I'm really hoping someone can help me out. My 2005 DeVille stalls when water hits a certain way/part underneath the hood. It has happened during a car wash, at the beginning of the one that has the tracks that pull you through. A few months ago I was driving on the highway in a rainstorm and was straddling the water in the ruts, closer to the shoulder, and a car pulled over on the shoulder. So I went to move over and the force of the rain and the water from the ruts stalled my car. I didn't have control over steering or anything, had to get it in neutral, turn key off, then on and then get back in drive and move the wheel. It was so scary as I was meeting vehicles, horns were blaring and due to the storm, it was difficult to see anyway. Today, I went through a deep puddle and it happened again. Has this happened to anyone? What is causing this? I did have the car in to a mechanic after that near death experience on the highway but they couldn't find anything wrong. Today after it stalled from the puddle I called OnStar immediately for a diagnostic but they couldn't tell anything had happened. Thanks! Tammy

Hiya !!! Welcome to the Funny farm !!!!

These cars have a large diagnostics system which sets codes when bad stuff happens. Those codes can be stored for a LONG time, so - two chances here -

IF your 2005 still has the owner-operated diagnostics system, study the proper model/year parts of the sticky post on the Deville main threads page - "How to pull codes". Practice, write down any found codes and go back to the sticky to open the link to definitions of all OBD-II codes. Decipher your codes and post it all here.

OR, if you don't have owner-operated diagnostics, take the car (dry weather :rolleyes:) to a large auto parts/accessories store. Ask them to scan the car for you.

Oddball stalls and hiccups set trouble codes that point (hopefully) to problems. BUT your problem is a new one.

I have heard of this before, but not very often. Probably irrelevant, but is the lower air deflector (#16) in place?

Hi! Thanks for responding so quickly. I did figure out how to get the codes and here is what came up - I've added what I can find they mean.

AMP B1004 history - KEEP ALIVE MEMORY (KAM)
AMP B1327 history - DEVICE POWER CIRCUIT LOW
U1000 current - CLASS 2 COMMUNICATION MALFUNCTION
U1128 history - LOSS OF COMMUNICATION WITH IRC
U1016 history - LOSS OF CLASS 2 COMMUNICATION WITH VCM
(I think those last 3 started with AMP)
IPM B0429 current - TEMPERATURE CONTROL #3 REAR CIRCUIT RANGE/PERFOMANCE
IPM B1004 history - KAM??
RIM C0625 current - LEFT REAR SENSOR MALFUNCTION
RIM U1160 history - LOSS OF COMMUNICATION WITH DDM
RIM U1161 history - LOSS OF PASS DOOR MODULE SBI
RIM U1163 history - LOSS OF REAR PASS DOOR MODULE SBI
RIM U1162 history - LOSS OF REAR DRIVER DOOR MODULE SBI
VTD B3055 history - KEY NOT PRESENT

There were no codes for the following: ABS, DDM, DDS, DIM, IPC, IRC, LRD, MSM, PCM, PDM, RRC, RFA, RRD AND SOM.

Does this help? Or do I need to google more definitions for the current and history codes?

Thanks! Tammy

----------

I have no idea, but tomorrow I can see if that is something I can find. I am not mechanically inclined at all, I shocked myself at being able to find the codes!

Hi Ranger,

The lower air deflector is in place. Any other suggestions? Do you remember what caused this for other people? Since I think you, my husband and I are the only ones that have heard of this before!

Thanks, Tammy

Nah, it is so rare I don't recall what it was or if we ever figured it out. It is not normal or common, I can tell you that much.

Can't imagine what could get wet that may cause it to stall.

On second thought, the CKP sensors are down there. Might check to be sure the connectors are on tight.

Thank you Ranger! I will bring it to a mechanic and have them check that out. I'll let you know what I find out. Thanks again :)

Mystery solved!!

I took the car into a Mechanic and told them what was happening and provided the upper and lower crankshaft sensors to be changed. They called me back after 2 hours of doing a diagnostic and apparently the harness that holds all the wires was burnt so badly that he described it as crispy and if it wasn't crispy it was melted. So they traced back to what wiring they could use, ordered 3 pigtails (2 to the crank sensors & 1 to the oil pressure sensor) and connected it all properly, and replaced both crankshaft sensors. Said it was highly recommended to change the sensors as they had been getting intermittent surges and didn't want to reuse the old ones.

Ranger - I can't thank you enough for all your assistance and advice, greatly appreciated.

Now I'm onto researching for a rear leveling sensor....apparently GM discontinued them!

Again, thanks so much!!
Tammy

Glad you have it fixed. Never would have figured that one out from here. Never heard of this one before. Did he say exactly where this crispy harness was? I'm curious as to what burned it and why.

They just told me that somehow it got too close to the exhaust and as soon as the mechanic touched it, it fell onto his face. This is what I took from his explanation - the harness is made up of (or has) 3 pigtails; 2 to the crank sensors and 1 to the oil pressure sensor and it runs near the exhaust. Somehow mine was way too close to the exhaust and was either burnt or melted. They routed it properly and put extra heat shield on the wires just to be extra safe.
