Hi I pulled the codes off my 1992 Cadillac Deville. The codes were E61, E62, and E65. What do these mean and how do I fix it. Thanks.

It stops on ecm or pcm. Use the low fan button for no and the hi fan button for yes. It stops on e or pcm. Push yes to enter the cpu. Then it will say e or pcm data? Push no again. Then it will say clear e or pcm codes. Push yes to clear the codes. Do this on all the cpus. Then hit auto to get out. Now reenter the cpus and all the codes will be erased if not that code is current drive 10 miles then check it again.

EO61 --- Cruise vent solenoid problem
EO62 --- Cruise vacuum solenoid problem
EO65 --- Cruise servo position sensor signal problem

It appears that all the issues are with the cruise control system.

Pull the small hose of the soleniod on the servo. Vacuum is their. Then pull the large hose off the servo and check the brake light switch. Blow in the hose it should hold vacuum. Then have someone hit the brake. When they hit the brake u can blow though this hose. When they release the brake u cant. Next step would be lift the drive wheel. When it gos over 30 mh set the cruise. It should axcell and u hit the brake to stop it. Shit I used cinder blocks once. Youll need a test light to see if the sel. Is getting the signal form the dash sw. Dont worry about thanking us its our job

Ok so I am back from the mayo clinic and I got good care their. 5 Years of being sick. I will have to go back because the guy is sending me to 3 other doctors. So anyways. I opened the hood on the car and I erased the codes. I checked the codes again and e65 stayed on I looked under the hood and all the hoses were fine. I went to the servo and it was unplugged. I erased the codes and it hasn't popped up again. I took it out and the cruise still does not engage. The light that is suppose to come on doesn't. So I don't know why this will not work.
