Oxygen Sensor fault displayed.
Hi folks, I've got a RR-4 model.
And I was just wondering if anyone has some advice on how to diagnose which oxygen sensor is faulty?
The "FI" is displayed on the lcd panel along with a flashing red light, which displays a two long dashes followed by 3 shorts pulses which according to another thread means fault code 23, oxygen sensor heat element fault. Please note this only happens intermittently.
I understand there is two oxygen sensors 1 for cylinders 1/2 and another for 3/4 and that they are not the same part, therefore if I want to replace it myself I need to be able to detect which one is at fault.
Anybody out there got any ideas?
I was thinking a multimeter could be used to test for resistance on either sensor?
