Hello,

I have a 2002 Deville with 106,000 miles on it. For the past few months it has been doing this - At speed on the highway, the car will "bounce"...It's like it stalls and then restarts (itself) in less than one second. It usually does this 5 - 10 minutes after it has been started and then it doesn't happen again until the next time I drive it. If you are going at a low speed (< 40) it will completely stall, then you have to recrank it with the key. Also, since last Friday when I had it detailed, now I'm getting a "Service Security" message in the dash as well. Does anyone have any ideas about these issues?

Thanks!

Might be a bad CKP sensor.Common problem on the 2000 - 2003. GM had a bad supplier. Pull the DTC's. It may have set a code, though they don't always seem to.

Here are my codes -
IPM - Instrument Panel Integration Module
B0429 - Temperature Control #3 Rear Circuit Range/Performance (current)
B1004 - Keep Alive Memory (KAM) (history)
PCM - Powertrain Control Module
P0385 - Crankshaft Position (CKP) Sensor B Circuit (history)
P0463 - Fuel Level Sensor Circuit High Voltage (history)
RFA - Remote Function Actuation
B1327 - Vehicle system voltage below 9.0 volts (history)
VTD - Vehicle Theft Deterent
B3055 - Key Not Present (History)

Looks like the CKP is the issue, correct?

P0335/6 and P0385/6 are CKP's. Look at www.rockauto.com or call Luke in parts at Lindsay Cadillac, over there --------->

You can also look at www.gmotors.com (Palm Chevrolet/Cadillac in Gainesville, FL) and www.gmpartsdirect.com (Flow Chevrolet/Cadillac, Winston-Salem, NC)

The faulty series of 2000-2003 CKP's were made by Siemens in Mexico. The new series is Japanese. If you replace both sensors (recommended) you MAY get a driveability problem due to slightly different timing signals. You then will need to have a dealer perform a "CKP Relearn procedure". It'll cost you a half-hour of labor charge. The actual replacement is straightforward, but close quarters, and you really need the car up on a lift. The individual electrical connectors require magic words.

OK, thanks for the help!
Any other issues from those codes that I should be concerned about? My "Service Theft System" light started coming on last Friday.....

Maybe the detailer played the sound system and ran the battery down. The radio is interlocked with the vehicle theft system, so if the radio had/has a hiccup, that may be it.

If you live in an emissions test state, DO NOT clear the codes within 2 or 3 weeks of a test. The system needs to settle after a reset and it will give the test station set a "Not ready" signal, you'll fail, and then have to come back later on.......Start a log, say every 3 weeks. If a fault does not exist for 3 ignition-start-run-stop cycles it goes to H, and if it does not occur in 40 cycles, the fault and code self-clear.

As you become familiar with the code reading sequence in your 2002 with 3-button control, try this: When the DIC asks "All Codes" answer "No". The DIC will then ask "Axx" (module name), answer "Yes". You can then look at each module at your leisure by simply answering the correct "Yes/No" to each module request, and you can go back to a module with the rocker switch. Turn the ignition OFF at any time to exit.

B0429: The actuator just left of the glove box which controls air to the rear console panel is OOC. PITA

Be sure to replace both A & B sensors while you are in there. The other will surely fail soon.

Wow I did not know about the CKP relearn at the dealer, that definitely explains my random shutter at idle when warming up my car here and there every few days or so, I did change both sensors but could never figure what the shutter was, im really debating getting one of those aftermarket warranty's and dropping the car off at the dealer for a good week this thing needs tcc solenoid, big 2-3qt oil leak an oil change, and steering rack all big $$ items.

Sorry hi-jackin this thread, anyways thanks a lot for the CKP re-learn tip, this is why i am on this forum.
