'05 tach problems

my tach keeps jumpin to 3 grand... somtimes 4 and stays there as if its at zero. but then it revs to over 5 and hits the boost guage. it does nothing as far as the engines performance, just ticks me off. the only way i have found to correct it is to pull the instrument panel fuse, but it will only correct it for a while. has anyone else had this problem?

Re: '05 tach problems

Welcome to the site.

I read in power stroke registry there was a tsb # 06-7-4 which says '06 model but it may include yours, an erratic speedometer and or tachometer indicator issues. You may want the dealer to check it out it may end up needing a new instrument cluster. [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Re: '05 tach problems

your '05 is still under warrantie. why not take it in and let your dealer figure it out at Fords cost.

Re: '05 tach problems

I had the same thing on mine. Take it in and they will get you a different cluster. About a 30 minute change out once they get the new one in. Don't be surprised if they want to keep the truck till the new part is overnighted in. They do not want you putting extra miles on while the new part is coming. Mileage is factory programmed and can not be changed at the dealership.

Re: '05 tach problems

My cluster is on back order. They gave me my truck back after two weeks. Now I wait till it is off back order and they get to keep it again. It's a known issue and they know how to fix it. Take it to the dealer.

If you end up on back order like me...you can get the tach to work again by runnning the instrument panel self test. The first test sweeps the gauges. I run that three or four times and the tach seems to settle down to zero again. It works for a few days before I have to do it again. Sometimes the Speedomoeter does the same thing.

If you don't end up on back order for the new cluster I want to know about this. I've been told by some on this forum that the parts are available and my dealer is trying to dick me over.

Re: '05 tach problems

i bought the truck with 77,000 kms on it, this problem happened a week after i bought it. when i phoned the dealership that which i bought it from, they told me thats its off warranty and sorry for my luck, and the used truck manager told me, that he wished he had a crystal ball to tell him everything that would go wrong with trucks..... kinda got the feeling thats happy that he got my money, but doesnt really want to help me out. and now after only 6,000 kms i seem to have a problem with the posi rearend, and have been told that ford has a problem with these.... i tell ya, this truck has put a bad taste in my mouth for fords.... thinkin i should have went against my better judgement and went with *ahem* dodge
