P0562: System Voltage Low
What Does P0562 Mean?
P0562 is a diagnostic trouble code indicating: System Voltage Low. This code relates to the vehicle speed and idle control system. It has been reported in NHTSA complaints across 7 different vehicle models.
The vehicle speed and idle control systems manage engine operation at rest and in motion. The Vehicle Speed Sensor (VSS) provides real-time speed data used for fuel calculations, shift timing, cruise control, ABS, and speedometer display. The Idle Air Control (IAC) system regulates airflow to maintain target idle speed (typically 600-900 RPM). On electronic throttle control vehicles, the ECM uses the throttle body motor directly. When the ECM detects faults in these systems, drivability problems like stalling, surging, incorrect speedometer readings, and cruise control failure are common. Speed sensor failures are often caused by metal debris from internal transmission wear accumulating on the magnetic sensor tip. Idle problems are most commonly caused by carbon buildup in the throttle body restricting airflow.
Symptoms of P0562
- ⚠️ Check engine light on
- ⚠️ Erratic or inoperative speedometer
- ⚠️ Unstable idle — surging, hunting, or stalling
- ⚠️ Cruise control not working
- ⚠️ Transmission shift quality issues
- ⚠️ ABS or traction control warning light
Common Causes
- 🔍 Faulty vehicle speed sensor or idle control valve
- 🔍 Carbon buildup in throttle body
- 🔍 Vacuum leak affecting idle control
- 🔍 Wiring issue in sensor or actuator circuit
- 🔍 ECM or instrument cluster fault

Diagnostic Tips
- For speed sensor codes: check if speedometer works — if not, output speed sensor is likely bad
- For idle codes: clean throttle body first — carbon buildup is #1 cause
- Check for vacuum leaks with smoke machine
- On electronic throttle vehicles, throttle body relearn may be required after cleaning
Common Mistakes to Avoid
- ❌ Replacing idle air control valve without cleaning throttle body
- ❌ Not performing throttle body relearn after cleaning
- ❌ Ignoring vacuum leaks as cause of idle problems
