Causes
- Corroded or loose connector or wiring to the electronic throttle body (ETB).
- Failing throttle actuator motor or internal ETB electronics.
- Contaminated or sticking throttle plate (carbon build-up).
- Faulty throttle position sensor(s) or bad sensor signals.
- Low battery voltage or poor charging system causing inadequate supply to actuator.
- Intermittent short or open in control wiring (power, ground, signal).
Symptoms
- Check Engine Light (MIL) illuminated and P2119 stored.
- Reduced engine power or limp-home mode with limited throttle response.
- Delayed or erratic throttle response, hesitation or surging.
- High, low, or unstable idle RPM.
- Vehicle may stall or hesitate at low speed.
What to check
- Read freeze frame and all stored codes; note any related throttle/pedal codes.
- Verify battery voltage (should be ~12.4–14.5 V) during key on and while cranking/operating.
- Inspect throttle body connector and wiring harness for damage, corrosion, or loose pins.
- Scan tool: monitor commanded throttle position (CTP) vs actual throttle position (ATP)/throttle plate angle in real time.
- Backprobe throttle body connector to verify motor supply power, ground, and sensor signal voltages.
- Check for mechanical binding by slowly actuating throttle blade (with ignition off, where design permits) and inspect for carbon build-up or obstruction.
Signal parameters
- Commanded Throttle Position (CTP) vs Actual Throttle Position (ATP) — difference >10–20% may trigger code (varies by manufacturer).
- Throttle position sensor voltages typically ~0.5–4.5 V across range (two sensors usually inverse correlated).
- Actuator motor supply voltage ~9–14 V when commanded; no supply indicates open/fuse/relay issue.
- Idle/closed throttle position: ATP near 0–10% (or low voltage ~0.5–1.0 V depending on sensor).
- Wide open throttle: ATP near 85–100% (or ~4.0–4.5 V depending on sensor).
- Motor current pulses/drive signals present when throttle commanded to move (use oscilloscope for detailed waveform analysis).
Diagnostic algorithm
- Retrieve codes and freeze frame; note operating conditions when fault set. Clear codes and attempt to reproduce.
- Verify battery and charging system condition. Recharge/replace battery if voltage low before further tests.
- Visually inspect ETB connector and wiring for corrosion, bent pins, damaged insulation, or water intrusion. Repair as needed.
- With scan tool connected, command throttle positions and observe CTP vs ATP. Note any large discrepancies or lack of movement.
- Backprobe connector: verify reference voltage, sensor signal voltages, and ground continuity. Check motor supply voltage when throttle is commanded to move.
- Perform wiggle and load tests on wiring while monitoring live data to find intermittent opens/shorts.
- Inspect and clean throttle plate and bore if carbon build-up or sticking is present. Re-test after cleaning.
- Check throttle actuator motor resistance and continuity per vehicle-specific spec. Replace throttle body if motor or internal electronics out of spec.
- Perform throttle body relearn/calibration procedure if repairs or cleaning performed (follow OEM procedure).
- If wiring, connector, and throttle body check good and issue persists, consider PCM firmware update or replacement and consult manufacturer service information.
- After repair, clear codes and road-test to confirm fault does not return.
Likely causes
- Poor electrical connection at throttle body (corrosion, bent pins).
- Dirty or mechanically binding throttle plate restricting movement.
- Damaged throttle actuator motor or internal circuit failure in throttle body assembly.
- Bad throttle position sensor feedback (out of range or noisy signal).
- Battery or charging system low during test causing marginal actuator operation.
Fault status
Status
PCM detected throttle actuator A (throttle body) range or performance out of specification — commanded throttle position does not match actual throttle position or actuator response is abnormal.
Repair difficulty: Medium
Diagnostic time: 1.0 - 3.0 hours
