This very smart man shows you how to modify the engine bay sealing surface to let the hot air escape from the engine bay. I did the mod and checked it with a digital thermometer gun and it does help, you can feel the hot air escaping. If Chrysler did this when building the car maybe the computer would last longer. What a stupid place to put the PCM 6" away from the turbo.

I'm having problems with my 2004 PT Cruiser Turbo Touring. First got P0032 and P0038 and car stall out on the highway. Pretty scary when your car dies on the highway, thought it was going to be my last day on earth. Waited about 10 minutes and it started back up and drove home.

Changed both upstream and downstream O2 sensors with NTK (NGK) sensors. Check and cleaned all grounds, by battery box on fender well, and both sides of grounds from struts to under fender well. Outside my garage the engine just died while idling. Showed the same codes again. I just ordered a reman PCM from AllComputer and hope that it cures the problem.

The car was previously owned by my 90 year old father and only has 47K miles on it. I love the style of the car, and always thought Chrysler were quality cars...now I know better.

A couple of years ago I got a reman PCM for my PT from the same source.

It was truly plug-n-play and I've had no issues with it. :cool:

If that PCM doesn't work out for you, we have a member here that rebuilds them and he's very good at it. Not only that, but he stands behind his work. His name is Myckee. You might get in touch with him if your new one doesn't work out.

This mod sounds like a great idea. I'll modify mine asap as I've already replaced the computer once because of those codes and I'm sure it failed from the under hood heat. I've already baked several sets of windshield washer nozzles to a crisp ( literally ! ) Following the same process would it make sense to make the same mod directly above the computer ?
I got two reman computers from a place in Florida (this was about two years ago) and they were worse than my original which was throwing the codes. I ended up having a brand new computer installed at the dealer and having them flash it. Haven't had a problem since. Odd thing though, even though the bad computer was throwing the codes the car still ran perfectly. So what do you think about opening up another section of that seal area ?

Aloha George,

After checking the BBB Complaints for CarComputerExchange, I canceled my order with them and sent my computer to SIA Electronics. They just received it today, so time will tell. Now I have my fingers crossed that CCE refunds all my money, from complaints read they like to keep as much as they can.

As far as creating a vent above the computer, thinking about it, I wouldn't do it as the chimney effect will cause the hot air to go by the computer. The way the guy in the video does it makes sense, venting away from the computer.

Aloha Chuzz,

Do you have an email address for him? or how can I contact him?

This is all based on the assumption that the computer is at fault and that a failure is heat-related, and that that heat is delivered from the engine compartment. Too many assumptions and not enough proper diagnostic work.

Don't be surprised if you get a report back that your old PCM cannot be repaired. ;)

I have heard of several people that have sent PCM's in to these "repair service" places only to be told later that the PCM could not be repaired and they would need a different one.

This is what a PCM looks like inside (this is the old original PCM from my PT):



Everything on the circuit board is "sealed" or "weatherproofed" under a viscous compound:



I don't know how they would remove or peel that goo off the board to be able to replace anything on it that may be causing the PCM to fail. ;)

Member "myckee" might know as he works on PCM's.

Thank you for the video, may get to it soon. I wanted to do that to the front, cut a small length infront of the battery, put a plastic air scoop there to channel cold air into my stock box while driving.

Aloha 06PTElectricBlue,

Just got a call from SIA Electronics today. They said my PCM checkout okay and were shipping it out today. I also asked them to disable the SKIM and the guy on the phone said they did. They charged me $89 for the checkout and return shipment. Hopefully, it will be okay, as I removed the immobilizer unit today. Just want to remove as many possible potential problems. I will report back when I get the pcm installed.

Aloha Chuzz,

I live in Makaha, Hawaii...was brought up in Kaneohe. Don't know anyone by Bardago, don't know much anyone as I live a very secluded retired life. Only sports at trying to keep my PT alive and Trap Shooting.

That's cool, Don. His wife works at the local hospital and he pretty much sits on his butt or goes to the beach. He's gotten so fat and lazy, that he doesn't even go hiking in the mountains with his ONLY child. A son who loves hiking.

I finally bought a pcm from Myckeee and my problem was solved. I had him disable the SKIM, so now I just use a regular key and keep a spare in the wallet just in case. The only drawback is with the SKIM disabled you get a tiny red light glowing in the center of the L gauge cluster witch doesn't bother me at all.

CarComputer Exchange is trying to rip me for $508, still haven't received my refund on my canceled order. SIA Electronics also is another loser, said my computer tested ok, but in fact the computer is bad and replacing it with MycKeee's pcm proved it. I would definitely stay away from both of these companies.

I don't think any of these Internet PCM companies actually repair computers. I think they just grab another used one and send it out and hope for the best.

Glad to hear that myckee was able to help you out, and that the PCM was the issue all along :cool:

But why did you have him disable the SKIM?

The only thing I see in any of your posts was that it originally had error codes that were related to the O2 sensors, not any problem with the SKIM.

How did you pay for the CarComputer Exchange PCM? If with a credit card, you should be able to do a chargeback through the credit card company and they should be able to get your $ back.
