Max, not heat related. It does it cold or hot. I think the contacts in the connect just arent making good connections. I tweaked the pins on the sensor and that changed it a little. I went into the connector and tweaked the contact pads and that helped more. I used a meter on the cable to and end to end check and look for cracks in the wires and couldnt find anything. So it looks like the connecter is the issue. The pins on the sensor are quite thin compared to the connector and that probably dosent help.
