That indicator is for the lambda sensor, that reverse check mark thing is the greek letter lambda. lambda sensor is another name for the oxygen sensor. it is part of how the engine computer manages emissions and it also contributes to fuel economy. if it becomes defective and is not replaced the system may eventually foul your catalytic converter. hope that helps

That is a "Lambda" symbol.
Volvos "Check engine" lamp.

If this one lits, there is possible that there is some trouble with the oxugene sensor or enginge electronics.

If only lit before the engine starts: All OK.

1994 Volvo 940 Station Wagon timing belt


I hope you've solved the problem by now, but there are alignment marks on the crank shaft (top pulley), idler (lower side), and cam shaft (smaller, bottom pulley) which should be aligned with stationary marks on the timing belt rear cover.

The belt has marks that align with the aforementioned marks (lines). The double marks on the belt align with the camshaft marks and the single marks with the others.

Loosen the tensioner clamp (nut) to allow the spring loaded tensioner to press on the belt and retighten the nut.

Rotate the crank shaft (clockwise, probably two revolutions) and make sure the pulley marks realign to the marks on the cover (they don't have to realign with the marks on the belt).

Rotate the crank shaft a full revolution once the belt is on and check that alignment is preserved.

Periodically loosen and retension the tensioner nut (access through a hole in the cover) to ensure that tension is maintained as the belt relaxes.
