sjbrowning7 Posted May 11, 2014 Share Posted May 11, 2014 So was checking the codes because the cel came on sometimes recently. Got two codes; 34 and 42. Does code 34 mean I need another map sensor I take it? Also I don't have a scooby about 42... Apparently to do with reading speed? Can anyone shed some light on this?
