Hi,

To my knowledge, error code 41 on a 1990 Cadillac Deville indicates "Camshaft Position Sensor (CPS)". Procedures on how to check, remove, replace, re-install the CPS is outline here with illustrations.

On the otherhand, error code E53 indicates possible fault at the "Distributor Signal Interrupt". You may want to reference this for additional insight/information.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    battery cable failure - an intermedent open in one of the cables.

    Clean the cable attachments. Retighten them down securely. See if you can get to the ground cable where it grounds to the motor (usually) and see that this ground is clean and tight. Look closely at the cable ends at the battery. Acid could have gotten down inside the cables, under the insulation, and literally eatten the cables apart. it shud be an electrical problem
    Have a nice day!

    If it is not an engine problem, it should be a problem with the
    transmission. When the gearshift is in drive, in this case, the gears
    get jammed with each other, causing the whole engine/drive train to lock
    up, stalling the engine.

  • dewan nafees ahmed Jun 14, 2008

    if its the camshaft sensor as per benimur
    then u can find the cam shaft in the head closest to the firewall, in the front
    located on the side of the cylinder head/valve cover,near firewall,on passenger side.

I have a Isuzu i290 what would make it turn off as I come to a stop


wow , no year car stated, . there. and seems engine related.
the engine is
i-290 - 2.9 L Atlas LLV I4a very rare car and very poor sales (also called Vortec 2900) engine. Gas MPI injected.

this is called engine stall. right?
im not arguing words, we are being clear.
Turns off has vast connotations.
the car is full of electrics, and EFI and all can turn off. (fail) (engine off, 12vdc power turned off?(fuses and other reasons)

and the engine can stall, it goes to 0 RPM and that is stalled.
the engine is not running. stalled.
so if engine stalls , there are 50 causes.
we don't guess, we do the 1 to 10 tests using TOOLS.
and find what is bad.
ill now list top causes , not wild guessing.
1: never had a tune this decade wins hands down cause.
(operator error oldest story for 100 years now....)
2: lost engine compression/ lost.
3: spark lost (skip of diesel)
4: fueling bad, too much it floods and stalls , too little it starves.
5: lost electrical power to critical EFI systems.... dead car main battery? fuses blown
6: EGR valve stuck open.
7: ISC valve stuck closed.
leaking injectors, or clogged, or? weak?
lots more, and tests. wana learn the tests???????


each has simple test and cheap tool.
any good mech that can witness the stall can tell you while driving it why.
(dash lights , tell you)
right foot, fails to prevent stall.
violent shaking of engine , misfiring
or if adding right foot action, allows you to very easy prevent the stall, implies the ISC is stuck. now you know why hands on testing wins and asking us, blind net bunnies don't . work well...
sorry, but is true.

Stalling when turn back on


all stalls end in CEL check engine light on. that is normal
but CEL glow. when engine running , means you had a failure, and it stored DTC error codes, so scan it.
lots of causes. huge list.
get a tune up , tops list.

SCAN it to be sure all sensors work. running.
all fuses in car good.
by stalls , i assume the engine stalls and engine RPM is 0 RPM.
the stall cause the whole dash to light up, all the warning lamps come
on (self test) oil , charge , CEL. come on.
what is important is the stall and the cause.

i will tell you the 3 ways.
lost electrical power to engine EFI system (seems not)
bad engine, (lost compression hot)?
bad spark , spark died.?
bad fueling, lost all fueling (starves and stalls or floods and misfires horribly and stalls (black spark plug tips are big time clue)

if non eof the rings a bell.?
get the car serviced.

this car is newer nicer car, you (we) can scan and drive and log data.
allowing faster easy diagnosis.

Shuts off while driving


stalls. ? all the time, only cold , only hot engine?
what year car?

can you save it with a fast right foot.?
stalls can be caused by about 50 things, I have a list...
but we dont guess, we do tests and diagnosis this.
it can be one of these.
1: bad engine. (loses compression only hot?)
2: bad spark, ever tune it up? new spark plugs, etc?
3: bad fueling. (too little =starve, too much = flooding)
4: lost electrical power to the EFI system.
5: bad fuel.

Possible Service Engine Soon Light, Engine Stalling, or Hard Starting

Engine, May 18, 2009

RepairPal Expert Overview:
The RTV seal on the fuel system control modules may allow water to enter into the module. Water in the module can cause a short, which may cause hard starting, a crank-no start condition, or stalling, and the Service Engine Soon light may come on. If the engine stalls unexpectedly, there is an increased risk of a crash. Dealers will replace the fuel system control module free of charge. The recall began on May 18, 2009.

Engine stalls, check engine light, not fuel filter.


the white smoke as it stalls could be steam in the exhaust. This is caused by coolant leaking into cylinders from a leaking head gasket. You should check cylinder compression next with a compression tester.

Where is the fuel filter on a Saturn Vue 2004?


It is part of the fuel pump module inside the fuel tank, all the cars are starting to use this type of setup, the filter is only serviced when the fuel pump fails.
