New and hoping for help
I have a 92 prelude with a f22a6 (i know it could do a lot better 
) and have recently found out that my car has more issues than I thought. I checked the codes and it came out with map sensor, exhaust gas recirc. (EGR), electronic air control, and,... speed sensor. I have been all over trying to find out more info on these problems. I was told to buy the Helm electrical guide to check if there was a common link between any of these codes. No one has it, not even helm apparently. If anyone has any pointers or ideas on things to check I would really appreciate it.

Ur ganna want to get that map sensor problem fixed soon, the egr I wouldn't worry about at all, I got the cel for egr all the time, u can check the sensors with a voltimeter if u have one. But without the map sensor working, you're running extremely rich! And if u leave it on for a while, it's ganna foul ur plugs, and get lotsa back fire, and get terrible gas mileage. I would try swapping out ur map sensor with another one. Good luck.

My Prelude is also a 92 and I have one of the factory manuals that the Honda techs use (not Helms- this is published by Honda Motor Co.). The manual has info on both the H23A1 and the F22A1 engines plus any other info on the vehicle. It has the codes and troubleshooting flowcharts for each code, but it requires removing the ECU and using a multimeter and test harness to check them properly.
I don't know if you already tried it, but the first step to check for any codes is to reset the ECU in case the codes were flashing in error. To reset the ECU:
- Turn the ignition off
- Remove the "CLOCK RADIO" 10A fuse from the fuse box under the hood and leave it out
for 10 seconds, then replace
*If you have a factory stereo which requires the code card to reset it, make sure you
have it beforehand. Otherwise, just reset your clock and head unit presets
If the codes come up again, I can scan and send you the troubleshooting flowcharts and diagrams for the codes you listed. If you want them, send me a private message and I'll get them to you.
