SUPER BONUS - Honda P1457 Faulty ECM... Comparing known good vs known bad.

SUPER BONUS content companion video. Here we take a look at a 2001 Honda Civic 1.7L with a code P1457. The vehicle was diagnosed as having a faulty ECM, but with nothing to compare to.
Luckily I got access to a like-vehicle....another 2001 Honda Civic... A fantastic opportunity to make a comparison video and solidify the diagnosis.
