Code 507 is for a problem with the idle speed control being too high, and code 741 is for a problem with the torque converter clutch circuit.
You would check for vac leaks and see if the idle air control valve is working, and check the circuit for the torque converter clutch.

First thing you have to do is list all the codes, because some some might be stored for a long time. Pushing the OFF and WARM buttons together and holding will ghive you all the stored codes. Then press OFF and HI together to clear all codes. Hold and wait for bars or 0's. Now start your car and let it get up to proper operating temps. Take car for aride that aincludes all phases of driving including highway speeds. Observe SERVICE ENGINE LIGHT for coming on . Assuming it does , repeat steps previously provided, read codes stored and repair accordingly. If need be contact me with new codes and I will try to assist you.

SOURCE: My cadillac deville has the following engine codes

click on the below links for code details.
P0106

P0121

P0171

P0174


P0335


P0340

P0385

P0442

P0506

P0507

P0601.

all of the above codes seem to have a common cause, they all list a bad ecm (computer) as being a cause, and the last code P0601 points specifically to a bad computer. sorry for the bad news, hope this helps.

Check the fuses/circuit breaker for the heated seats, check the switch but most likely it is the pad under the seat cover. This is a high failure item.

Have 2002 Cad. Sev.that battery was disconnected pos. first, now the tach quite, turn sig. and speedo. quite has obi 2 readings of P0507 P0650 and P0741 can you help PLEASE?


I don't know those codes, you can google them and find them, or try googling "OBD-II codes" (OnBoard Diagnostics) to find the codes and meaning.
What I jumped in to say, was it wouldn't matter if you removed the positive or the negative cable first, AS LONG AS THE IGNITION KEY WAS IN OFF. So if key wasn't in ON, you can take off either cable first. People only take off the negative first as a safety precaution: if you take off positive first, there is a chance you could cause sparking with your wrench touching any metal on the car, or if the positive cable terminal touched metal before you take off the negative. Always, just for safety, take off the negative first. Also never take off the battery when the key is in ON.

0507- Idle control system too high.
0650-Malfunction indicator lamp (MIL) control circuit malfunction
0741-Torque Converter Clutch circuit performance or Stuck Off

2002 CADILLAC CANT PASS SMOG


P0507 code idle speed is high than expected. Partially stuck open thermostat can make the computer think that the car is cold and command a higher idle speed. A small vacuum leak will also raise the idle speed. Throttle plate not fully closed cause this condition. Once problem is solved then clearing codes will leave computer monitors at incomplete which will still fail state inspection by driving the car over several days with a fuel tank between 15%-85% will allow them to run to completion. Ask your state inspector how many monitors need to run to completion the hardest ones to complete are EVAP, SEC.AIR, CAT.

yes they are all right, i suspect that this vehicle uses encrypted software for the gearbox computer and this is the reason for the different codes ,i never use a code reader as on europeon cars they just show cannot connect to vehicle ,i use a voltmeter and a dwell meter plus a frequency meter and a scope to diagnose problems .So i suspect

P0741....Torque Converter Clutch Circuit Performance or Stuck Off


P0507....Idle Control System RPM Higher Than Expected

that this dealer doesnt have the correct diagnostic software because their code is a generic code as well as the first one ,A GM dealer code would have been P1507 and this code doesnt exist in the GM list of codes ,i think they are both right and need attention but the gearbox code is a fault with the front clutch operating mechanism ,i would advise ripping teh autobox out and fitting a manual gearbox ,lot less hassle
