1. An engine will not start. The technician uses a scan tool and finds DTC (Diagnostic Trouble Code) P0335 (Crankshaft Position Sensor [CKP]) stored. This vehicle has electronic ignition without a distributor. Which of the following is the MOST likely cause?
2. Two technicians are discussing the ECM (engine control module) reprogramming process. Technician A says the first step in the reprogramming procedure is to determine the current software needed.

3. Which of the following would indicate a closed EGR (Exhaust Gas Recirculation) valve?
4. A vehicle with a no-start concern has been checked with a spark checker and has no spark to the plugs. Technician A says to test for battery voltage at the ignition coil by connecting the red lead of a DMM (Digital Multimeter) to the coil negative terminal and black lead to a good ground. Technician B says with the DMM red lead on the coil negative terminal and the black lead grounded, the voltage should fluctuate while cranking the engine. Who is right?
5. Which I/M (Inspection/Maintenance) test uses a dynamometer that places a "single weight" load on the vehicle?
