-
New to the forum. I have a 2005 MPV that is throwing a P0154 and P2197. I'm looking to replace the O2 sensor. What is the best way to approach this problem? It looks to me to do the following:

1. Remove the radiator hose just above the sensor.
2. The sensor is just below. Remove and replace the sensor.

My question is this: what is the best tool to use to remove the sensor? It looks to be too tight to fit an o2 socket plus ratchet. I was thinking something like one of these. Thanks.

 

no experience with o2 sensor replacement on that vehicle...i own 2 different style sockets for o2 sensors...typically just use a bunch of socket extensions and whichever one of these sockets will work best for the car...good luck

The tool you are looking at works very well for tight area O2 removals. If you are sure that the sensor is the issue then you don't have to worry about damaging the wires attached to the sensor. Just make sure you disconnect the harness.
The tool you are showing to use is actually safer than the conventional socket style that both DIY and mechanics often times dame the HO2 & O2 sensor both removing and replacing.

I should mention that your DTC are not definitively towards a bad sensor and may be small exhaust leaks or both sensor and leaks so keep that in mind.

 

Yeah, I'm not 100% sure it is the O2 sensor, but I have it in hand already so figured I'd go ahead and replace it. I got a deal on it from Rock Auto and now I know why.....it was a return. Antiseize on the threads and so on....Of the two I mentioned, I think the Tekton is the better option. I think the electrical connector will fit through the wrench opening.

 

Many HO2 and O2 sensors come with anti seize on the threads . They learned a long time ago how many without it get cross threaded when installing them.

I have all 3 mentioned and a few more sensors tools but the Amazon type over all works the best for me in most cases.

 

My first O2 sensor. Should have known they would have anti-seize on them from the factory. Thanks much.

 

One last thing about O2 sensors and rock auto. Don’t buy the no name or brand that is uncommonly known. You get what you pay for in quality when it comes to HO2 and O2 sensors. Pay a little more for the quality known brands .

 

Thanks. I'm actually a Toyota guy, but working on my Mom's MPV. Took me a while to figure out that it was a Ford V6 in there. Went with Denso....figured it would be quality. I totally agree with your sentiment on parts.

 

Funny thing I am not really a Mazda guy I just own one and love it. Its a daily driver with upgrades. Lol

 

No luck with the Amazon wrench or the Tekton (at least from the top). Going to try a long 3/8" extension with wobble and see if I can get a o2 sensor socket on it.
