Cadillac 1994 STS 4.6L hight coolant temperature too fast

Recommended Posts

Hi. I have a Cadillac STS 1994 4.6L with the following list of codes:

P030, P052, P053, P076, P089, P091, P095, P097, P109, P137, S010, S012, S036, S044, S060, S061, S063.

I have a problem with the coolant temperature. It goes up too fast and doesn't stop till 125°C limit and then the car stops automatically. It began when I got the car to a motor wash service. What can it be the problem? Kind Regards, Carlos Blancarte.--

P030 (E030) ISC RPM out of range
P052 (E052) PCM Memory Reset
P053 (E053) Distributor Signal Interrupt

P109 (E109) Keep Alive Memory (KAM) Reset/PCM has lost primary battery power

S036 Electronic Level Control Compressor Short to Ground/Open
S044 Lift or Dive Signal Fault
S060 Left Front Position Sensor Fault
S061 Right Front Position Sensor Fault
S063 Right Rear Position Sensor Fault

This looks like a bunch of codes you would get after power-washing under the hood or under the car. I would let the car dry out, clear the codes and see what comes back. The overheating problem is probably because of a problem with the fans.
