Common ASE Engine Performance Test Questions and Answers
Here’s a breakdown of some typical questions you might encounter:
1. Engine Components and Their Functions
Q: What is the function of a crankshaft position sensor?
A: The crankshaft position sensor monitors the crankshaft’s rotation speed and position. This information is relayed to the engine control unit (ECU) to manage ignition timing and fuel injection.
Q: Describe the role of the piston rings.
A: Piston rings provide a seal between the piston and the cylinder wall, preventing combustion gases from leaking into the crankcase. They also help regulate oil consumption.

Q: What does a flashing Check Engine Light indicate?
A: A flashing Check Engine Light usually signals a severe engine problem that requires immediate attention, such as a misfire.
Q: Explain the purpose of a compression test.
A: A compression test measures the pressure inside each cylinder during the compression stroke. Low compression readings can indicate worn piston rings, valve problems, or head gasket issues.
3. Repair Procedures
Q: How do you replace a timing belt?
A: Replacing a timing belt involves setting the engine to Top Dead Center (TDC), removing the old belt, installing the new belt according to the manufacturer’s specifications, and then verifying the timing marks.
Q: Describe the steps involved in replacing a fuel pump.
A: Replacing a fuel pump typically involves relieving fuel system pressure, disconnecting the fuel lines, removing the old pump, installing the new pump with a new filter, and then connecting the lines and priming the system.
