carried out a diagnostic and got code 12 and 13

 

when i disconnect the maf the revs pick up, is this showing that the connection is ok but likely a faulty unit?

 

also the coolant temp sensor, when i disconnect it, the front fan kicks in then goes off when reconnected, does this show that the connections are ok but possibly faulty sensor?

 

also done the o2 sensor test while i had access to the ecu, the ecu is an impul z32a-1262 if that means anything to anyone? i put this as the instructions i followed said with each sensor test it should blink over 5 times in 10 seconds but on mine, each sensor test flashed the light on for 15 seconds then off for 5 seconds then repeated, is this just a different result due to it not being the standard ecu and if so does that flashing pattern mean its all good?

 

hopefully the 2 ecu problems are the reason behind my slightly rough idle.

if replacing the maf and temp sensor, do i have to disconnect the battery for at least 20 mins to get the ecu reset and clear of the old codes or will testing it with a new maf and temp sensor show all clear if i havent disconnected the battery to reset?
