Clutch temp light

[TS2022]

Yep. Shared ground going to the sensor and other wire, only 2 to it, goes to ecu. Sensor trips and passes the ground to ecu to trigger the light. Sensor mechanically trips at a set temp to complete the circuit. Common sensor for temp lights and fan control. Already swapped to a known good one so should eliminate the sensor.

Sorry have been away for awhile, but yes replaced the sensor with a known good one. Shot the case where the sensor was with a thermo gun an was not over heating. Was maybe around 165 or so.

Cleaned oil cooler just incase, but it had no blockages or any problems.

I would think it would be a ground but it only does it on hard acceleration. Can run it around all day normal no problem.

There isn't any new sensors in the engine/trans on a Talon that aren't in the Pioneer.

From what I've gathered Honda is using the Oil temp sensor in the clutch cover to monitor oil temp and trigger the PCM to turn the clutch "overheat" light on. They didn't add any additional sensors for that function is what I'm getting at.

Wee were talking to another dealership who was trying to run KOH this year with a fresh engine build having this same issue. As far as I know they hadn't resolved, atleast not since I last spoke to them.

That sensor uses the dame ground for all 3 Oil Pressure sensors in the clutch cover as well. I'm beginning to wonder if it's not a ground issue, I believe OP replaced the sensor already so it rules that out. I'm wondering what the sensor is reading and if it really is hot or just reading hot. Since unplugging temperature sensors usually causes high volatge and fans to turn on when used in the cooling system.

If you unplug thay sensor, does the light stay on?

Honda tech I have no tried the unplugging the light to see, but I can try that tomorrow
