Need Help Quick w Code
Need Help Quick w Code Running Data master on my 95 T/A OBD 1. Have MALF 43 ECS Failed. I thought this code meant bad knock sensor, changed it and there is no change. What does this code mean? Do I have to disconnect the battery or pull the PCM fuse for this to reset?

Could be a wire, the connector dirty or loose, the ESC module in the PCM, the PCM, etc. There are diagnostic procedured in the shop manuals for diagnosing these codes.
