How do I check codes on my 2002 Cadillac dhs - 2002 Cadillac Deville

SOURCE: How do I read the

if it's the check engine light. since your car is 1996 and newer take it to the local autzone, advance auto (free) have them plug into it and read the codes (OBDII). take a pen and paper so that you can write down what comes up. Or take it to your local mechanic and have him/her read the codes ($Free-$60). anything outside of the check engine light, you will need to go to a garage / dealer.

SOURCE: 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.

P0741 Torque Converter Clutch Circuit Performance or Stuck Off

Your car actually has a viscous converter clutch inside the torque converter instead of a (mechanical) torque converter clutch to lock up the torque converter for fuel economy improvement. You will see it referred to as the VCC and/or TCC.....

The TCC/VCC has a variety of components in the system including an electrical circuit supplying the transmission, the apply solenoid inside the trans, the torque converter itself, the PCM that controls the apply, etc. It is impossible to diagnose from afar. Unlikely that it is a "sensor" inside the trans as the PCM controls the VCC apply and uses engine and trans data that it receives from a variety of sources. If a "sensor" had failed the trouble code for that sensor would be setting......

Something as simple as the brake switch can cause the VCC to not apply correctly. There is a safety switch on the brake pedal that activates the brake lights and disconnects the VCC circuit. If it is misadjusted then the trans cannot apply the VCC. Lots of other trouble shooting items on the VCC system. If you don't have a service manual and cannot trouble shoot the system, I would recommend a Cadillac dealer as they have the trouble shooting information for the specific VCC that the Cadillac 4T80E trans has that a trans shop is simply not familiar with. No sense working on the trans until you actually know what is wrong.

Re: I have a 2002 cadillac dhs and the check coolant level comes on. The coolant sensor is located in the overflow bottle and it is prone to failure. Unfortunately the only way to get it is to repl. coolant overflow bottle.
