Subject: there are in total 5 temp sensors for the IHKA Author: shogun (moderator) : member since March, 2004 : 12553 posts Posted on: 2007-10-16 00:44:51

There are five temperature sensors in the system.

1. Passengerside heatercore temperature sensor
2. Driverside heatercore temperature sensor
3. Controlpannel temperature sensor
4. Evaporator temperature sensor
5. Outside temperature sensor

This does not inlcude the temp sensor in the front grill, which has no relation to the IHKA system and only is connected to the OBC.

Sometimes cleaning them all helps for a good reacting heating and cooling system.
