Symptoms of P0082
- Check-engine light on, sometimes with rough or uneven running.
- Hesitation, surging, or a noticeable change in fuel economy.
- Occasionally hard starting or a smell of unburnt fuel.
Common causes of P0082
- A failing or contaminated sensor (MAF, MAP, oxygen or air-fuel sensor).
- Intake or vacuum leaks, or an exhaust leak near an upstream sensor.
- Wiring, connector, or fuel-delivery problems that skew the reading.
Useful checks before replacing parts
- Measure bank 2 intake solenoid control voltage, feed, ground, resistance, and current while checking for short-to-ground faults.
- Inspect connector condition, oil contamination, harness routing near the cylinder head, fuse supply, and module driver command.
- Compare low circuit behavior with commanded intake cam timing, actual cam angle, and freeze-frame voltage or oil temperature.
