    Narrowing down EML woes

    Can someone peer review my thinking?

    So I’m throwing an eml light while driving randomly. May come on 20 minutes into a drive or 5 minutes. Never stays through a key cycle but always seems to come back on after a little driving.
    Limp mode only ever kicks in if I’m very aggressively driving, or hitting the limiter (on accident)

    So, onto diagnostics; using inpa, I can see that code 118 (tps #1) was thrown 4 times, 119 (tps #2) was thrown once, 120, 121, 230 all thrown once as well.

    So since 118 was thrown the most frequently is it safe to assume that’s the origin of the other three codes and therefore my tps #1 is to blame? Is this a correct way of diagnosing or is frequency number not a function of error origination?

    I know I can just replace my front TPS to find out if that’s my issue. Not really asking someone to solve my issue but more to tell me if the sensor that has the highest error frequency is most likely to blame for the other codes

    Seems as tho loctite is a useful tool when replacing small low torque TPS bolts... front tps was loose
