NOTE:

• Due to the structure of the engine oil level sensor, a value exceeding the measurable upper limit value may be detected. If the oil level gauge is the upper limit position or more and the engine oil level sensor output value exceeds the measurable upper limit value, adjust the engine oil level near the middle of the lower and upper limit positions on the dipstick, and then verify the output value of the engine oil level sensor (PID: OIL_LEVEL) again.
• If it cannot be verified, replace the engine oil level sensor. (See ENGINE OIL LEVEL SENSOR REMOVAL/INSTALLATION .)
