ASE A8 Practice Test - ASE A8 Engine Performance Test Prep - Test 1

Got 'em all! The hardest section for me would be turbochargers/superchargers since I've hardly worked on them. I only know how they operate and the components they use in theory.

Question 10 seems wrong. With a 24% LTFT isn't the PCM adding fuel indicating a lean mixture?

[@FreeASEStudyGuidescom]

Thanks for the input, Obozo Clown! Question 10 is an EXCEPT-type question. They can be confusing; all the answers fit except one; A dripping fuel injector results in a rich air-fuel mixture. The ECM subtracts (-24%) fuel to compensate for a rich air-fuel ratio and adds (24%) fuel for a lean air-fuel ratio. Therefore because this is an EXCEPT-type question, answer B, a dripping fuel injector, is correct.

Dude, I was like WTF on the #10 question as well. Then I saw this comment, ohh I guess I missed the “EXCEPT” word as well! 🙄

Read the question

Question 1 answer is wrong. The PCM recieves a signal from the knock sensor to advance the timing and the knock sensor sends an ac signal the PCM to advance the timing due to detonation.
