BIG SHAFE Posted August 22, 2006 Report Share Posted August 22, 2006 I have a P1543 DTC on the SS. I know that it is listed as a "a/c system performance", is this just a general a/c problem or does this refer to something specific? The a/c doesn't blow any cold air, but the a/c clutch engages, any ideas? Thanks. Quote Link to comment Share on other sites More sharing options...
VikingY3K Posted August 22, 2006 Report Share Posted August 22, 2006 A P1543 on OBD-ii? Its eigther P1539(High) or P1546(Low) and this error is do too voltage* eigther too little or too much. I think you might have a loose wire/bad ground somewhere. I'd check your wires before anything else. You are right though its a (Air Conditioning (A/C) Clutch Feedback Circuit) error. I'm not a car expert, but this info. might help ya. Goodluck. Quote Link to comment Share on other sites More sharing options...
