    I got a 90 CRX Si with a B16A2 block and a JDM B16A head with a PR3-J00 ECU (Pre-OBD). Just recently my ECU started showing a code 7 (Throttle Position Sensor). I checked the voltage for both the red and yellow wire and everything seems alright. I checked the ground but the resistance seemed a little high. It was at 8 ohms. I figure it should be more like 0.4 ohms, but I could be wrong. I also figure if it wasn't working properly, my engine would stumble when I suddenly change how much throttle is applied, but this isn't the case. So I guess its working, but why the ECU keeps giving me that code 7 is beyond me. Any advice?
