Default temp gauge never moves....

hey guys...

I don't mind the rpm gauge being sluggish, but I hate that the temp gauge doesnt work at all!! it makes me so paranoid!

I know about the capacitor that goes bad, but does that make the gauge completely inoperable?

Attached is a picture where the gauge sits all the time...and you can see that even in ACC mode, the rpm gauge is stuck. it does move A LITTLE bit though.

is it a sensor problem or the capacitor problem? thanks!

haha nope... it sits at the exact same place the entire time, whether or not the car is warm.

yea cap problem, replacing them will probably fix ur rpm gauge problem too. but sometimes it is delayed as mine is fixed and sometimes it takes a couple mins for them to operate.

It could just be stuck too. Look for a thread a few weeks ago titled something like "what caps to replace for gas gauge," something like that. A guy replaced a couple caps for that and his gas gauge started to work again. Then the needle got stuck and once he moved it it worked again.

How did you get a red temp needle?
