I am getting a code of 1860 on my 2000 Eldorado. Trany was replaced about 60,000 miles ago. Any info would be
appreciated. The only indication that I have a problem is my "service engine soon" light is on. Car runs fine....
problem or not?
TCC PWM solenoid electrical. P 1860. Either the main transmission cable connector is dirty/wet (under the lower front of the transmission, curls up and around the top) or the solenoid itself is faulty - and that's a $50 part buried $2000 in labor inside the transmission if you're not a technical DIY person with surgery skills.
That's an emissions failure fault.
Google "cadillac forums p 1860 solenoid replacement".
Well let hope it is just dirty and wet otherwise I will drive it until it refuses to go.... I have already replaced the oil pan gasket, manifold gasket, crank sensors, bank 1 on the plugs, like I said before I think they self destruct..... I refuse to put any more money into this car and it is a beauty! Thanks, Submariner409 I know you have helped me in the past.....
It's not in the manual - use the sticky post just above this thread......... the "How to pull codes". When you finish scrolling through all the modules and their codes you'll be asked "Clear all codes ?" Use the proper button/rocker to answer "Yes".
Soooooo ............. to keep the light out I think you have to do the whole code thingy each time you start the car - I don't believe Eldorado ever got the 2000 and later DIC controls of the Seville/Deville - except for the engine most of the rest of the car is a 1998.
