Part No. Required For Coolant Temp. Sender

[lagonda 42]

Just replaced the distributor signal cable (here in France, it cost over £40....& I had to cut a chunk off the plug to make it fit!). That seems to have helped....but now the temperature sender for the management system is under suspicion. I have 2, & can only assume both are faulty...car runs crap with one, better with the other (strangely better when it's hanging loose, NOT screwed in!).

Been to the local Peugeot dealer (can't go far without seeing one here), & it seems there are 2 choices....so he's ordered both to compare. Does anyone know the part number of the correct one for my car?! This will help a lot & save me walking away with the wrong one!

 

If it helps, the sender I'm using has "BOSCH 063" on the hexagon, & "0280 130 026" on it's collar. Of course, I don't know if that's the original, or correct one?! Har har I love this car!

OE part No. is : 0242 46 :

... and thats Bosch sender yes .. open up this catalogue :

.. and type OE part No. in the "cross reference list" , click on the red 7.3128 No. and you'll see whole list of Bosch senders which are also suitable under this part No./code .. (theres a few of them from Bosch brand .. and they're fitted to various types/brands of cars so try to buy one in ordinary car part store as it'll be much cheaper than the same sender from Peugeot !)

Hi Damir,

 

Thanks for that, really helpful!

 

Yes, I suspect Peugeot will be double price anywhere else...am amazed at their parts pricing....surely many good cars are scrapped because owners don't feel expense of new parts economic. Last year some swine stole all the arch & door trims, the rear valance, & broke the rear bumper. These parts from Peugeot new came to over £1300.....they're just plastic .... and pretty low grade plastic at that!

 

I tried to find details on ServiceBox, but could only find the upper water housing with the two (other) senders....I recall this is the same picture the dealer here in France came up with...so my guess is that the "two alternatives" he's getting in are in fact those two...so neither will be any use! Thee's a motor factor nearby, will see if they can help. At least the Bosch part number on the one I' have spare is the same as one of those listed.

 

Thanks again

Brilliant! Just been struggling with Service Box to get this too.

Think I'll try the stealer for this tomorrow.

 

Thanks!!

Here (France), I've trust tried going into motor factors opposite (called Talbot 86). Their English was even worse than my French...but anyway, armed with Peugeot part number, they've located equivalent & put it en comande...on order....should have it tomorrow. Hope their price is better than Peugeot's.

 

There might be nothing wrong with mine.....helpfully Haynes just says if ohmeter says "infinity", get another. One of mine reads 1800 ohms, the other 2500, both of which seem pretty high. Having a new one as a back up won't be bad anyway.

Yes theres slight difference in initial resistance value in between these temp. sensors (especially non Bosch ones which are usually supplied as an equivalent part ..) , but that shouldn't be major problem as long as it reacts properly regarding to the coolant temp changes ..

 

Bring the multimeter out set it to 20K (K ohm) and measure the resistance first on stone cold engine and then on hot engine , fully warmed up to the operating temp , if it's fine you'll expect to see results as follows :

 

Engine completely cold (20C) - 2,000 to 3,000 ohms (if the engine coolant is colder than 20C such as near to the 15-10C mark because of the lower ambient temp. the resistance will be higher so around 3,000 to 4,000 ohms will be fine at 10/15C)

 

Engine fully warmed up to the operating temp. (82C) - 200 to 400 ohms ..

 

It'll have to react a bit sharpish as the coolant temp rises ..

 

As the sensor temp decreases the resistance value will increase , as the sensor temp increases the resistance will decrease .. as these ones are NTC principle sensors (Negative Temperature Coefficient)

 

(you can test them roughly on the bench as well , with bucket of cold water and ciggy lighter – measure the temp. of the water first , then immerse the sensor inside hook up the multimeter probes on the terminals and observe the readings , then remove it out from the water and heat it with the ciggy lighter keeping it connected to the multimeter..)

Hi Damir

 

Picked up the new sensor today....it's made by CI (Commercial Ignition), A UK firm...nothing strange...except I'm in France! Anyway, off the car, at around 20 degrees, it reads around 2000 ohms. Fitted it & car seems to run OK, but I've also cleaned up SAD & throttle body, so that might have cured the misfire anyway. So everything's fine....ha ha, never with this car...now I'm having trouble starting...suspect battery is dieing...to be fair, it's got a right to, reckon it's 11 years old!
