As i dont have a T300 to check for error codes, is there a way of checking temp sensors and o2 sensor for propper working order?
For the coolant temperature sensor, if I remember correctly, if your fans are working ok, disconnecting the coolant temperature sensor should turn on the fans. The sensor changes its resistance with temperature change so you can use a digital multi-meter to determine its resistance with temperature change. For the oxygen sensor, you need an oscilloscope or a digital multimeter (don't use an anologue multi-meter as it will cause damage to the sensor and, possibly, the ECU).
