I was driving today with the ODB-II adapter connected so that I could see the data in my mobile. I could see that although the temperature gauge was pointed at 100 degrees (celsius), which is where it normally is when driving, the PCM value was 90 degrees. It seems that with the new temperature sender (which I put in as part of the job of changing the LIM gasket) the gauge is indicating a higher temperature. I had noticed before it was indicating a higher temperature when the thermostat opens than earlier. Probably the PCM reading is the correct temperature as it corresponds to when the thermostat should be opening. Either way it's the PCM's temperture reading that controls when the fans are starting.

The guage on the dash is just an idiot light with a needle...... not calibrated.......
