Greetings from Zagreb, neighbour :)

Focus MK1 has servo motor attached to the cable. at elast the euro version !!
You do not have throttle position sensor, you have ordinary cable from the pedal to the throttle valve and servo motor on it for cruise control. F' yeah :)

sailor Can't guess on that one, how does the car respond when holding the pedal at that speed manually?

Will it hold that speed on a flat road without pedal movement? Or are adjustments needed to keep the speed even.

kisdnl Hello,

I have got a problem with my cruise control.
It work, hold the speed, accelerate, decelerate, etc..
But when the speed about 130 km/h, the gas pedal begin a periodic motion.
It is a little motion, but I feel in the car movement, a little annoying on a long road.

What is the possible problem?

Ford Focus MK1 (1.8 Zetec)

Thanks,

IrocZX3 Mine works intermittently. And strangely enough seems temperature dependent. Cruise will work ALMOST all spring and summer but will not come on below say 45°ish. I was originally thinking a pedal position sensor was sticking in the cold... now not sure. Gonna give this self diagnostic a try.

CarGuyNeil So after the delay from Amazon on the switch I went to install it and found the original was just out of its hold down so just loose in the socket. Once repositioned it worked fine and my cruise control is functional again. And I have a new spare cruise control deactivation switch. I couldn't have done it without this thread. Thanks to the OP!!!!!

CarGuyNeil I ordered from Amazon Prime to save on shipping and because they claimed to have it in stock. That was December 28th...still hasn't shipped. A little frustrating to say the least. Usually Amazon gives better service. Granted this isn't keeping me from driving the car, just disappointed with the time frame involved, plus I want to see if this fixes it.

CarGuyNeil I got the test to work and got 3 flashes for brake deactivation switch. Does anyone know if Motorcraft SW-5576 is correct for an 04 SVTF?

erbonetti Well I didn't realize the upper center brake light wasn't lighting, so I'm guessing that's my issue, becuase I pulled on the cable, and it appears to be connected just fine. I just bought new bulbs for the brake light, but its still not lighting. the wiring to it appears to be fine, but I'm no electrician. Should I replace the wiring harness? I really don't know what im doing with electrical work ugh.
