P25E2"A" Camshaft Position Control Performance (Bank 2)
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P25E2 points to poor position control of the bank 2 intake camshaft actuator: the measured angle tracks its target less accurately or with more oscillation than the calibration allows, while no clear lock fault is present. It is the bank 2 sibling of P25DF. No manufacturer publishes its trigger, so it remains unclear how it is separated from P0021 (bank 2 over-advanced or system performance) or the slow response code P000C; when one of those is stored too, it usually guides the diagnosis. CARB 13 CCR 1968.2 wants every VVT system checked for missed setpoints and for being too slow. In hydraulic phasers of the mid-lock type, as BorgWarner supplies for the Hyundai Gamma II, contaminated oil, a weak solenoid valve or internal leakage reduce control precision. Symptoms tend to be mild: unsteady idle and lower efficiency.
- What you may notice
- Check engine lamp on

- RareInternal leakage across the phaser vanes
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
