Problem:
Speedo intermittently reads high (10-20mph) but then after a shutdown may return to normal.
Generally on start, it will be at zero mph and follow speed as normal. But at times on start it may be at 10mph parked and follow 10 over and back consistently with speed increase and slowdown.
I am thinking it is the Output Shaft Sensor...????
But what is the part number on the OSS sensor?
Cant find anything that tells me the Ford P/n or conclusive diagrams that say it is Motorcraft p/n or anything consistant.
Anyone got a trany out that can read the p/n?
Or know for sure what it is?
