I figure I'll do a little updating because this seems to be a common part to go.
What started as a blinking trac light which would intermittently come on and off, is leading to a replacement
It was a nice day, figured I’d finally clean that sensor
Gently sprayed the crc MAF cleaner on the exposed sensor, and quick shot into the metal housing
Waited 10 minutes, plugged it all back in and started the car. At first there were more lights on my dash than a Christmas tree
When it finally all settled down, I was left with a rough idling car, with leaps in RPM from 800 – 1700 and the check engine light and trac off lights on, car shifts hard between gears
I’m hoping that swapping out this part will fix things because it is the only part I touched. Also before doing all this make sure you disconnect the battery. That’s what the repair manual says , so I think I will take its advice from now on
The part catalogue says that the part needed is for a 92-95 sc400 is 22250-50030 but that is both the sensor itself and the housing
The sensor which I just pulled is part # 22204-42011 by Fuji electric. This is the same sensor in a ls 400
Which according to Wikipedia the sc400 and thels400 share the same engine so parts should be interchangeable
I don’t have any error codes yet
