Hi there
I’m new here.

I got a 150300 - upper limit value of component hfm-sfi has exceeded

p0101 - mass air flow sensor circuit

I just did an oil change on it recently and changed the belts. Both connectors show 12v going to the sensors and ground is also good. Any tip would be great. Thanks.

Ericson, how can you get a valid code 150300 and get an invalid code P0101 (Blue & CDI do not have P codes) on your scanner?

I used a snap on verus scanner as well as my launch scanner and got those codes from Each scanner.

I'm surprised the other reader didn't pick up the MAF code.

According to the 150300 code, the problem lies with the MAF sensor, but they don't say which one.
