Tachometer

[mho]

Tachometer stopped working, stays at below 0 where it normally is when the car is turned off..

any ideas where the tach sensor is?

mho,

I have a '92 LS400, and the tach never worked since I first got it. The tach gets its signal from the igniters under the hood and easily accessible. Your problem, however, like multitudes of other LS400s on this forum, may be the meter itself - seems like someone suggested there is gummed up oil making the needle stick to its limiter(?) In some threads on the Supra forum, however, I saw something that seemed to indicate that Toyota skimped on the solder used on the circuit boards, and so over time the connections break. Haven't had an opportunity to take my dash apart yet, but would be mighty interested in knowing what you find out.
