1978 Volvo 242 244 245 pg. 51 Emission control system Oxygen sensor system This is a self-tuning engine control system designed to reduce emissions and improve fuel economy. An oxygen sensor monitors the composition of the exhaust gases leaving the engine. The exhaust gas analysis is fed into an electronic unit which continuously influences a frequency valve. This adjusts the air-fuel ratio to provide optimum conditions for combustion and efficient reduction of the three major pollutants (hydrocarbons, carbon monoxide and nitrous gases) through a 3-way catalytic converter. Change oxygen sensor unit and Inspect electrical connections of oxygen sensor system The oxygen sensor must be replaced every 15,000 miles. At the same time the electrical wires and connections of the oxygen sensor system should be inspected for chafing and corrosion. Replace as necessary. Special instructions for work on the fuel injection system Extreme cleanliness is essential when working on the injection system. Great care must be observed. Injection system service should be handled by qualified technicians, using equipment intended for this service. Fuel (line) filter The fuel filter is located on the firewall. This filter is to be changed every 30,000 miles. The filter is replaced as one complete unit. Replace more frequently if contaminated fuel was introduced into the tank. Air cleaner Replace the air cleaner cartridge with a new one every 30,000 miles. The cartridge should be replaced more often when driving under dirty and dusty conditions. No cleaning of any kind is to be accomplished. file:///K|/ownersdocs/1978/1978_242_244_245/78242244245_03a.htm (11 of 15)12/22/2006 10:11:27 PM
