Chapter 26, Problem 8ASRQ
While discussing El systems: Technician A says that when the engine is being cranked, the PCM relies only on the signals from the ECT to determine initial ignition timing. Technician B says that when an engine is initially started and is running at a predetermined speed, the PCM looks at several inputs, including engine speed, load, throttle position, and engine coolant temperature, and makes adjustments accordingly. Who is correct?
a. Technician A
b. Technician B
c. Both A and B
d. Neither A nor B
