93 Eldorado Help
Just picked up a sweet 93 Eldorado (w/Northstar) but it needs a little TLC. Currently It has these issues....
On the readout it says to service the airbag and suspension, and the inside of the car smells like exhaust big time while going down the road sometimes and some times stutters when stopped at a red light. Here are the codes it is throwing: R061 = Airbag R062 = Airbag S044 = Lift or dive fault S060 = Left front sensor fault S061 = Right front sensor fault P044 = Right 02 Lean P036 = EGR out of range P030 = ISC RPM out of range P013 = Right 02 not ready P039 = T/C problem Any idea where to start? I really need this car drivable quickly. The emissions part is my number 1 priority right now. I'm wondering if an exhaust leak would cause all those codes to blow. I am smelling exhaust pretty strong at times in the seating area while going down the road. Thanks for the help. |
RE: 93 Eldorado Help
Probably a leaking intake plenum for the lean codes and related to the ISC out of range.Right OXY not ready also because of a vacuum leak. Air bag codes are usually related to a prior collision. ABS sensor faults have to do with the sensors noted in the codes, so check for disconnected, chafed harnesses at the front strut mounting points for the ABS sensor harnesses. T/C problem probably related to a weak torque converter clutch. Usually requires a trans rebuild to fix. EGR code usually refers to cleaning the EGR pipes within the intake manifold of built up carbon. Sounds to me like this cars been wrecked and not put back together completely or properly?? Where to start, get a factory service manual and attack the codes in the order they display.

RE: 93 Eldorado Help
You will need FSM to deal with air bag light.
Check to see if position sensors are there and attached to front lower control arms as carnut suggested. PCM codes take EGR valve off and see if its closed. if its stuck open it could cause multiple codes. You need to learn to use 'on-board' to figure out what wrong. P39 TCC high chance trans repair is required but it could one of the brake switches. |

93 eldorado
I am not a "mechanic" but have successfully repaired several electrical issues on my 93 eldo (I have the 4.9). One thing I notice is any one or all of these codes could be generated by a loose or dirty connection in the wiring harness or where the harness is connected to the ECM. The car is 21 years old and its bound to have loose, dirty, cracked or damaged connections. I always start there. That has saved me from buying uneccessary parts a few times. Who knows, you might find one loose common connection, fix it and your off!
