Why does my rpm not work?


Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM). The IPC receives a serial data message from the body control module (BCM) indicating the engine speed. The tachometer will default to 0 RPM if:
?€¢
The ECM detects a malfunction in the engine speed sensor circuit.


?€¢
The IPC detects a loss of serial data communication from the BCM.

97 cavalier 2.2L OHV, MT ; I trying to install an aftermarket tachometer. Distributorless, two coils mounted, stacked on back side of block. No pos or neg wires to this style of ignition coils. I have...


Who manufactured the tach? Maybe they have a web site and instructions? Did you tach come with instructions?

I looked at autometer instructions for your vehicle, have to use an adapter, it ties into the power wire for your coil pack. The adapter costs about 97 bucks, not including tax.

Different tach manufacturers may have different hook-ups?

I have a 2003 spyder eclipse gts 3.0l how do i install a after market tachometer?


I really cannot tell you how to do that. You need to follow the instructions that came with the tachometer.

Please note: I would be very cautious about connecting aftermarket equipment into your computer input or output circuits. These things have been known to cause all kinds of drivability problems as well as make it impossible to pass an emissions test (if it is required where you live).

I have personally seen aftermarket add-on equipment cause everything from engine cylinder misfires to transmission shifting problems to engine stalling and no-starts. I do not recommend using any at all. However, there are usually no problems created by "stand alone" accessories that are powered directly from the battery and do not require splicing into any of the computer circuits.

My professional recommendation on this is that if you think you need a tachometer to operate your vehicle, or you just like the looks of a tachometer bouncing up and down, then you would be money and headaches ahead to buy a vehicle that is equipped with a tachometer from the manufacturer - you may be opening a can of worms that you do not want.

This is just my opinion based on 37 years of experience diagnosing and repairing automobiles (and having to clean-up aftermarket add-on messes) - do with it as you wish.

Rpm needle flutuates when driving


If it is an aftermarket tachometer then you may have to install the resistor that came with it. If it didn't come with a resistor ask an auto-electrician about it, they should know. If it is a factory tachometer you may also be able to try and install the resistor onto coil wire at the back of the tachometer. if you haven't got experience in this area i would suggest you find someone who does.

Fuse for instruments, 10 amp keeps blowing speedometer and rpm gauge don't work changed fuse it just went right away


It sounds like there is an aftermarket(not stock) radio wired in. If the wrong wires were used for the face illumination, it will do this.

I need to know where to wire the green wire to read RPM's for an aftermarket tachometer install on a 1999 chevy s10 with a 2.2l 4cyl.


It is usually to the positive side of the coil - also depends on what type of distributor cap you have, if there is a 3-4 wire plug that goes to the cap, one of them should be marked TACH

its really easy im not to familiar with that vehicle but it all works the same if it hasd a distributer and a seperate coil or even a dis cap mounted coil either way there is two wires that run into that actual coil all you have to do is tap into them and figure out which way works just pull back the unsulation on the two wires that your tac will come with there might be 3 but one will be a ground and just kinda half way hook it up till you see the tac come to life its really easy just be patient and dont worry if the wires are wrong it wont blow anything up the tac just wont work until you hook it up right 9 times out of 10 when you buy a tach it comes with directions
