Default TMAP CEL? - 10-05-2020, 12:06 PM

Hey everyone,

I've been randomly having this CEL come on and off intermittently. I'm trying to understand why and what may be causing it. I've got two logs attached for with and without the CEL as well as the codes for when it is coming on.

121201 TMAP Signal Active with engine off
102001 Air mass, plausibility - Tuner code, ignore

Box hasn't moved positions and is still secured where I zip-tied it.

Usually this is caused by a loose OBDII cable connection. Also worth opening the enclosure and checking both sides of the JB4 board to ensure no elemental damage.
