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.

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.

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.

Removal of egr valve in 93 cadillac, didn't pass smog, want to check egr valve


I would not remove it unless its bad. did it not pass smog because of that? the valve either good or bad and does not need to be removed to check it. it either opens or it doesnt with vacuum applied.

Have a2005 deville with the code po741 cant pass ca. smog need to what dose it takes to fix this problem


Hi,

Code P0741 = Torque Converter Clutch Circuit Performance or Stuck Off. This relates to your transmission only and has nothing to do with Exhaust emmissions.

If failed smog test, there must be an issue within your emmission system, e.g. sensors etc

You will need to have your codes read again, or have your vehicle properly inspected.


Cheers,

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
