What does the code mean when light flashes 5 times was flashing 7 times and I replaced the speed control switch.

Check your filters. Manual says they need to be cleaned every two weeks under normal operation (and in my case more often during renovations). It seems it may not take much to limit air flow enough for the indoor unit to trip out. Hope this helps.

Therre is no DTC code "5". The DTCs start at 12. If the knock sensor (there are actually 2) was bad, you would have an acceleration issue. The knock sensor changes the timing of the spark to eliminate detonation, or "pinging". Do you have a "Ping" condition/valve rattle on acceleration?
To reset the light, open the hood, remove the 15 amp EFI fuse for 5 minutes. Replace it, and start the car and drive it until it reaches operating temperature. If the light comes back on instantly, you have a bad sensor or a bad wire.

I had the same problems that most of you have been having, tv turning on and off, lights flashing in all different colors, having to unplug tv to reset and all of that good stuff. I noticed that most of the time this would happen once the tv would start to heat up, and I could hear the fan working a little harder. Well I am not an electrician but It was very simple to unscrew the lower bottom park of the tv, where the fan and most of the electronics sit, then I used an oxygen tank ( I work for a medical company ) to blow out all the dust in the tv, ( you can olso use the compressed air use for computer, but if grandma or grampa have some O2 laying around, it works really good, LOL. )and was very surpriced to see how dusty it was, then I removed the MAIN FAN ( you only need to remove three screws, however there's a box in fron of it, which you'll have to remove first in order to get to the fan ). this may sound a little complicated, but trust me it is not, once you have taken the fan off, clean it all the way around ( best to use a clean rag, the compressed air was not doing the job.
long story short, once I cleaned the fan and put it all back together. The TV still didn't work LOL, Just kidding, It has been working perfect for a little over a week.
If I can help in any other way, please e-mail me @ [email protected]

hope this helps.

That control board is several hundred dollars. If I may make a suggestion, take a jumper and when the inducer fan starts, jump out the pressure switch. If it starts, it's not the board but a bad switch, hose or blocked exhaust vent.
