P0128 Code and Sensor Location for the 2005 Ford Focus-Episode 27

[@wesleyturner3494]

Your video is a big help thank you. When you went back to autozone to switch the part out was is called a “ cylinder thermostat sensor “ that you needed ?

[@FocusedHands]

Cylinder Head Temperature Sensor

[@LA_Commander]

On the Focus, or almost any other Ford with the 2.0,2.3,or 2.5 liter Duratec motors, this procedure is easier if you just unplug and remove the ignition coil to the #2 cylinder before you start working on the CHTS. Hope that helps.

[@foxhunter1967ful]

You rock.. my 2007 focus thought was toast.. nobody could figure it out.. thanks so much... I have 2 2007 Ford focus courier one with 377000 miles all original drive train.. other with 500000 plus miles.. so funny cause I was so stumped heading 65 Miles plus out of Denver ( overheating on hills stress ) to purchase a 2013 see etc.. car ad was wrong ( automatic ) discovered this video and immediately fixed my car after I did the thermostat the .. water pump as l etc all new hoses.. thanks your the very very very best !

[@FocusedHands]

This is what it is all about! Another Focus saved!!

[@judah0471]

Thank you....that helped me out big time......I have a 08 and its in the same location not on the thermostat and after replacement no check engine light !!

[@FocusedHands]

Nice! Mine i had to replace the Thermostat aswell. Nice work!

[@kentmcconahay6368]

The sensor the guy bought new does not have threads it has an o-ring therefore it will not screw into the cylinder head like the original one that he had taken out look very closely at both pieces and you'll see the original one has threads the new one does not

[@5jjt]

@1:16, the part you pointed to, I thought that was AC because that's the AC compressor, isn’t it? The water pump pulley has 3 bolts. Isn't that how we tell the difference? When i watched how to change the thermostat A1 Auto, on YT, it shows it is located 180 degrees on the other side of the engine. Im not an expert, at all here. Im just trying to generate discussion so we all can be more clear. Thank you for the video. BTW, Ive been searching for repair videos for a 2.3L 2004 ZTW Focus wagon, if that may be the difference. I know Focuses came with different engines.

[@FocusedHands]

The part I was pointing to was / is the thermostat housing. With the top between cylinder 2 and 3 being the TPS.

[@FocusedHands]

I've seen that 00 through 04 engines locations are different though. For example the TH and the TPS are bridge together on the 00 through 04 models. Separate on the 05 through 07 models

[@chavalee2146]

This was a perfectly explained video thanks for taking the time to show and explain.

[@chrisboz8423]

The longer temp sensor is for the 2.3 and the short one is used for the 2.0.

[@FocusedHands]

I have both engines... both the D23 and the D20 have the same sensor... now the D25 is a bit different. This will require soldering if you want to use it.

[@FocusedHands]

well I have all 3 engines lol... now an ecoboost aswell... opps wasn't suppose to say that!

[@Paul_Warren_Wolfe]

Don't know how you got a 21 mm deep socket over the sensor far enough to unscrew it. I've got a 2006 and the deep socket doesn't fit far enough down to do anything... Interesting

[@FocusedHands]

That is interesting!

[@FocusedHands]

Im using the sockets by Pittsburgh

[@FocusedHands]

So after research I found out why yours did work! You need a deep socket without the inner shoulders

[@AlainaFoster-r5m]

Thank you it helped me out

[@greenirish]

Hello I have a 2008 focus 1.4 zetec. Will this be the same as mine. Thanks.

[@FocusedHands]

Nope! Yours is located on the thermostat housing.

[@abmedia5137]

If the coolant gauge isn't working, like not going up at all. Could replacing the coolant sensor help it work again?

[@FocusedHands]

It could. but you also would keep on an eye on the gauge cluster. I'd take an obdII scanner and watch the coolant level rise while looking at the gauge hand.

[@jonathanstreater]

I reset mine... but if this is your issue... it will go away on its on.

[@leonelrodriguez6264]

hi, sorry for my bad english, why difference size? it´s same sensor? in my region only sold me the large, but my car have the short.

[@FocusedHands]

Nope the smaller 1 is for the oil pressure

[@FocusedHands]

The newer model or updated sensor is short

[@FocusedHands]

I have another video explaining it ... you should check it out

Correct the 2 sensors in the video are different. The longer sensor is the right one. The short sensor is for the oil pressure. Autozone sold me the wrong sensor... however i returned it for the right 1. Now if you replace this sensor and the check engine light still comes on. You will need to check the thermostat housing. After that the water pump and after that the radiator.

Yea tune ups help... i think my first problem with the car was the intake manifold runner control.... i watched alot of videos then changed the part. Next was the throttle body... it was sticking.

[@bassjunkie6404]

@@FocusedHands sorry never got back to you, car is completed, and my sensor was a little loose so I hand tighted down the pigtail connector and so far, on my test drives and when I look for codes nothing pops up, what I am noticing is when accelerating when I’m on the highway and getting off or going over like 30mph, the vehicle has a little hiccup, but when the vehicle is an idol its running perfectly fine and smooth, I did have a problem with the threading on the valve cover head to the ignition coil, it was as if they put lock tight and it brought the whole peice out as one, out of the valve head, I torched it and got it to separate jB welded it back to its spot so I can thread the bolt back on but when righting down the ignition coil it came loose once more, so I know the 4th ignition coil isn’t fully compressed down there is like a mm where I can push down on the spark plug, I’m going to replace that valve head, but do you thing that ignition coil is the hiccup? My vehicle never made that movement till now,

[@FocusedHands]

@@bassjunkie6404 I believe so... a loose valve cover wouldnt cause it to hiccup... but loose ignition coils would. Id also check all your intake hoses and breather tubes too make sure you didn't crack anything. If all that checks out... look at coil boots and make sure they are not swollen... swollen boots do not seat well on the spark plug! Yea ive never known of a valve cover to need the torch... they must have used red lock tight lol. You will forsure need a new valve cover if it is plastic!! Otherwise be ready for more leaks.

[@bassjunkie6404]

@@FocusedHands so fast forward to right now, the misfire I’m assuming was the spark plugs I had bought off rock auto, they were the double platinum Ir no gap, and they were actually discontinued from what I found out when I called the bosch 1800 number to see if they were even for my vehicle but they didn’t tell me why they were discontinued, I got a fresh set from the shop and the car is running smooth, check engin light still comes up so I just ordered that sensor off Amazon, so I’m hoping that the sensor that was in your link is the exact fit because on Amazon it says it won’t fit my vehicle, but on the picture looks just like the one I need, should come in, in about a week or two I’ll keep you posted.

[@FocusedHands]

[@Gdawg51785]

Had same issue. Replaced the sensor. ( I did the pig tail splice.) Check engine light went off right away. BUT, after about a mile, it came back on :( So, how does the thermostat set a code? Does it have some kind of sensor on it?

[@FocusedHands]

Now you need to check the water pump and then check the Thermostat. Also make sure you have no air in the cooling system

[@FocusedHands]

The thermostat does not have a sensor for your cars! I believe the Ford Mondeo is the one with the sensor. If the ECU reads the coolant temp too low once you have brought the car up to temp... it will through the P0128 code. Ford Guys usually say it is either the sensor or the thermostat in our cars. I tell you to check the water pump/ air pockets only if you have already changed the thermostat... so we know it should not be the issue. So if I was in your shoes... I'd start with the sensor(which you have done) the thermostat(which you should replace anyway) Air in the coolant lines, water pump, leaking hoses, Radiator (last)... It is almost never the radiator! Hope this helps
