Tachometer doesn't work

My tachometer on my 2005 tacoma is not reading anything but every other one works ? Any ideas I need help!

 

I would start by checking fuses. On the old 80's toyota's the tach and the speedometer were on seperate fuses. I know a lot has changed since then, but its a good place to start.

 

Doesn't move at all or points in the wrong direction? My mustang's tach pointed wherever it damn well pleased. Fix was a cheap stepper motor purchased on eBay.

 

(4) RPM signal circuit
The camshaft position is detected by the VVT sensor LH and RH, and is input into TERMINALS VV1+ and VV2+ of the engine control module as a control signal. Also, the engine RPM is detected by the crankshaft position sensor and the signal is input into TERMINAL NE+ of the engine control module.

The ECU sends the RPM Signal to the Combination meter via the Black wire with a white stripe.

 

Would you know where to find said fuse?

 

It doesn't move at all I just stays at 0

 

I also installed my 40 inch led bar and grounded it near where the negative terminal from the battery grounds out. Would this affect anything?

 

Jimmy gives a pretty good suggestion in this thread. There isn't much on here on this subject really. I hope you find it.

Thanks for the thread!! I'm going to try the scan tool nd thanks jimmy!!

 

There is no fuse for just the Tachometer.

 

No effect. A ground is a ground.

 

Shit I forgot about posting that... Good find.

OP let us know what you find.

 

I will but it works sometimes and there is a strange buzz when I turn on

 

It all started when i tried wiring it

 

A good rule to follow in these cases.

It was working fine.
I did X, Y or Z and now it doesn't work anymore.


Undo what ever it was you did, all of it.

99% of the time that will fix the issue. The other 1% is other causes or it was damaged.

 

Took it off now it just works when it wants

 

Did you try a scan tool?

 

My brother is going to try it he goes to UTI see if he tries it

 

Any fixes for this issue?

 

Mine ended up being the 4wd fuse on my 96 3.4L
