Trouble-shooting: Nominal Value: Cause of Trouble:
Ignition OFF
· Remove oil temperature sensor plug P 24 0 °C/32 °F=3150 W · Oil temperature sensor defective and check resistance at oil temperature 10 °C/50 °F=2200 W sensor P 24 with Multimeter 20 °C/68 °F=1210 W MKM-587-A. 30 °C/86 °F= 832 W 40 °C/104 °F= 585 W 50 °C/122 °F= 419 W 60 °C/140 °F= 307 W 70 °C/158 °F= 228 W 80 °C/176 °F= 169 W 90 °C/194 °F= 127 W 100 °C/212 °F= 98 W
Alternative measurement:
· Make connection between oil 0 °C/32 °F= 4.57 V · Oil temperature sensor defective temperature sensor plug and 10 °C/50 °F= 4.41 V the sensor itself with adapter 20 °C/68 °F= 3.95 V leads from Electronic Kit KM-609 30 °C/86 °F= 3.59 V and connect Multimeter MKM-587-A. 40 °C/104 °F= 3.20 V 50 °C/122 °F= 2.77 V Ignition ON 60 °C/140 °F= 2.38 V 70 °C/158 °F= 2.01 V The voltage value of TECH 1 is 80 °C/176 °F= 1.66 V to be compared with the measurement 90 °C/194 °F= 1.37 V value of the Multimeter at the 100 °C/212 °F= 1.11 V respective temperature
