Causes

Faulty electronic throttle body (ETB) or throttle actuator motor
Failed throttle position sensor (TPS) or accelerator pedal position sensor (APPS)
Damaged wiring, intermittent connection, corroded or bent connector pins between PCM, pedal module and throttle body
Low battery/charging system voltage or poor ground
PCM software anomaly or PCM internal fault
Previous mechanical obstruction or binding in throttle plate

Symptoms

Cruise control unavailable or disabled
Malfunction Indicator Lamp (MIL/CEL) may be illuminated
Possible reduced engine power / limp mode
Reduced or erratic throttle response, surging or poor idle
Driveability complaints that may be intermittent

What to check

Read freeze frame and all stored/ pending/active codes with a capable scan tool; note related ETCS and pedal codes
Verify battery voltage (engine off and cranking) and charging system health
Visually inspect throttle body, pedal module and PCM connectors for corrosion, bent pins, water intrusion or damaged terminals
Check harness for chafing, pinched sections, previous repairs or aftermarket splices
Monitor live data: throttle position, accelerator pedal positions A & B, throttle body command vs actual, motor current (if available)
Attempt to command the throttle plate with a scan tool (as allowed by manufacturer) and observe response

Signal parameters

Accelerator pedal position sensor A: ~0.2–4.8 V across travel (sensor B typically inverse)
Throttle position sensor (closed throttle): approx 0.2–1.0 V; wide open throttle: ~4.0–4.8 V (varies by model)
Throttle actuator supply: battery voltage (approx 12–14.5 V) on Vb feed; dedicated low-side/ground return must be good
Control signal to throttle motor: PWM duty cycle or voltage modulated by PCM (varies with commanded position)
System voltage while cranking should not drop below ~9.5–10 V during tests; known acceptable operating voltage >11 V
CAN bus/communication lines: normal activity and no bus errors when scanning

Diagnostic algorithm

Connect a quality scan tool and record all codes, freeze frame, and live data for throttle position and pedal sensors. Note if code is current, pending, or history.
Verify battery voltage and charging system. Recharge or replace battery if low; ensure clean ground at engine and chassis.
Perform visual inspection of throttle body, pedal module and PCM connectors. Repair any corrosion, bent pins or poor terminal engagement.
With key on engine off, measure APPS A and B voltages at connector — confirm both produce correct and correlated signals across pedal travel and that values are within manufacturer ranges.
Measure TPS output at throttle body across closed to wide open positions and compare to commanded position in live data. Look for non-correlating or stuck readings.
Check continuity and resistance of wiring between throttle body and PCM/pedal module (with power disconnected). Repair any open/shorts.
Command throttle plate via scan tool (if supported) and observe response and motor current. If throttle does not move or motor draws excessive current, suspect ETB motor or mechanical binding.
If wiring and sensors are good but code persists, check for PCM updates/TSBs and perform recommended relearn/calibration procedure for the throttle body per Ford procedure.
If all else passes and intermittent faults continue, consider replacing throttle body or pedal module as indicated by data, or consult dealer for PCM-level diagnostics.
After repair, clear codes, perform throttle relearn, and road test to confirm cruise functionality restored and no recurrence.

Likely causes

Contaminated/corroded connector or broken wire to the throttle body
Faulty throttle body (motor or internal sensor) causing monitor failure
Faulty pedal position sensor or incorrect pedal signal correlation
Low system voltage or poor ground affecting control/monitoring circuits
PCM requiring software update or replacement (less common)
