adam hrachowina Posted June 21, 2008 Report Share Posted June 21, 2008 Fitted a new icv and was monitoring idle through warm up when an `Aux1 over 5 volt` message popped up,aux 1 is configured as coolant temp and latest firmware is installed, staus bars on screen show ok and coolant temp displays ok ,any reasons for this?

Simon Posted June 26, 2008 Report Share Posted June 26, 2008 This is an indication that the AN1 input has been pulled to 5 volts. Sensor might have gone short circuit. Or what is more likely the input might have lost contact and floated high. I would check sensor and any connections between ECU and sensor.
