What causes a car to have high CO levels?
What causes a car to have high CO levels?
The engine control computer will determine how much fuel to inject into the combustion chambers based on this data. The more oxygen in the stream, the more fuel the computer will deliver, and visa-versa. A defective O2 sensor will cause increased carbon monoxide emissions.
What causes low engine temperature and high co?
Defective Engine Coolant Temperature (ECT) Sensor – Low engine temperature requires more fuel. When the ECU is unable to determine what the engine’s accurate temperature is, it will not adjust fuel delivery properly; resulting in high CO.
What causes high Co and rich fuel mixtures?
Below are common faults which are likely to produce high Carbon Monoxides (CO) and Rich Fuel Mixtures. Carbon Monoxide is a by-product of incomplete combustion. Carbon Monoxide exceeding maximum limits, can be due to a number of emission failures ranging from inadequate air intake to defective engine computer sensors.
What causes high hydrocarbon levels in an engine?
There are still many possible causes of high hydrocarbons, most of which are either internal engine problems or tough-to-detect induction system problems such as valve deposits or a leaking EGR valve. On fuel-injected vehicles, poor fuel atomization is a common cause of HC problems.

What causes a gasoline engine to produce so much co?
A gasoline engine producing 10,000 ppm CO at the ideal air-fuel ratio will produce over 60,000 ppm when the fuel is increased. Other causes of high CO production include; a cold engine, misfiring, incorrect engine timing, defective or worn parts, exhaust system leaks, and defective catalytic converters.
