Typical CPS lifespan is about 150-200,000 miles. Crank Position Sensors can have intermittent "thermal failure". This means that the CPS/CKP fails when the engine gets hot, but works again when it cools back down. Typical CPS Symptoms, (not all symptoms may be present, or occur at the same time) -. - Random stalling.
A crankshaft angle sensor is designed to detect the rotation of the crankshaft while the engine is running and is responsible for triggering the fuel injection and ignition system via the main PCM computer.This crank sensor will be located at the lower section of the block and can either be at the front, rear or middle of the engine at the crankshaft level.
Here are some specifics of the crankshaft position sensor: The 4.6L, 5.4L CKP sensor is a two wire variable reluctance sensor. What this means is that: It doesn't need an external power source or a Ground source (like in a 3 wire type Hall Effect sensor). The CKP sensor creates its own signal (AC Volt signal).
