What do these codes mean

[leegt5]

Run VAGCOM on my car as it sounded like it was misfiring under load. And slightly lumpy (Subaru) on tick over. I read on here that the maf is a constant pain so tried unplugging it to see if it ran any better but didnt and the yellow dash light came on so plaugged it back in and it went out.

Then ran VAGCOM and these 2 faults came up. To make sure it wasn't because I unplugged it earlier I cleared the 2 faults and run it again but the same two came up as below

16486 PO102 Mass or Volume Air Flow Circ Low input

16501 P0117 Engine Coolant Temp Circ Low input

What do these 2 mean and would they cause the symptoms I described ?

Car is totally Standard by the way !!

Cheers in advance !!

So I take it I need a New Coolant Temp Sensor and MAF !!

 

[The MoffMeister]

or try cleaning maf with some k&n solvent cleaner stuff but sensor will need replacing

Cool just cleaned the MAF with Propyl Alcohol and bought a replacement Coolant Temp Sensor... Gonna wait for it to cool down before replacing that though !!
