Cheers mate, thought the first one was temp sensor, strange about the maf tho, car idles ok but when u disconnect the plug it stops.....just wondering whether the temp sensor is making the car run rich and making the maf sensor run faulty???

temp sens could be doing that mate but dunno if it would affect the maf??

21 is engine coolant temp sensor ,
23 is air mass sensor ( air flow meter)
think you may find that the 23 code is being brought up as a result of 21 code being faulty so if you replace coolant temp sensor for ecu you should be laughing
