:confused: I just got done reading the codes on my '94 ETC for the first time, and this is what I came up with:

P032 H- Open MAP Sensor signal
P052 H- PCM Memory Reset
P071 H- Intermittent MAP Signal
P109 H- Keep Alive Memory (KAM) Reset/PCM Has Lost Primary Battery Power

I052 H- Keep Alive Memory (KAM) Error

No ACP Codes :)

No SIR Codes:)

T073 H- PCM-EBTCM/EBCM Pulse Width Modulation Signal Fault

S025 H- Right Rear Damper Solenoid Valve Short to B+
S026 H- Right Rear Damper Solenoid Valve Short to Ground/Open
S027 H- Right Rear Solenoid Open Circuit
S028 H- N/A, Couldn't Find Info :confused:
S072 H- Left Rear Accelerometer Fault

What do these codes mean/are any of them serious? Since they are all history, can they be cleared, and is it OK to continue driving the Caddy? Thank you SOOOOOOOO much, if you can help!!!

If you are not having any drivability problems, I'd clear them since they are historical and see if any return.

That's what I thought to, but since I am VERY inexperienced with the N* system, I figured I better check. Any other opinions??

Oh, something else I forgot to mention. I left my fog lights on, and my battery was dead last night, so I charged the thing, than reset the engine per the instructions on pg. 275 of my Owner's Manual. Could that have anything to do with the codes?

P032 H- Open MAP Sensor signal (You may need a new MAP (Manifold Air Pressure) sensor)
P071 H- Intermittent MAP Signal (Same as above)

P052 H- PCM Memory Reset (From battery dying)
P109 H- Keep Alive Memory (KAM) Reset/PCM Has Lost Primary Battery Power (From battery dying)
I052 H- Keep Alive Memory (KAM) Error (From battery dying)
T073 H- PCM-EBTCM/EBCM Pulse Width Modulation Signal Fault (Might be from battery dying)

S025 H- Right Rear Damper Solenoid Valve Short to B+ (Check the wiring going to the drivers side rear shock)
S026 H- Right Rear Damper Solenoid Valve Short to Ground/Open (Same as above)
S027 H- Right Rear Solenoid Open Circuit (Same as above)
S028 H- RR Damper Solenoid Short Across Load (Same as above)


S072 H- Left Rear Accelerometer Fault (Refer to this thread: http://www.cadillacforums.com/forums/suspension-brakes-tires/56391-check-out.html )


You probably just turned the car on and immediately checked the codes, that's why they were all "history". You didn't go for a drive to give them a chance to become current during that particular ignition cycle.

A dead or weak battery can wreak havoc with these systems. Now for sure I would clear them and see if they return.

How do I tell if I need a new MAP sensor? Thank you, everybody, for all your help!

First clear it and see if it comes back after a drive.
