P2652 2008 Honda Accord Code - Rocker Arm Oil Pressure Switch 'B' Circuit High Voltage

Quick Answer

The VTEC system activates rocker arm oil control solenoid B by command from the Powertrain Control Module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that switches valve timing between Low and High. Common causes include Low engine oil level, Faulty Rocker Arm Oil Control Solenoid, Faulty EOP (Engine Oil Pressure) sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2652 2008 Honda Accord Description

The VTEC system activates rocker arm oil control solenoid B by command from the Powertrain Control Module (PCM), and it charges/discharges the hydraulic circuit of the VTEC mechanism that switches valve timing between Low and High. The PCM monitors oil pressure in the hydraulic circuit of the VTEC mechanism using rocker arm oil pressure switch B downstream of rocker arm oil control solenoid B. If there is a difference between the oil pressure condition in the hydraulic circuit determined by the PCM command and the oil pressure condition determined by the status of rocker arm oil pressure switch B, the system is considered faulty, and a DTC is stored.
