Whatever is causing the timing adjust itself at the wrong time. It could be anything from a vacuum leak, to a coolant sensor to electrical problem. By reading all the LIVE READINGS from the sensors & getting an emissions reading will help u narrow down the problem. It doesn't sound like a DIY fix. Equipment needed

P0174 System Too Lean (Bank #2)
P0171 System Too Lean (Bank #1)

System to lean means that a fuel injector or injectors may be plugged up, or the oxygen sensor is sensing too lean of a condition.

How many miles do you have on this engine?
Have the O2 sensors ever been changed?

When was the last time you had a tune up?

I've changed all the fuses, relays,and the starter on my 2002 Deville dhs and it still won't start.


It won't crank over ? Is there a SECURITY light lit on the instrument cluster .
In the under hood fuse / relay box is the start 1 relay , this relay is energized by the PCM - powertrain control module ! This is the relay that controls the starter ! If there is a anti-theft system problem the PCM will not energize the start 1 relay completing the circuit turning on the starter ! . If you knew how you could test right from the start 1 relay socket in the fuse box , rather that just replacing parts ! You can test with a DVOM -digital volt ohm meter or a test light ! Two of the four sockets have battery voltage , one should show ground an the last will show open , this is the control circuit from the PCM .

When this happens, it is likely because the headlights came on due to the automatic sensors. If that is the case, the condition is normal.

I own a 2001 Cadillac DHS. The "SERVICE ENGINE


p0071 is the ambient temp sensor which is located by the hood latch behind the grill. They have the yendency just to go bad and you can replace the part for about 30.00 dollars. The dealer is usually higher than a transmission shop. It requires removing the engine and transmission at the same time which means removing the complete frame. A smaller shop may be able to beat the price if you can find one that works on caddies. Some will and some won't. I would shop around.

I have a cadillac 2002 dhs. It has an idling problem!


You MUST determine ("Due to Check Eng. Light") What the Code / Codes are stored in Computer , as they May Lead us DIRECTLY to the Problem.
Having Said that and with & In my Experience, the Throttle Bodies, AND the EGR Valves Get "CARBONE FILTH " Badly and Block Passages that Are in the "IDLE" Circuit of Throttle Body
side, and In the EGR Valve side of things it causes VACUUM LEAKS @ EGR Valve, This Requires physically Removal of and the Cleaning of these parts by hand. Also the IAC> Idle Air Control Solinoid Can Cause this too Or a Mix of All 3, BUT >>>>>>>>>>>>>>
First thing is I need to know Why Check Engine Light is on that is Determine What Codes Exist On Compter P L E A S E RESPOND BACK TO ME WITH This Information and we can go on from here. I Truely Hope I Can Be of Good Help to you. Waiting for Your RESPONSE.
