Technician A says that a CKP sensor sends a pulsed signal to the PCM to determine engine speed. Technician B says that the CKP speed signal is compared to the transmission input shaft speed sensor to determine torque converter slippage. Who is correct?
A) Technician A
B) Technician B
C) Both Technicians A and B
D) Neither Technician A nor B

Question

Quizplus · Accepted Answer

Technician A is correct because the CKP (Crankshaft Position) sensor does send a pulsed signal to the PCM (Powertrain Control Module) to determine engine speed. Technician B is also correct because the PCM can compare the CKP speed signal to the transmission input shaft speed sensor to determine torque converter slippage.
