hello there,

the ecu has these 2 errors,

P0102Mass air flow sensor circuit low input
P0113Intake Air Temperature Sensor Circuit Malfunction (High Input)

anyone has any idea what may cause them?
it's a my02 euro bugeye wrx.
thanks

 

knackered air flow meter

 

but the car runs ok, I think...

 

Check the connector on the MAF. The MAF and Air intake sensor are all the same unit so could just be a loose connection.

 

p.s. Also worth having a good look at your air filter and the pipework from the airbox to the MAF.

 

I have changed the air filter a few days ago, the connector looks ok.
the check engine light flashed 2 times a couple of months ago and a few days ago when I pulled the connector with the car running.
after this I've done a few kms and the car seems to be ok.
next week it's due to service, engine oil, oil filter and fuel.
if the check engine light flashes again, due to this errors, I'll guess I have to buy a new maf...
thanks for your help.

 

tried to disconnect the maf and the car didn't stalled, only at the second attempt.
guess I'll have to buy a new maf.
trying to find a new one for £100, have replied to other posts but no luck so far...

 

today identified a new fault, PO301 - cylinder 1 misfire

this is also related to maf or what? still haven't bought a new one...

 

anyone? is it just the maf or something really bad?
thanks

 

anyone?

 

Have you solved the problem with the other codes yet?
If no then check the MAF connectors or loom/ fit new MAF/clear errors and reset ECU then see if new errors show up.

 

the maf connetors are ok, after disconnecting the maf with the car running, the car continued running, only stalled at the 2nd attempt.
I still don't know what caused the 3 fault codes, can't see anything wrong with the car, just think it wastes more fuel, a little slow to get to 200 kph and this 3 fault codes...
don't want to spend £240 in a maf right now... or in anything else for the car guess I have no choice and buy a new maf...
