Re: 2015 Yukon XL temp gauge at 0 and radiator fan running constantly
If the fan running for 15 minutes killed your battery multiple times, then it was already on its way out.

Any updates on this?? Our truck is doing the EXACT same thing. We've replaced the sensor 2 times already. It'll work intermittently.

Quit buying junk sensors. If you read the thread the last post about the sensor said it was good to go.

Re: 2015 Yukon XL temp gauge at 0 and radiator fan running constantly
I Got this issue with 2015 GMC yukon, the first sensor i got is autozone brand which failed after one month, second one i bought from GMC dealer which failed after 3 days, i am suspecting it could be a faulty ECM, i am doing the scope test tomorrow to confirm if its ECM or the wires.

Re: 2015 Yukon XL temp gauge at 0 and radiator fan running constantly
I am very interested in following this. I have a 2015 Yukon XL and have replaced the TCS three times.
It is intermittent. Will run for a few weeks and then the temp goes to 0 and fan runs. Then it will go another week. Seems like it happens more when driving on surface streets. Can the wiring harness be replaced without removing an entire harness? Where can I check the resistance up the line further. Someone mentioned the ECM, where is that at? Just real frustrated I can't fix this! |
