The P0134 code means that the air fuel ratio sensor is not operating. Most of the time it will need replacing to correct. The P0327 code means that your knock sensor is not getting enough voltage. The P03FF may indicate an internal failure of the ECU. It is possible that the ECU issue is causing the other sensors to malfunction.
