I keep getting the same codes thrown, #1,3 and 22. I have alredy replaced the map sensor as of 2 days ago, The Vtec pressure switch and O2 sensor were replace about a year ago. All of these seem to be in the sameare off the wiring harness behind the engine, is it possible that the harness is messed up or if that were the case the car wouldnt even run??
I am also getting the VSS code, but the speedo dosent work right now so i think that may be a different problem entirely. Conicidentally it also come out of the same area of the witing harness behind the engine?

 

First reset the ECU to see whether all the codes repeat. If so, use a multimeter to check the O2, MAP, VSS, and VTEC connector terminals for voltage, as well a short or open.
