Resistance Check

  1. Remove engine cover. Disconnect connector from Oil Control Valve (OCV) to be tested. Oil control valves are located at front top of each cylinder head. On ES300, left OCV has a 2-pin connector with Green/Yellow and Green/Red wires. Right OCV has a 2-pin connector with Green/White and Green wires. On RX300, left OCV has a 2-pin connector with Green/Yellow and Green/Red wires. Right OCV has a 2-pin connector with Green/White and Yellow/Black wires.
  2. On all models, measure resistance between OCV terminals. Resistance should be 6.9-7.9 ohms at 68°F (20°C). If resistance is not 6.9-7.9 ohms, replace OCV.
