The security system (VATS/Passkey) installed on these GM cars is anti-owner more than an anti-theft. There are 3 parts involved:

  1. The chip-key
  2. The lock cylinder
  3. The TDM (aka the brain of the system)
if any of these parts fails or is even slightly malfunctioning, the car stays stuck where you are and you only get a dealer asking you about 1,000$ to fix it. And all the 3 parts have a quite short lifespan. Way too many people got in this situation (including myself). I don't recommend any partial solution or any used parts as it would happen again way too soon to be acceptable and if it happens 100 miles from home (like it happened to me....) it's a big burden. I finally made it to save my beloved 94 Park Avenue (with the exact same system that is installed in your car) with a solution that I found on the internet and that bypasses the entire factory security system, all 3 pieces altogether and you can even remove the TDM at the end and use 99c keys without chip. The product I used is at http://newrockies.com and is still working perfectly after 5 years. Don't go to the dealer!

1994 Cadillac Eldorado Northstar High idle


I am not sure if this will help you but PO27 is listed as "Open Throttle Signal Switch" which could mean that your throttle position sensor needs replacing. Although with Cadillacs, it could mean anything. I hope this helps...
