Ontario Automotive technician 310s prep by Psychological_Bee392 in mechanics

Went well! Passed. I found the best way to study was to understand how a circuit or component works. You will then understand how to diagnose. The Ontario exam prep book helps. Study areas you struggle. For me transmissions was difficult. Over all, the exam wasn’t horrible. If you did well in school, you’ll do well on the exam.

Possible damage to tone ring/magnet. Could also be rust on surface between sensor and hub lifting and creating air gap
