i believe it comes from a crank/ or cam sensor.... idr which though... but i think crank cuz i think the cam sensor adjusts when the coils fire for timing and the crank for rpm

 

The crank sensor tells the ECM where each piston is in relation to one engine revolution but it cannot tell if any piston is in a compression or exhaust stroke. The cam sensor tells the ECM whether each piston is in a compression or exhaust stroke.

 

Thank you so much guys. I was racking my mind and couldn't think of it. Just to confirm I went to alldata and confirmed with the following.


The crankshaft position sensor, consisted of a magnet and coil, is located next to flywheel. The voltage signal from this crankshaft position sensor is relayed to the ECM to indicate engine RPM and the position of the crankshaft.

 

rocconi its a little more complex then that....

 

It seems like it just got a little more complicated. My sensor is good and the wiring is good as well. Any ideas on why I would still not have my tachometer working?

 

does it go on and off???... umm this sounds crazy BUT... push on the plastic toward the tach... if it comes on idk whats wrong with it.. cuz mine does it to... mine goes on and off and if u push on the cluster plastic casing it comes on....

 

Mine doesn't come on at all. Off all the time. I wonder if it's a loose wire behind the cluster, in the plug itself. Worth checking out I guess.

 

if its the stock tach it could be the cluster as well. a short from screwing the front end...but yes check your wiring first.

 

hey zero.. dont u got a crankposition sensor in ur asshole

 

yeah it tells me when i need to poop so i can come over and **** all over your crappy DSM

 

hey dont talk **** about her
