1994 Nissan Pathfinder Repair Question
RPM Needle going crazy!!!
You may have fried something in the ECU. Check the wiring to the distributor.
Ok thank you very much!
So if I did fry something what needs to be replaced? The ECU or the Distributor or Both and how will i be able to tell? I'm wondering if it has something to do when I jumped that car?
Most likely the ECU, unfortunately. Pay special attention to loose grounds and connections. There's also a control module under the right front seat. The grey wire there feeds the tach.
Ok thanks again!
My pleasure. Let us know what you find out and tell your friends about us!
Ok sounds good I hope I can figure it out and I always tell my friends how Professional you guys are!
The tach signal comes from a couple of sources. There's a crank position sensor in the distributor, and the negative, or tach side of the coil. Those feed into the control module I mentioned above, which generates the signal to the tach.
Ok I'm not to Mechanically inclined so I'll have to wait for a Buddy of mine to check it out thanks again!
My pleasure. Let us know what you find out.
