Hi
This car came to me few months after I had it initially repaired...
Video here: • Vauxhall/Opel Astra J ...
Came however, with a different fault...
Follow me on this video to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!

That was crazy ECT affect IAT and other.
But it was good to see Job Done nicely 😊☺️
Thanks!
👍👍👍
Thanks for sharing Bro👍
The best thing is how you explained the dtc's for an open or short circuit👍
Another one fixed😉
Stay Safe👍
Thanks!
For watching and for your comment!
Interesting how the radiator temp sensor affected the IAT and ECT sensor figures ... Top job as always Luis cheers 👍
Thanks Igor...
First time I worked on one of these... lol
It was a bit 🤔 at the start...
😜
👍👍👍
That was too easy!
Thanks for sharing L.
😊
👍👍👍
Almost a year later 😁 good video as always. Cheers.

There is a field remedy for this fault from Vauxhall’s which requires a new multi plug temp sensor and seal along with new terminals for the multi plug all parts are included in the rework kit available from Vauxhall’s dealers good video tho
Was not aware...
Thanks for the info!
👍👍👍
LM Auto Repairs not a prob I thought I would say as you helped me when I asked for advise but most dealers stock this kit as was a very common rework when I worked for them there was also a rad fan rework for the Astra j also

👍👍👍
seems simple but very interesting to see that sensor affects both ECT and IAT readings
Perfect working sir it's very interesting and thanks for this guide
Thanks!
👍👍👍
thanks for another useful video, just a comment .. because I only have a multimeter I would have taken the easy route first, test for open/short through the sensor
Multiple ways to approach something like this...
Thank you for watching and for your comment!
Both ways are just as easy.
Testing continuity and looping to read the data take exactly the same amount of effort and time.
Nice work Luis
Thanks!
👍👍👍
Good job and good diagnostic strategy👍👍👍
Thanks!
👍👍👍
I'm having a problem connecting turbo pipes. To inlet manifold on astra j 1.4turbo
Manifold behind the engine. Basically please can i see how is connected
Astra j 1.4 turbo A14net engine petrol
Thnx verrymuch for je best information
No worries...

Hi great video easy to follow for a novice diy mechanic like me.
Would this fault cause the in cabin heater to blow warm even with the AC on? Have same symptoms as this except it's a service light not a engine light on the dash. Also when I'm driving the problem seems intermittent. Just changed the etc this morning but still happening.
Could do...
But check all the other possibilities...
Have you scanned the car?
Check live data and check temperatures etc...
👍👍👍
@@LMAutoRepairs my readers just a cheap one, i can see the engine isn't overheating though, and it gets up to temp nicely so i doubt its the thermostat either.
Appreciate the reply.
The ECU didn't report any codes for IAT and ETC. If there was a problem there should should be a code. Why was there -40 for the IAT and ECT? Maybe the ECU doesn't report what it actually reads? Also the 140 degress C is weird. If we assume it follows the OBDII PID for ECT (0105) the answer for radiator temperature sensor is one byte (A=0 to 255). With a temperature range -40 to 215 (A-40). It showed -40 when open in open circuit, but only 140 when in short circuit. Maybe the ECU saw -40 from the radiator sensor and said OK, report all sensors as -40?
Possibly...
👍👍👍
thankss for sharing luis good job
No worries...

My partner has 1 4 turbo 2015 model eml on and off. I believe its a sensor on the back of the engine what sensor would this be any ideas
You "believe it is a sensor "?
Don't guess... it can become very expensive very quickly... if you just start to throw parts at it in the hope that fixes it...
Scan the car first, and go from there...
👍👍👍👍
@@LMAutoRepairs petrol air flow leak or something but would that be camshaft sensor
Interesting the way you checked that, but did you clean that connector? Just wondered if that was part of it.
Yes... connector cleaned...
👍👍👍
Why do they have 2 sencor one for the radiator one for the actual engine temperature
So you can tell what the temp is coming out of the radiator. Imagine if the radiator was plugged and had bad flow, it would be pretty useful to see that data at that spot, correct?
Correct...
@@mikesabin8568 now that makes sense that's actually a neat feature to have
What about the Autel Maxys 908? Don't use it anymore? By the way, nice job! Congrats for the channel.
I do...
Is my main tool...
Was just testing this one at the time...
No longer have it...
Thank you for watching and for your comment!
Good job sir
Thanks!
👍👍👍
You made a schoolboy error here. You found severe corrosion on the sensor plug. Enough to prevent circuit connection. The sensor may or may not have been faulty but you changed it anyway, possibly wasting £30. Because you didn't test the original sensor you don't know whether it was faulty. The rest of the car looks terrible under the bonnet. 10 years old but no undertray to stop water ingress. No wonder there's corrosion.
For £30, was no point to risk it...
The plug for the sensor was sealed, for the water to be inside, would mostly had to come through the sensor... the pin was also quite corroded...

Backlog...
Planned backlog...😉

@@LMAutoRepairs all good video's
What does ect stand for
Engine Coolant Temperature
If I am not mistaken...
👍👍👍
Good job as always but too nice and easy . Nah just kidding . It just can´t be all headache jobs .
😊
True...
👍👍👍
You must have a huge back log of videos if you didnt post this for at least 10 months....

Yes I do...

Another Vauxhall....
Indeed!...

Forever will be or BMW or VW or vag because they break down more than others
I wonder what they will use when they rut out of alphabet letters in naming their cars
🤔🤣
