Testing 4-Pole Coolant Temperature Sensor (B11/2)

M) Testing 4-pole coolant temperature sensor (B11/2)





With two ground terminals, engine ground and CIS-E control unit ground, as well as one terminal for the temperature signals for CIS-E control unit and ignition control unit. The resistances of the characteristics are identical to the two-pin temperature sensor (B11/2).

Temperature sensor and connector are designed (temperature signals crosswise) in such a way that the connector can be fitted in any desired position.

Note: When testing the coolant temperature sensor, the resistances should be measured and compared 2 x crosswise (refer to ill.).
