01 Saturn evap canister location? Sign In

This 01 Saturn coupe with the DOHC engine won't pass inspection because it has 2 "Not Ready" I/M monitors. One is the evap system and the other is because of the secondary air pump system is at fault.

The air pump is working and the solenoids and check valves are all OK. We've replaced the upstream O2 sensor just to be sure, but we do not know what keeps this system from being "ready".

Texas will allow one "not ready", so we are going after the evap, but I can not locate the evap canister, and I just discovered that this car has been wrecked, so it's a good likelyhood the canister is cracked.

Where is the canister ?

Monitors not being ready means that someone has cleared all the stored data recently and now it needs to experience every situation the system monitors so it can have a passing grade. It's just a matter of driving it normally until all the monitors have completed their testing.

I have driven this car over 70 miles TWICE since clearing the trouble code 0410. Others have driven it miles and miles since it first failed the inspection for "secondary air system" NOT READY and "EVAP system" NOT READY.

New gas cap. New upstream O2 sensor. New secondary solenoid. New gaskets on stainless pipe from second air pump to exhaust manifold. Pump runs the proper 65 seconds on start-up, pumps air and then stops. Check valve seems to work. All the hoses in and around the secondary pump, solenoid and check valve are OK.

What and where is the monitor/sensor for the secondary air pump and what and where is the monitor/sensor for the EVAP system?

This has been a nightmare for the owner who paid for the (failed) first inspection on 9/10. She has 15 days for the free re-inspection and then it's another $40, and she's already spent nearly $300 on aforementioned non-fixes.

OK, here is exactly what is required to complete the drive cycle and reset the monitors.

My friend gave up and we took the car to a dealer. A new check valve and $250 later and still 2 "not ready" monitors. That part had already been replaced by the previous owner. Doesn't GM have a record in their computers of what parts/maintenance has been done on that car?

Why can't I find out which sensor(s) are involved in these two systems - EVAP and 2nd air ?

Replacing sensors will never reset the monitors. Nothing but drive time will reset monitors. Every time someone clears a code in the computer, the whole process starts over again. That's the reason they won't pass you until the monitors reset because all people would have to do is clear the computer before the testing. The computer has to finish running all it's self tests for the monitors to be reset.

We can't clear the monitors. This car has been driven and driven and driven and driven some more, and the two monitors will not get ready, therefore the car can not pass Texas inspection. And after driving the vehicle it re-sets 0410 AGAIN, and the same two flags are
"not ready".

I connect my code reader and drive the cycles you gave me and watch all the flags clear but the same two. Then after a few stops and starts, the 0410 sets. We do another "repair", go through the cycle and the same two flags will not "get ready" and then soon thereafter the 0410 sets again.

We have been doing this for 2 weeks and about $400, and we are still two flags "not ready" and code 0410.

We are going nuts.

Apparently, you haven't resolved the PO410 as yet. This is a problem with the air pump system.

Here is the flow chart for that code. See if it helps you.

I haven't read this whole thread and don't have all the exact info but will just add a little background on the moniters.

As you already know all the moniters have certain codes they set when run and something fails. There is a certain order they run in, from A to B to C and so on. If for some reason B doesn't run or pass the C, D & E won't run til B runs and passes.

Some systems require other systems to be working so they can use them to run their tests. If they don't work, the tests can't be run.

On thing you have to becareful on when you have 1 or more moniters than haven't run with 1 code only...... Once you fix that system and the other moniters run, it's very possible some new codes that have never been seen before could pop up due to previous problems that went undetected due to the moniters not being able to run. If the customer isn't aware of this before hand, now all those brand new codes are your fault because they were never there until you touched the car....... BTDT

We have not corrected the problem...YET, AND the owner of this vehicle can't catch a break.

Last night a next door neighbor coming home at 3 AM after having a glass of wine or 16 slammed into his pickup sitting about 40 feet behind the vehicle from H*ll. Cops estimated her speed at 50 to 60 MPH, flipping her truck and probably totaling his truck.

No apparent injury to the woman. Her 3rd DWI crash this year.

Is this karma for our trying to figure out how we could burn the car from H*ll?

Thanks so much for the additional info on setting and clearing flags. We ain't giving up, but we are losing our minds. I can't thank you enough for scratching your heads with us.
