Engine light on error The error MAF Sensor Circuit Low Frequency?

[Justin2067]

Hi I have a vy berlina with a ls1 , mafless tune stock intake but disconnected maf. Engine light came on last night The error when scanned was MAF Sensor Circuit Low Frequency or low voltage .. At same time aircon stopped working ? Airflow meter unplugged so not sure what is causing this and how to clear error ? Car drives perfectly ? Any suggestions welcome

with mafless u will always have a maf error (its failed on purpose) its just ignored so it dosnt show, it forces SD operation thats how u get mafless tuned, u should also have a iat sensor separate

X2. And don’t plug your maf back in

What’s a iat sensor? I have car at auto electrician this weekend to sort I’m assuming there’s another error as well as oztrack have said a maf issue won’t through up a engine light on its own ? But car runs great otherwise still goes hard

Done that many times dosnt do anything as the tune has disconnected the plug and does nothing I’m told

intake air temp sensor, its usually in the maf but when removed it has to have one fitted separate

if maf is plugged in it will generate a signal as u cant ignore or turn off the signal thats why it has to be removed (unplugged) to fail it and go mafless, if its plugged back in it will use it for fueling and if the tables are populated u may survive but some can zero them out or some will leave stock and u will just have wrong fueling

Yes it has air temp fitted still has stock intake so yes . Been working so far for over 2 years
