I checked my ECU today again and there are five problems listed as
follows:

Code 3: Map Sensor
Code 7: Throttle Position Sensor
Code 9: CYP Sensor( NO 1 cylinder position), this may be the reson
that is why my one cylinder does not work
Code 10: IAT Sensor
Code 14: EACV


I only know where is Map Sensor but do not know where is the others.
Could you tell me why I got so many problems? Can I reset them again?
or I have to change all of them? But I really do not think all of
them are bad.

Many thanks for all suggestions!!!

 

Man, you setup is in rough shape.

Give me what year/model car you have, what year/model motor you have in it, and what year/model ECU you are running.

The more info you give the bettere we can help.

I think the code 3 adn 7 is caused by you reversing the MAP sensor and TPS plugs. You will notice that the two plugs are the same. Try switching them to see if that takes care of the 3 and 7.

yeah and the IAT and IACV can be easily switched too. try switching those around too.

 

He probably swapped a B16 or ZC into his dual point crx that has the most messed up engine loom ever and didn't bother to pull it apart and rerought everything. I had to do this on my friends 88 CRX/B16A. The damn TPS wire is reversed so you have to swap that around. Salvatore Leone is right too it's really easy to put ur Green IAC connector on the IAT and maybe the Tandem valve on the IACV. If you don't run new wires for the CYP then you'll get a code for that. But if I'm right about the car then he shouldn't be able to too easily mess up the TPS and MAP cuz the MAP on a CRX is mounted on the firewall and isn't even wired into the engine loom. Oh well i was bored and i'm probably wrong but just thought i would go off. Latez

My car is 90 Honda(or Acura) Vigor CB5. All the plugs here is very easy to identify as they are all different. so I think this could be not a problem.

More ideas?

 

So this just suddenly happened? All the codes came around the same time and you didn't change anything? If that's the case, try resetting the ECU and see if it happens again. Maybe your ecu is messed up.

 

Thank guys! After I reset my ECU, all the trobble codes gone!!

But I should say it is better to remove the battery than just the fuse!!!
