84 Gen1 CRX PA Sensor.... code 13 Atmo sensor issue hey all - im new... i have a 1984 Honda CRX Ballade Sports running a D16A3 motor and recently installed a HKS Supercharger. im also using a PR5 ECU with a chip which came with the supercharger - however its throwing a code 13 at me (PA Sensor). Original ECU is a PG7 but while using that the car doesn't want to run good up to 5000rpm, on the PR5 it cuts revs at 3000 and the code is on... code 13. The car doesn't have a PA sensor to my knowledge so i sourced one, tried connecting it up using the general info available on the new C9. C12 C13 --- but once connected i can't start the car. Any ideas??? Help pls... i want this car to run and its meant to run on this chipped ECU - how do i get rid of code 13? is there any other way the PA Sensor is meant to be hooked up?
