MTTC Automotive Trade Test study guide
MTTC Automotive Trade Test · Work through your exam, one topic at a time.
The MTTC Automotive Trade Test is a Michigan certification examination for people who want to teach automotive technology in the state's schools. It is designed for career and technical education candidates, career-changers from the repair industry, and others who need to demonstrate that their hands-on shop knowledge meets the standard for a teaching credential. The MTTC Automotive Trade Test study guide has 9 sections and about 2,174 words.
01Engine Repair and Engine Performance
A candidate must be able to explain the four-stroke cycle (intake, compression, power, exhaust), valve timing, and how camshaft profile and timing affect volumetric efficiency. Know the difference between mechanical and vacuum advance, the role of the mass airflow (MAF) and manifold absolute pressure (MAP) sensors, and how the powertrain control module (PCM) uses oxygen sensor feedback to trim fuel.
331 words, about 2 min02Automatic and Manual Transmissions and Transaxles
Understand torque converter operation (impeller, turbine, stator), planetary gear sets, clutches and bands, and how a valve body directs hydraulic pressure. For automatics, know line pressure, shift solenoids, and the role of the transmission control module (TCM).
267 words, about 1 min03Suspension, Steering, and Alignment
Know suspension types (MacPherson strut, double wishbone, solid axle), spring rates, shock absorber function, and the purpose of sway bars. Understand steering geometry: camber, caster, toe, steering axis inclination (SAI), and included angle.
254 words, about 1 min04Braking Systems
Understand hydraulic principles (Pascal's law), master cylinder operation, proportioning valves, and the difference between disc and drum brakes. Know how antilock braking systems (ABS) use wheel speed sensors and hydraulic control units, and how electronic stability control builds on ABS.
262 words, about 1 min05Electrical and Electronic Systems
Know Ohm's law (V = I × R), series and parallel circuits, and how to use a digital multimeter. Understand battery construction, starting and charging systems, and the role of the alternator and voltage regulator.
233 words, about 1 min06Heating, Ventilation, and Air Conditioning
Understand the refrigeration cycle: compressor, condenser, expansion device, and evaporator. Know pressure-temperature relationships, refrigerant types, and the purpose of the receiver-drier or accumulator.
240 words, about 1 min07Safety, Tools, and Shop Practices
Know personal protective equipment (PPE), safe lifting technique, jack stand use, and proper tool selection. Understand torque wrenches, micrometers, dial indicators, and how to calibrate and store them.
213 words, about 1 min08Career and Technical Education Foundations and Instruction
Understand how to plan instruction using learning objectives, formative and summative assessment, and differentiated instruction. Know how to align lessons with standards and industry credentials.
185 words, under 1 min09Workplace Safety, Environmental Compliance, and Professionalism
Know hazard communication, safety data sheets (SDS), and proper storage and disposal of fluids, batteries, and tires. Understand EPA rules on refrigerant recovery, used oil recycling, and spill response.
