The rocker arm oil pressure sensor detects engine oil pressure in the VTEC system. The rocker arm oil pressure sensor outputs low signal voltage at low pressure and high signal voltage at high pressure. If the rocker arm oil pressure sensor output voltage is excessively high or low, the powertrain control module (PCM) detects a malfunction and stores a DTC.
