SOURCE: I FAIL THE EMISSIONS CODE# P0410- SECONDARY AIR INJECTION

I have a 2001 STS that had the same problem - Service Engine light and returned the P0410 code. It ended up being a small rubber hose that had pulled off one of the plastic lines in the secondary air system. In fact, I just fixed this last night.

Pull off the top engine shield (the one covering the motor and the fuel injectors, not the plastic one at the front of the car) and look for loose lines, hoses or wiring.

Also - if you remove the shroud under the engine (you just have to pull out a bunch of plastic retaining plugs) you can get at the lower elements of the SAS. Look for loose lines, hoses or wiring.

You could be fortunate and just have a loose line. Does the caddie run OK?

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.

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.

While driving my car over drive light comes on in a few min. the car dies


Does it die at stops or with foot off throttle and coasting? The overdrive light coming on like that is the transmissions equivalent of the engine check engine light. Fault has been detected and code stored. Would suspect with information provided that the torque converter clutch is locking up but not releasing. You may be able to have this code retrieved with an OBD2 scan tool or at local parts store. You are looking for codes in the 700 range as these are all transmission related codes. ie P0741 or P0742. The P0742 is for torque converter clutch stuck on. P0741 is TCC stuck off

Suzuki 2005 verona codes coming up are P0700, P0741, P0733 and Po734 what do these mean


bad A/T
automatic transmissions are complex, and expensive to repair /replace.
take it to an ASE pro.
The suzuki has factory codes too, so you need them for full diagnosis.
that takes a special too, not just your generic P0 codes.
this tells me , the tranny is slipping
tcc not locking up and 3nd and 4 gear , not right ratio.
slips. and that is serious. get a full diagnosis.
5sp M/T/s rule, A/T not.

MY 2002 CADILLAC SEVILLE HAS CODES COMING UP WHAT DOES THESE CODES MEAN


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.

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.

I've had transmission overhaul kit performed Oct 2007 on 2001 Cad Deville: incl upper/lower valve body w/solenoids,imput carrier, converter @ 77K miles. My check engine light came on a wk ago at 91K...


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
