Volvo 240 Lambda control ECU Up for sale is a Working, in excellent condition Volvo 240 Engine Lambda control ECU. Part number-- 0 280 800 053. This unit is the original for any 82 240 non-turbo 4cyl model, probably others near this range but it is the buyers responsibility to find this out.As always your best bet is to match the part numbers with the part you need. Even though these cars have CIS, the lambda control unit can adjust fuel pressure with it's sensor inputs. A faulty Lambda ECU can cause a whole hots of issues with these cars, including non running, and random cutting out (but usually it will re-start moments later). Also idle control & emission issues are possible (excess smoke or overheating caused by lean running). Hot or cold start issues can be caused as well. These units are no longer available almost everywhere and VERY hard to find used. If you can find a new one, they are usually in the $1000+ range. Ouch, not here! This comes with a 30 day warranty.
