How to test coolant sensor wiring is in perfect working order?
Hi all, as titled
How do I test that the wiring going between the engine coolant temperature sensor and the ECU is in perfect working order? I have a basic multimeter, but not one that buzzes for continuity. Any advise greatly appreciated. Thanks, Bolin.

Why not just run diagnostics on the IPK ? It will show the reading from the sensor in real time. That will be a complete system test. Or hook up to T4 diagnostics or an alternative ELM type of thingy. |

I.e. Do I put one lead on one end of the wire in the engine bay and one on the other end at the ECM connector and then expect what reading on the display if all is OK? (And then repeat for the other wire, logically). I assume this approach would be the same for the link lead going to the sensor itself? Lovel - thanks for the suggestion but I was getting nonsensical readings on the OBD, hence needing to test further. I think the problem was air bubbles in the cooling system but ant to check the wiring whilst I have access.

Touching the probes gave a reading of about 0.5 ohm.
On the four bits of wires this increased by roughly 0.1 ohm. All looks OK then.

Yes. Do you have a fault with the temperature readings then?

Yep, probably due to air in the system, currently doing a mini-overhaul of cooling system and then belts & tappets, so hopefully all will be well when finished.
Happy that the wiring has been proven to be OK, I did the test whilst wiggling the wiring as much as possible so am satisfied it is fine, thank you for your help
