Mar 26, 2017. #2. Hi, Welcome to the FF. The 1.8 engine temperature sensor has a 4 pin connector, but only 3 of them are populated. Referring to the diagram below, A1 = Empty, A2 = Red/black. B1 = White, B2 = Orange. Test the resistance of the sensor between pins B1 and B2 with the engine hot and cold. .

Davren said: Only the diesel engines have an oil level sensor, so if this is about the 1.6 petrol engine you've posted about previously, it doesn't have one. Assuming you're referring to the oil pressure warning light, that only comes on when the oil pressure is low.9g1G8. 454 493 235 326 0 219 16 141 274
