m m
Fuel injection system fault (Chapter 4).
Oil pressure warning light illuminated with engine
running
m m
Low oil level, or incorrect oil grade (Chapter 1).
m m

Note: Low oil pressure in a high-mileage engine at tickover is not
necessarily a cause for concern. Sudden pressure loss at speed is far
more significant. In any event, check the gauge or warning light sender
before condemning the engine.
