- Volvo 940 turbo | cooling fan troubleshooting | ecu temp sensor |
My Volvo's cooling fan won't turn on and I have been doing troubleshooting. The fan and relays seems to work but I'm trying to find out what is going on. I really hope the ecu is fine and I justa have a poor ecu temp senser.

nice diagnostics work
Thanks! I hope that new sensor will solve this problem.👍
Great video! I wish you success in your hobby!
Thanks!
Great video!! Helped a lot! I have 95 940 exactly same symptom.. wish I could solve.. I followed all procedures no luck): I really dont know where to check..
In my opinion, this is the only real weak point on the 940 cars - these silly electronic fans and all the stuff they require to run them.
It seems the previous owner found a better solution...to turn on the fan when the water reached a specific temp, rather than relying on the ECU to control it. The sender in the hose also allows you options to choose a value / range to trigger the fan vs. using the stock programming - which also seems to wait way too long to turn on the fan (and the engine tends to run much hotter than it was originally intended).
i have the inverse problem, the fan on my 940 turns on right after i turn on the engine even if the sensor is not connected, ill try checking the resistance of the sensor after i put it on hot water
I hope you can fix the problem.👍 I’ll do a new video when my new sensor arrives.
@@hanssgarage1886 hope it arrives soon and works perfectly
