Continued Excursion troubles
Due to previous problems (see Excursion power loss on hill in eng911 forum) I borrowed a car, so the excursion is parked for now (except for last night), so I guess this isnt a 911 issue, thats why I move this here.
I took the exc to my father in law's who has an Edge Evolution for his 94/96 ish PS to pull codes trying to find problem. On the way out the driveway, it starts acting up, I was stopped to put on seatbelt, engine starts hunting bad, lurching against the brakes. wierd.
Drive, OD off light now blinking. it goes out after 30 seconds or so. Then the exc. acts fine all the way to father in laws. Plug in the Edge, reads 3 codes:
P0722 No Signal from Output Shaft speed sensor
P0720 insufficient input from output shaft speed sensor
P0503 Vehicle speed sensor intermittant
I had tried to pull the codes with a centech code scanner from harbor freight, it only pulled the 720 code, I used it again and still only pulled the 720. Dont buy the centech scanner from HF.
Anyone seen these before?
I assume I need to replace the speed sensor.
Would the speed sensor being bad cause the problems I've been having?
