ENGINE OIL PRESSURE
(Engine oil pressure too low)
An EOP sensor signal voltage applied to
ECM remains lower than the specified value
continuously for 10 seconds or more when
the engine speed is 1,000 rpm or more.
• Decrease in engine oil pressure
• Decrease in engine oil level
• Engine oil condition
• EOP sensor
• Engine body
Selector lever
• P or N position (CVT)
• N position (M/T)
