Camshaft Position Sensor
2012 Ford F-150 · 5.0L V8 Coyote
Sensor Type
hall-effect
Waveform Type
dc-square
Location
Bank 1 (passenger side) and Bank 2 (driver side) sensors mounted in the front timing cover, reading camshaft position wheels; typically referring to Bank 1 intake cam sensor
Pins
3-pin connector
Idle Frequency
11.67 Hz
Timebase
50ms/div
Voltage Scale
2V/div
Trigger
2.5V, rising edge
Wiring
Brown/White (12V power), Black/White (ground), and Gray/Orange (signal)
Expected Voltage Range
At Idle
0.2V to 5V
At Higher RPM
0.2V to 5V
Expected Pattern
Multiple square wave pulses per camshaft revolution, switching cleanly between 0.2V (low) and 5.0V (high) with variable pulse widths for cylinder identification
Known-Good Waveform
Expect clean digital square wave transitions with sharp rising and falling edges between 0.2V and 5.0V. The Coyote uses a unique pattern per camshaft revolution for cylinder identification, with varying pulse widths. At idle (700 RPM), the camshaft rotates at half crankshaft speed, producing approximately 12 Hz base frequency with the characteristic Ford variable-width pulse pattern.
Common Failure Patterns
Slow rise/fall times, rounded edges, or voltage levels not reaching proper high (above 4.5V) or low (below 0.5V) states
Cause: Weak sensor output due to internal Hall-effect IC failure or low supply voltage from wiring resistance
Intermittent signal dropout or missing pulses
Cause: Timing chain stretch affecting sensor-to-wheel air gap, worn cam phaser, or loose sensor mounting
Diagnostic Tips
The Coyote's Twin Independent Variable Camshaft Timing (Ti-VCT) system means cam timing correlation codes (P0016/P0017) are common; verify actual mechanical timing before replacing sensors. Always check all four cam sensors when diagnosing correlation faults.
