Resetting ECU after cleaning MAF? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hentai · 11-26-2015, 10:28 PM

I just cleaned my MAF with CRC maf cleaner
Just wondering if resetting the ecu (disconnect battery)
& letting it idle for the first 10-15mins would make any difference in it's learning process again?

Or should I just drive and let it learn from then on

Thanks

Ecu is always learning no need to reset, only need to reset to clear cel codes

Yep, like @steve99 says ...... the ECU is pretty smart.... it will figure it out ......

Why did you clean your MAF? That can do damage to the sensor. These cars are not like older vehicles.

The CRC maf cleaner is pretty safe, should cause no damage there. Letting the battery remain disconnected for a little while will reset the ECU though it's not entirely necessary. Essentially it shouldn't make a difference but it won't hurt.
