Code 56

[Tony91LX]

Scanned codes last night got the following;

14 : Intermittent PIP signal operation. Suspect PIP sensor or TFI module, or grounding or interference problems at the TFI module.

56 : MAF sensor voltage too high.


I replaced the TFI module helped my revving problem that I was having, what’s Code 56?, and how do you clear the codes, I replaced the TFI and I am still getting Code 14


Thanks

If I remember correctly, you have to insert and remove the scan tool 3 times with the key in the off position (maybe it's the on position). This erases all the codes. Sorry I can't be more sure about it...
