Hello all,


I have a problem. The (service engine soon) light comes on although mine does it internittently. I have a 93 Eldo with the northstar. It has 90,000 miles and all of a sudden I have the "service ride control" light coming on also. I did the diagnostics and here is what I came up with but I don't know what they mean.

PO 13 Right oxygen sensor not ready
PO 42 Left oxygen sensor lean
PO 44 Right oxygen sensor lean

No IPC
No ACP
No SIR
No TCS

SO 11 Left front damper short to B+
SO 16 Right front damper short to B+
SO 21 Left rear damper solenoid valve short to ground (open)
SO 26 Right rear damper solenoid valve short to ground (open)
SO 30 ??

These are all "History codes"

Any help would be greatly appreciated.

Ron

P042 & 44 would lead me to think vacuum leak. P013 might be a bad sensor, but check or a vacuum leak before replaceing it. If they are all history, clear them and see if they return.
