Man... I just had an oil service not long ago, and then yesterday, warning light came on while driving and turned out to the bad oil temp sensor.. I haven't check for loose wire yet as I have no way of getting under the car but doubt that's the case. And in order to replace the oil temp sensor, pretty sure the oil needs to be drained? But the oil is like maybe 2,000km old, really not sure if I should replace the sensor now, or live with the warning light till the next oil service... What would you guys do?
