Been on the phone to my nearest main dealer today trying to track down the part number of the coolant sensor . I have diagnosed mine as having a problem because the check engine light comes on and when i connect the ecu check wires it flashes "21" - coolant sensor problem? It won't start when this happens and the cooling fans come on. Disconnect the battery for 5 mins and it's fine. Am I right?
The dealer couldnt find the part number or know where it was. I understand from another thread it is under the inlet manifold.
Can anyone help with a def. location and/or part number please?

 

Yep, it's under the manifold and sort of get-at-able if you are a double jointed midget. Seriously, not too bad just not a 5 minuter.

You should be able to quote your chassis number to a dealer and they'll automatically be able to order the right part.

Unless it's an import, in which case you need to call us and we'll sort you out.

thanks Dave , how much are they , it's a UK MY95 ...?

I have had the dealer looking for it for a day now.... today , as i went to pick up some other parts, I explained where it was as roughly I had roughly worked it out from the pdf manuals downloaded from Chris Palmer's site .They still didn't know. They suggested it might be the ECU.... i agreed as far as the ECU was reporting the fault but their lack of knowledge worries me !

 

A whole tenner would do it plus a coupla quid postge and then the VATmans slice. recorded delivery Royal mail would be best.

Call us on Monday if you want. I won't be there but the Mark or Clare will sort you out.

Good Luck David

 

Wont be the ECU, Easily sorted now.. quick phone call to API

nice one Dave, thanxs

Will be on the phone Monday

 

ecu , mmmm, could have sworn i hadn't gone into macDONALDS....

 

?

In case you missed the point i meant that in my experience the sensors do fail and that it has never been the ecu when i have fixed the Fault, A quick call to API will sort you out a new sensor..

Sorry Rob , didn't miss your point, thanks for your post. What I was saying was I couldn't believe the ECU response of the dealer either. They seemed about as clued up as if I'd asked Macdonalds staff.
