Title pretty much says it all! Driving, listening to my iPod through the CD Changer audio outs, then suddenly there were 4 very loud beeps (almost like an alarm) than nothing.... I pushed the "on" button...nothing. Got home, cycled the key in the ignition, pushed the on button, it looks like a faint background light come one, but nothing else. Seems the radio gave up the ghost.

Any thoughts / ideas? Sorry about the miss spelled word on the subject....should be Loud...not loub. Fat fingers!!!

Thanks in advance.

I have had this happen in my 02 996 when playing CD's. If I depress the "on" button for about 5 seconds continuously it comes back on. Take a look in your radio manual, perhaps it may contain some info.

I had that code before. turns out to be the solenoid that is on top of the engine that get stuck to always on causing the tank to purge all the time.

All the pics you should need are here.

This was a fuel door solenoid replacement - but the EVAP canister has to come out to do that. And, you can see the valve in the pics.

(Thanks to Chuck Jones for taking the pics for me).

Loren,

Thanks for the fast response. Lots of detail. I will take pictures and post the results if this fixes the problem. I had that whole inner shield out last weekend and I bet I must have knocked something loose...

As always, thanks for your huge contributions!

The solenoid on top of the engine is the EVAP purge valve. If you disconnect it or if it fails it pops a P0441 code on my durametric software. I found the cannister purge valve in the right wheel well to be bad. I have it on order and should have it replaced in the next week or so. Will post some pics of the install if it cures the problem.

Loren,

I have searched for an hour and I cannot find a link I previously saw regarding Brake switch install and adjustment. I have installed the switch but still no brake lights. I think it needs adjusted.

Thanks, Tom

Its CEL Gremlin week! Anyone know where following components are located on a 02 996 C4S? Popped the CEL P0447 this week and it comes back everytime I start the car. Searched site for all info and Gas cap seal looks good although I may replace it as a cheap elimination factor...

1. EVAP Canister

2. EVAP Solenoid (Shut off Valve)

Thanks to Loren and all who have responded to the tons of threads on this site that helped immensely in diagnosing my ABS and PSM off lights. Brake switch was bad, should have replacement in a few days and I'll be back in business. Thanks again!

OK, Did some checking; what the normal range is for a MAF sensor on my 2002 996 C4S. My readings are at .94 at idle and about 2.5 lbs/hr at about 2K RPM. Seems low to me. Also, the ABS PSM lights come on when I first touch the brake after I have started moving. Brake switch? Brake lights work?

As always, thanks any advice.

Brake switch, MAF and throttle body affect ABS and TC.

Interseting, then perhaps that could also be causing my P0430 code that popped within a day prior to that! Just assumed it was coincidence and that I had a bad cat!

1) The front sensor wiring has a weak point when the wheels are hanging free on the suspension, the INSIDE wiring will break between the attachment grommet, (on the shock absorber) and the wheel well cause the infinitely many up and downwards movements of the wheels during the years of driving.

2) Check the brake switch.

3) Check the MAF.

That makes sense, I will check the wiring. Not sure what the MAF has to do with the ABS though??? I saw that on another thread. Assuming MAF = Mass Air Flow sensor!

Thanks!

Perhaps the sensors [don't know where they are located] became misaligned when just one wheel was rotated enough so that the error was triggered. I'd simply call the dealer first and see what they tell you. Seems too coincidental for the error lights to pop up right after the detailing effort.

Wheel sensors are bolted into the hub, way too secure to be disturbed by rotating wheel. I pulled all the wheels and looked at each sensor. Was hoping someone else had a similar experience and would save me a trip to the dealers.

Did you do this with the key in the ignition and turned to the first position?

Key was not in ignition.

While detailing my 02 996 C4S I raised each wheel independently and rotated the wheel back and forth by hand in order to clean the inside of the wheels and clean the brake calipers. When I went to start the car to move it, both the PSM and ABS caution lights immediately came on. If I restart the car they go off but after driving for a few minutes they come right back on. I have driven about 300 miles since this occurred and it continues every time I drive. I wouldn’t think the 4 wheel drive is that sensitive or that by simply rotating a wheel independently would cause this but it has. Do I need to have the dealer reset the system? Did I mess up the calibration? Any help would be greatly appreciated.

Thanks!

Bank 2 will be on the passenger side of a Carrera (LHD).

Thanks for the quick response and photo!

OK,

Got a chance to look at the car today. Results are as follows. Pulled plugs and they looked like the original plugs (85k) so it was time to go. Coil packs look good with no evidence of cracking or arcing. Hooked up my SCAN tool and monitored Bank 1 and Bank 2 02 sensors. Voltage and response time all seemed normal on both upstream and downstream sensors. MAF sensor voltage normal and response time normal. Tinny rattling sound coming from Bank 2 cat. Sounds like a loose marble in there... Now to see if I can find a good price on a cat. Didn't want to pull the cat until I have a replacement as it works fine except for the annoying check engine light after driving a few miles. Any ideas on a using a used low mileage cat?

Thanks~ :renntech:

Federal emissions warranty is 8 years, is it not - so you should still be inside of it.

Thanks, just a tad over 80K... I like to drive B)

Popping P0430 code on my 2002 C4S. No mods of any type and all serviceing up to date. BUT, car is out of emmsions waranty. Barely Of course... :) Returns after a few miles of driving with no other codes but the 0430. All research leads me to believe it is a Bad Cat plus when the engineis hot I can hear what sounds like an exhaust rattle. Question here is; Can someone tell me if Bank 2 is on the drivers or passenger side of the car. Any other advice greatly appreciated including PN of cat if known. Thanks!
