In this video my 2004 Honda Civic has the money light on! It was a quick diagnosis of the P0128 Insufficient Coolant Temperature. We demonstrate the value of test don't guess! Oh and then we run from the cops in the end of the video... -Enjoy!

is it just a coincidence that the scanner showed (deg c) in the description despite it also showing degree Fahrenheit. seeing that 10 deg c is 50 deg f
Nice job. 2007 Nissan Altima 2.5, I have been having an issue with a P0128 which basically triggers when you do not get hot fast enough, so I replaced both thermostats with genuine Nissan as well as the sensor. When I monitor via OBD2, with the AC running, it still does not get hot enough, staying under 185 or so, still do not understand why. With the AC off, the temp works perfectly going to around 205, no code. Just weird with no answers. I am going to take out the thermostats once again to make sure they are facing the correct direction, though I doubt that will make a difference. If anyone has suffered this issue, and solved it, please respond. It is annoying.
Good catch on the scan Data Graph of the drop out in the sensor Goos video as always Eric O @SouthMainAutoRepairLLC
Awww I got a wet face!
Great video Eric! I just got the classic P0128 pop up on my Jeep GC. Im pretty sure its the coolant temp sensor so Im gonna throw another sensor at it! Get ready for the parts cannon haha!
Eric, did I miss it or did you not ever do a video on the actual repair of the Honda Civic with blown head gasket/cracked block? Would love to know what you did to get the car on the road. What ever happened to the car? I watched this and I think 5 or 6 other videos on the car but never saw anything about the major repair.
Had a p0128 in my jeep turns out my temp sensor pig tail was broken
but it does need to be said ….. some time s it is the thermostat…… in my 2005 civic temp needle dropped about 2 thicknesses of the needle when on the hwy … then would rise when back in town …. … done sorted ….. but the seized heater control valve is still an ongoing saga ….
Very interesting issue – as always.
BUT – what happened with the engine on the Hondoo? You went from head gasket and possible rings to programming a key fob and adding tuner lights in the trunk.
Maybe it's just me, but if I ever came to visit SMA, I'd be more interested in meeting Shiba than Eric. I just wanna pet that dog!
I thought this was the Honda that needed a head gasket or the head?
Did Eric repair it yet?
Whatever happened to the engine teardown/rebuild/swap? We go from 3 out 4 bad cylinders and massive blow by to driving home with a wonky coolant temp gauge. Was looking forward to fix of your own car.
What's happened to the civic these days????
Back in the late 80s and early 90s had a few of these, and much tougher to catch and diagnose since we didn't have the graphing or the ffd to look at. Mostly is was a digital readout of live stream data and if you weren't watching closing, sometime you'd miss the drops or spikes.
Oh man, i think Eric is foreshadowing his next video: eBay turbo kit!
There's your problem Lady, It's a Hondooo. I had one for 4 years. Vtechs not a good thing
COOL ENDING! Good tech tip about "testing" the CTS system VS using the parts cannon, starting with the t'stat. Sometimes OBDII Generic testing gets results. I don't know what tester you used, but the software layout is a lot like the Matco MaxMe. Is that a Launch Diagnostic tablet?
Last week I had a PO128 code on a 06 chevy impala. Temp gauge was on the money at like 206 degrees. The outside temperature was 58 degrees Fahrenheit. But the iat sensor was reading 115 degrees Fahrenheit. Unplugged the maf sensor and it dropped to -40. Ordered a new maf sensor and plugged it in before installation. It read 65 degrees. Which was good enough for the chics I run with. Install maf sensor cleared code and shipped
the coolant temp sensor went bad in my 69 volkswagon bug and it took forever to get the parts from germany.
did you fix the engine without a video?
what finally happened to this Honda?
So what happened to all the videos from Hannah and Josh tearing down the Hondoo and do rebuilding the engine?
never caught on why u call it hondoo. it seems like a negative name when in my experience they're the most reliable and what breaks in them is less expensive to repair. ive never had blown head gaskets in hondas. every ford ive owned always resulted in at least one blown head gaskets even with recommended maintenance.
Don't get Sheeba arrested! She's inoceeeent!
as far as i know it could indicate these possible problems leaking or stuck open thermostat, low engine coolant level, insufficient warm up time, faulty engine coolant temperature sensor, engine coolant temperature sensor harness is open or shorted, or engine coolant temperature sensor circuit poor electrical connection
waiting for the mini cooper video if there is one..not a fan just that's its a uk vehicle.. 😊
Usually tapping on sensor will show drops on scanner.
had a dodge neon setting code for high and low coolant temp it happend at 178f it was bad ecm . not the same as you but you need to now what scale computer changes readings
Is Mrs. O's timing belt done?
Eric you need a new hat…. LOL
In case I did miss it, will we see the major repair videos of the Handoo?
You broke it already? 🙄
Time for a 2JZ swap 😍
What a nice floof you have there!
Dog !
tired of today's "Chinesium GARBAGE" change. time to start bolting on manifold, distributor, carb. and POINTS distributor 😉
A thermistor is essentially a substance that changes resistance as temperature changes. And a sudden loss in reading can generally be traced to the connections opening up at specific temperatures/humidity level. Other factors that can cause failure are openings of the shell of the thermistor where moisture can infiltrate and alter the thermistor's chemical substance thereby causing failure. Generally though, such infiltration/failure will not be short lived. That leaves connections as the most likely culprit. I'd check the connector(s) first ahead of condemning the thermistor.
You and your boys ought to wire up a far+ can exhaust on that bad boy…
With that honda, what does the O2 signal look like in those for the signal and the heater? Ive got a heater circuit and wondering where to begin.
That's a great dog.
Thanks for the video.
Eric and Sheba the outlaws XD.
Hey Eric, want to bring my car out to you in the next couple of weeks. How can I get ahold of you to set up appointment? Thanks, Tim
I recently almost got bit on my Eurotrash Beemer, suspecting a stuck thermostat when it was a bad coolant temp sensor.
I first noticed that the cooling fans were on all the time (suspecting slow stop-and-go traffic), but the problem truly reared its head on the motorway when an engine overheating warning came on and the car went into limp mode. I managed not to get rear-ended after the speed suddenly dropped from 75ish to barely 50 mph, and carefully nursed the heap back home.
I connected a scanner (Carly for BMW) which did show the coolant temp at idle being around 95-100˚C (203-212˚F).
Strangely enough, none of the cooling hoses felt significantly colder or hotter to the touch than the others, and nothing seemed excessively hot. Yet the fans were on all the time.
Took the other car and drove to the parts store to get some ammo for the parts cannon: a new thermostat, coolant and a temp sensor. The next Saturday I was fully committed to start changing the thermostat, but for some reason decided to plug in the scanner one more time. The car had been sitting overnight and the engine was cold. Yet the scanner showed the coolant temp to be 90˚C (194˚F)!
So the repair turned out quite easy, only needed a new temp sensor. I do intend to change the thermostat or at least the coolant at some point as preventive maintenance, though.
That's all the bumping of the RL at the traffic lights with your baseball hat ,arm out the window, And you're dog by your side, keeping it real Mr O…🙅🏻
10.4 degrees C on the coolant temp. That's about 51 degrees F. Matches up with IAT data.
HAHAHA! Love the ending! 😂
Coincidently, my neighbor just got a puppy last week and named it Sheba! Not a Husky, though – it looks like a mix of black lab, pit (really wide face, lol), and maybe doberman (has the ears). Nice, mellow doggie. 🙂
Another fine example of "TEST, don't guess!" 😎
Your emphasis on accurate diagnosis is one of the reasons this channel has risen to the top. I didn't realize there is a difference between the OBDII sides and the OEM sides, what a strange quirk of the software. You would have thought the system would be built with some way to put an asterisk on data that is substituted, rather than leaving it to the tech to guess.
Substituted values . . . gotta love chasing your tail. Learned that the hard way
🙂
Did Sheba get a cheese burger???
Great video
